Hospital-related infections have been widely reported during the ongoing coronavirus outbreak, with healthcare professionals bearing a disproportionate risk. However, a proactive response in Hong Kong’s public hospital system appears to have bucked this trend and successfully protected both patients and staff from SARS-CoV-2, according to a study published online today in Infection Control & Hospital Epidemiology.

During the first 42 days of the outbreak, the 43 hospitals in the network tested 1275 suspected cases and treated 42 patients with confirmed COVID-19, the disease caused by SARS-CoV-2 infection. Yet, there were no nosocomial infections or infections among healthcare personnel, report Vincent C.C. Cheng, MD, FRCPath, the hospital’s infection control officer, and colleagues.

Cheng and colleagues note that 11 out of 413 healthcare workers who treat patients with confirmed infections had unprotected exposure and were in quarantine for 14 days, but none became ill.

In comparison, they note, the 2003 SARS outbreak saw almost 60% of nosocomial cases occurring in healthcare workers.

Proactive bundle

The Hong Kong success story may be due to a stepped-up proactive bundle of measures that included enhanced laboratory surveillance, early airborne infection isolation, and rapid-turnaround molecular diagnostics. Other strategies included staff forums and one-on-one discussions about infection control, employee training in protective equipment use, hand-hygiene compliance enforcement, and contact tracing for workers with unprotected exposure.

In addition, surgical masks were provided for all healthcare workers, patients, and visitors to clinical areas, a practice previously associated with reduced in-hospital transmission during influenza outbreaks, the authors note.

Hospitals also mandated use of personal protective equipment (PPE) for aerosol-generating procedures (AGPs), such as endotracheal intubation, open suctioning, and high-flow oxygen use, as AGPs had been linked to nosocomial transmission to healthcare workers during the 2003 SARS outbreak.

The infection control measures, which were part of a preparedness plan developed after the SARS outbreak, were initiated on December 31, when the first reports of a cluster of infections came from Wuhan, China.

As the outbreak evolved, the Hong Kong hospitals quickly widened the epidemiologic criteria for screening, from initially including only those who had been to a wet market in Wuhan within 14 days of symptom onset, to eventually including anyone who had been to Hubei province, been in a medical facility in mainland China, or in contact with a known case.  

All suspected cases were sent to an airborne-infection isolation room (AIIR) or a ward with at least a meter of space between patients.

“Appropriate hospital infection control measures could prevent nosocomial transmission of SARS-CoV-2,” the authors write. “Vigilance in hand hygiene practice, wearing of surgical mask in the hospital, and appropriate use of PPE in patient care, especially [when] performing AGPs, are the key infection control measures to prevent nosocomial transmission of SARS-CoV-2 even before the availability of effective antiviral agents and vaccine.”

Asked for his perspective on the report, Aaron E. Glatt, MD, chairman of the department of medicine and chief of infectious diseases at Mount Sinai South Nassau in Oceanside, New York, said that apart from the widespread issuing of surgical masks to workers, patients, and visitors, the measures taken in Hong Kong are not different from standard infection-control practices in American hospitals. Glatt, who is also a hospital epidemiologist, said it was unclear how much impact the masks would have.

“Although the infection control was impressive, I don’t see any evidence of a difference in care,” he told Medscape Medical News.

Could zero infection transmission be achieved in the more far-flung and variable settings of hospitals across the United States? “The ability to get zero transmission is only possible if people adhere to the strictest infection-control guidelines,” Glatt said. “That is clearly the goal, and it will take time to see if our existing strict guidelines are sufficient to maintain zero or close to zero contamination and transmission rates in our hospitals.”

Rather than looking to change US practices, he stressed adherence to widely established tenets of care. “It’s critically important to keep paying close attention to the basics, to the simple blocking and tackling, and to identify which patients are at risk, and therefore, when workers need protective equipment,” he said.

“Follow the recommended standards,” continued Glatt, who is also a spokesperson for the Infectious Diseases Society of America and did not participate in this study.

In a finding from an ancillary pilot experiment, the Hong Kong researchers found exhaled air from a patient with a moderate coronavirus load showed no evidence of the virus, whether the patient was breathing normally or heavily, speaking, or coughing. And spot tests around the room detected the virus in just one location.

“We may not be able to make a definite conclusion based on the analysis of a single patient,” the authors write. “However, it may help to reassure our staff that the exhaled air may be rapidly diluted inside the AIIR with 12 air changes per hour, or probably the SARS-CoV-2 may not be predominantly transmitted by [the] airborne route.”

However, a recent Singapore study showed widespread environmental contamination by SARS-CoV-2 through respiratory droplets and fecal shedding, underlining the need for strict adherence to environmental and hand hygiene. Post-cleaning samples tested negative, suggesting that standard decontamination practices are effective. 

This work was partly supported by the Consultancy Service for Enhancing Laboratory Surveillance of Emerging Infectious Diseases of the Department of Health, Hong Kong Special Administrative Region; and the Collaborative Innovation Center for Diagnosis and Treatment of Infectious Diseases, Ministry of Education of China. The authors and Glatt have disclosed no relevant financial relationships.

The Centers for Medicare & Medicaid Services issued two guidance documents related to helping contain the spread of the coronavirus, primarily aimed at ensuring that health care providers are implementing proper infection control procedures.

The first guidance document, “Guidance for Infection Control and Prevention Concerning Coronavirus Disease (COVID-19): FAQs and Considerations for Patient Triage, Placement and Hospital Discharge,” issued March 4, provides some basic guidance, including identifying which patients are at risk, how facilities should screen for COVID-19, how facilities should monitor or restrict health care facility staff, and other recommendations for infection prevention and control.

“Hospitals should identify visitors and patients at risk for having COVID-19 infection before or immediately upon arrival to the healthcare facility,” the guidance document notes. “For patients, implement respiratory hygiene and cough etiquette (i.e., placing a face mask over the patient’s nose and mouth if that has not already been done) and isolate the patient in an examination room with the door closed. If the patient cannot be immediately moved to an examination room, ensure they are not allowed to wait among other patients seeking care.”

The document offers further information regarding the care of patients and provides numerous links to existing guidance from the Centers for Disease Control and Prevention.

The second document, “Guidance for Infection Control and Prevention of Coronavirus Disease 2019 (COVID-19) in Nursing Homes,” issued the same day, provides information on how to limit and monitor visitors as well as monitor and restrict health staff. It details when to transfer residents with suspected or confirmed coronavirus infection, and when a nursing home should accept a resident diagnosed with COVID-19.

Facilities “should contact their local health department if they have questions or suspect a resident of a nursing home has COVID-19,” the document states. “Per CDC, prompt detection, triage and isolation of potentially infectious patients are essential to prevent unnecessary exposure among patients, healthcare personnel, and visitors at the facility.”

The CMS also announced that it is suspending all nonemergency survey activity.

“CMS is suspending nonemergency inspections across the country, allowing inspectors to turn their focus on the most serious health and safety threats like infectious diseases and abuse,” the agency stated in a March 4 memo. “This shift in approach will also allow inspectors to focus on addressing the spread of ... COVID-19. CMS is issuing this memorandum to State Survey Agencies to provide important guidelines for the inspection process in situations in which a COVID-19 is suspected.”

In a statement, CMS Administrator Seema Verma said these actions “represent a call to action across the health care system. All health care providers must immediately review their procedures to ensure compliance with CMS’ infection control requirements, as well as the guidelines from the Centers for Disease Control and Prevention.”

The Food and Drug Administration has issued a Drug Safety Communication that strengthens existing warnings about serious mood- and behavior-related changes associated with montelukast (Singulair), a prescription drug for asthma and allergy.

The new boxed warning advises health care providers to avoid prescribing montelukast for patients with mild symptoms, particularly those with allergic rhinitis, the FDA said in a press release. The drug was first approved in 1998, and the product labeling was updated in 2008 to include information about neuropsychiatric adverse events reported with usage of montelukast.

While the Sentinel study, along with other observational studies, did not find an increased risk of mental health side effects with montelukast treatment, compared with inhaled corticosteroids, those studies had limitations that may have affected results, the FDA said in the Drug Safety Communication. However, the FDA has continued to receive reports of neuropsychiatric events – including agitation, depression, sleeping problems, and suicidal thoughts and actions – in patients receiving the medication.

“The incidence of neuropsychiatric events associated with montelukast is unknown, but some reports are serious, and many patients and health care professionals are not fully aware of these risks,” Sally Seymour, MD, director of the division of pulmonary, allergy and rheumatology products in the FDA’s Center for Drug Evaluation and Research, said in the press release. “There are many other safe and effective medications to treat allergies with extensive history of use and safety, such that many products are available over the counter without a prescription.”

In addition to the boxed warning, the FDA now requires a new medication guide to be given to patients with each montelukast prescription, the FDA said.

The White House Coronavirus Task Force appeared at a press briefing March 2 to provide updates about testing strategies and public health coordination to address the current outbreak of the coronavirus COVID-19. Speaking at the briefing, led by Vice President Mike Pence, Centers for Disease Control and Prevention (CDC) director Robert Redfield, MD, said, “Working with our public health partners we continue to be able to identify new community cases and use our public health efforts to aggressively confirm, isolate, and do contact tracking.” Calling state, local, tribal, and territorial public health departments “the backbone of the public health system in our country,” Dr. Redfield noted that he expected many more confirmed COVID-19 cases to emerge.

At least some of the expected increase in confirmed cases of COVID-19 will occur because of expanded testing capacity, noted several of the task force members. On Feb. 29, the Food and Drug Administration issued a new policy to expedite the process for some laboratories to develop new diagnostic tests for SARS-CoV2, the virus that is causing the current outbreak of COVID-19.

Highly qualified laboratories, including both those run by public agencies and private labs, are now authorized to begin using their own validated test for the virus as long as they submit an Emergency Use Authorization (EUA) to the Food and Drug Administration within 15 days of notifying the agency of validation.

“To effectively respond to the COVID-19 outbreak, rapid detection of cases and contacts, appropriate clinical management and infection control, and implementation of community mitigation efforts are critical. This can best be achieved with wide availability of testing capabilities in health care settings, reference and commercial laboratories, and at the point of care,” the agency wrote in a press announcement of the expedited test expansion.

On Feb. 4, the Secretary of the Department of Health & Human Services declared a coronavirus public health emergency. The FDA was then authorized to allow individual laboratories with validated coronavirus tests to begin testing samples immediately. The goal is a more rapid and expanded testing capacity in the United States.

“The global emergence of COVID-19 is concerning, and we appreciate the efforts of the FDA to help bring more testing capability to the U.S.,” Nancy Messonnier, MD, director of the CDC’s National Center for Immunization and Respiratory Diseases (NCIRD), said in the press release.

The new guidance that permits the immediate use of clinical tests after individual development and validation, said the FDA, only applies to labs already certified to perform high complexity testing under Clinical Laboratory Improvement Amendments. Many governmental, academic, and private laboratories fall into this category, however.

“Under this policy, we expect certain laboratories who develop validated tests for coronavirus would begin using them right away prior to FDA review,” said Jeffrey Shuren, MD, JD, director of the FDA’s Center for Devices and Radiological Health. “We believe this action will support laboratories across the country working on this urgent public health situation,” he added in the press release.

“By the end of this week, close to a million tests will be available,” FDA Commissioner Stephen M. Hahn, MD, said during the March 2 briefing.*

Updated criteria

The CDC is maintaining updated criteria for the virus testing on its website. Testing criteria are based both on clinical features and epidemiologic risk.

Individuals with less severe clinical features – those who have either fever or signs and symptoms of lower respiratory disease such as cough or shortness of breath, but who don’t require hospitalization – should be tested if they have high epidemiologic risk. “High risk” is defined by the CDC as any individual, including health care workers, who has had close contact with a person with confirmed COVID-19 within the past 2 weeks. For health care workers, testing can be considered even if they have relatively mild respiratory symptoms or have had contact with a person who is suspected, but not yet confirmed, to have coronavirus.

In its testing guidance, the CDC recognizes that defining close contact is difficult. General guidelines are that individuals are considered to have been in close contact with a person who has COVID-19 if they were within about six feet of the person for a prolonged period, or cared for or have spent a prolonged amount of time in the same room or house as a person with confirmed COVID-19.

Individuals who have both fever and signs or symptoms of lower respiratory illness who require hospitalization should be tested if they have a history of travel from any affected geographic area within 14 days of the onset of their symptoms. The CDC now defines “affected geographic area” as any country or region that has at least a CDC Level 2 Travel Health Notice for COVID-19, so that the testing criteria themselves don’t need to be updated when new geographic areas are included in these alerts. As of March 3, China, Iran, Italy, Japan, and South Korea all have Level 2 or 3 travel alerts.

The CDC now recommends that any patient who has severe acute lower respiratory illness that requires hospitalization and doesn’t have an alternative diagnosis should be tested, even without any identified source of exposure.

“Despite seeing these new cases, the risk to the American people is low,” said the CDC’s Dr. Redfield. In response to a question from the press about how fast the coronavirus will spread across the United States, Dr. Redfield said, “From the beginning we’ve anticipated seeing community cases pop up.” He added that as these cases arise, testing and public health strategies will focus on unearthing linkages and contacts to learn how the virus is spreading. “We’ll use the public health strategies that we can to limit that transmission,” he said.

Highly qualified laboratories, including both those run by public agencies and private labs, are now authorized to begin using their own validated test for the virus as long as they submit an Emergency Use Authorization (EUA) to the Food and Drug Administration within 15 days of notifying the agency of validation.

“To effectively respond to the COVID-19 outbreak, rapid detection of cases and contacts, appropriate clinical management and infection control, and implementation of community mitigation efforts are critical. This can best be achieved with wide availability of testing capabilities in health care settings, reference and commercial laboratories, and at the point of care,” the agency wrote in a press announcement of the expedited test expansion.

On Feb. 4, the Secretary of the Department of Health & Human Services declared a coronavirus public health emergency. The FDA was then authorized to allow individual laboratories with validated coronavirus tests to begin testing samples immediately. The goal is a more rapid and expanded testing capacity in the United States.

“The global emergence of COVID-19 is concerning, and we appreciate the efforts of the FDA to help bring more testing capability to the U.S.,” Nancy Messonnier, MD, director of the CDC’s National Center for Immunization and Respiratory Diseases (NCIRD), said in the press release.

The new guidance that permits the immediate use of clinical tests after individual development and validation, said the FDA, only applies to labs already certified to perform high complexity testing under Clinical Laboratory Improvement Amendments. Many governmental, academic, and private laboratories fall into this category, however.

“Under this policy, we expect certain laboratories who develop validated tests for coronavirus would begin using them right away prior to FDA review,” said Jeffrey Shuren, MD, JD, director of the FDA’s Center for Devices and Radiological Health. “We believe this action will support laboratories across the country working on this urgent public health situation,” he added in the press release.

“By the end of this week, close to a million tests will be available,” FDA Commissioner Stephen M. Hahn, MD, said during the March 2 briefing.*

Updated criteria

The CDC is maintaining updated criteria for the virus testing on its website. Testing criteria are based both on clinical features and epidemiologic risk.

Individuals with less severe clinical features – those who have either fever or signs and symptoms of lower respiratory disease such as cough or shortness of breath, but who don’t require hospitalization – should be tested if they have high epidemiologic risk. “High risk” is defined by the CDC as any individual, including health care workers, who has had close contact with a person with confirmed COVID-19 within the past 2 weeks. For health care workers, testing can be considered even if they have relatively mild respiratory symptoms or have had contact with a person who is suspected, but not yet confirmed, to have coronavirus.

In its testing guidance, the CDC recognizes that defining close contact is difficult. General guidelines are that individuals are considered to have been in close contact with a person who has COVID-19 if they were within about six feet of the person for a prolonged period, or cared for or have spent a prolonged amount of time in the same room or house as a person with confirmed COVID-19.

Individuals who have both fever and signs or symptoms of lower respiratory illness who require hospitalization should be tested if they have a history of travel from any affected geographic area within 14 days of the onset of their symptoms. The CDC now defines “affected geographic area” as any country or region that has at least a CDC Level 2 Travel Health Notice for COVID-19, so that the testing criteria themselves don’t need to be updated when new geographic areas are included in these alerts. As of March 3, China, Iran, Italy, Japan, and South Korea all have Level 2 or 3 travel alerts.

The CDC now recommends that any patient who has severe acute lower respiratory illness that requires hospitalization and doesn’t have an alternative diagnosis should be tested, even without any identified source of exposure.

“Despite seeing these new cases, the risk to the American people is low,” said the CDC’s Dr. Redfield. In response to a question from the press about how fast the coronavirus will spread across the United States, Dr. Redfield said, “From the beginning we’ve anticipated seeing community cases pop up.” He added that as these cases arise, testing and public health strategies will focus on unearthing linkages and contacts to learn how the virus is spreading. “We’ll use the public health strategies that we can to limit that transmission,” he said.

The White House Coronavirus Task Force appeared at a press briefing March 2 to provide updates about testing strategies and public health coordination to address the current outbreak of the coronavirus COVID-19. Speaking at the briefing, led by Vice President Mike Pence, Centers for Disease Control and Prevention (CDC) director Robert Redfield, MD, said, “Working with our public health partners we continue to be able to identify new community cases and use our public health efforts to aggressively confirm, isolate, and do contact tracking.” Calling state, local, tribal, and territorial public health departments “the backbone of the public health system in our country,” Dr. Redfield noted that he expected many more confirmed COVID-19 cases to emerge.

In a typical year, March marks the start of conference season, made all the more attractive by collegial gatherings and travel to warmer climes. But 2020 has already proven anything but typical as the number of novel coronavirus cases continues to increase around the globe. As a potential pandemic looms, these meetings – full of handshakes and crowded lecture halls – are also nirvana for opportunistic viruses. As are the airports, airplanes, and cabs required to get there.

So, as COVID-19 continues to spread, medical and scientific societies must make some difficult decisions. In Europe, at least a few societies have already suspended their upcoming meetings, while France has temporarily banned all gatherings over 5000 people.

In the United States, however, most medical conferences are moving forward as planned – at least for now. But one conference of 10,000 attendees, the American Physical Society annual meeting, which was scheduled for March 2-6 in Denver, was canceled the day before the meeting started. Although it’s not a medical conference, it speaks to the “rapidly escalating health concerns” that all conference organizers must grapple with.

Due to rapidly escalating health concerns relating to the spread of the coronavirus disease (COVID-19), the 2020 APS March Meeting in Denver, CO, has been canceled. Please do not travel to Denver to attend the March Meeting. More information will follow shortly. #apsmarch

Just one smaller medical meeting, the Ataxia Conference, which was scheduled for March 6-7 in Denver, has been canceled.

Most societies hosting these meetings have put out statements to their attendees saying that they’re monitoring the situation and will adapt as necessary. The United States and Canadian Academy of Pathology, which is holding its annual meeting in Los Angeles this week, sent out an email beforehand asking international travelers to consider staying home. The Healthcare Information and Management Systems Society (HIMSS) Global Health Conference, which is slated to have about 50,000 attendees from around the world, has declared itself a “handshake-free” conference but otherwise intends to move ahead as planned.

All of these conferences will be pushing forward without at least one prominent group of attendees. New York University’s Langone Health has removed its employees from the decision-making process and instead is taking a proactive stance: The health system just declared a 60-day (minimum) ban preventing employees from attending any meetings or conferences and from all domestic and international work-related travel.

Here’s what some of the societies have said to attendees about their intent to proceed or modify their plans:

• Conference on Retroviruses and Opportunistic Infections (CROI), Boston, 3/8/20 - 3/11/20: Monitoring the situation and seeking input from local, state, and federal infectious-disease and public-health experts. Final decision expected by the evening of March 3.
• American Academy of Allergy, Asthma & Immunology (AAAAI), Philadelphia, 3/13/20 - 3/16/20: Monitoring developments but no plans to cancel or postpone at this time.
• American Academy of Orthopedic Surgeons (AAOS), Orlando, 3/24/20 - 3/28/20: Proceeding as planned.
• American Academy of Dermatology (AAD), Denver, 3/20/20 - 3/24/20: The AAD’s 2020 Annual Meeting is scheduled to take place as planned. The organization will increase the number of hand-sanitizing stations throughout the convention center, and it is adding a nursing station specifically designated for anyone with flu-like symptoms.
• American College of Cardiology (ACC), Chicago, 3/28/20 - 3/30/20: The organization is working with attendees, faculty, exhibitors, and other stakeholders in affected countries to ensure access to research and education from the meeting, but is otherwise proceeding as planned.
• Endocrine Society (ENDO), San Francisco, 3/28/20 - 3/31/20: ENDO 2020 will take place as scheduled, but this is an evolving situation worldwide. The society will continue to monitor and provide updates on its FAQ page.
• American College of Physicians Internal Medicine (ACP IM), Los Angeles, 4/23/20 - 4/25/20: ACP leadership is closely monitoring the COVID-19 situation and is actively working with the Centers for Disease Control and Prevention (CDC) to ensure authoritative communication of safety updates and recommendations as the situation evolves.
• American Association for Cancer Research (AACR), San Diego, 4/24/20 - 4/29/20: At this time, there is no plan to cancel or postpone any scheduled AACR meetings. The organization is tracking all travel restrictions as well as information and guidance from the CDC and World Health Organization.
• American Academy of Neurology (AAN), Toronto, 4/25/20 - 5/1/20: The group is continuing to closely monitor the situation in Toronto and will provide updates as the situation warrants.

Although wild poliovirus type 3 has not been detected globally for 7 years, the number of wild type 1 cases increased from 33 in 2018 to 173 in 2019. In response, a modified oral vaccine is being developed, according to Stephen Cochi, MD, of the Centers for Disease Control and Prevention’s Center for Global Health.

Several factors, including a Taliban ban on house-to-house vaccination in Afghanistan and a delay of large-scale vaccinations in Pakistan contributed to the surge in polio infections, Dr. Cochi said in a presentation at the February meeting of the CDC’s Advisory Committee on Immunization Practices (ACIP).

In addition, circulating vaccine-derived polioviruses (cVDPV) outbreaks have occurred in multiple countries including sub-Saharan Africa, China, Pakistan, and the Philippines. These outbreaks threaten the success of the bivalent oral polio vaccine introduced in April 2016 in 155 countries, Dr. Cochi said.

Outbreaks tend to occur just outside targeted areas for campaigns, caused by decreasing population immunity, he said.

To help contain the outbreaks, the CDC is fast-tracking development of a novel oral polio vaccine, OPV2, through the Emergency Use Listing. The novel OPV2 (nOPV2) is a genetic modification of the existing OPV2 vaccine designed to improve genetic stability, Dr. Cochi explained. The modifications would “decrease the risk of seeding new cVDPVs and the risk of vaccine-associated paralytic poliomyelitis (VAPP),” he said.

The Emergency Use Listing (EUL) was developed by the World Health Organization in response to the Ebola virus outbreak in 2014-2016 and is the fastest way to obtain regulatory review and approval of drug products, said Dr. Cochi.

A pilot plant has been established in Indonesia, and upon EUL approval, 4-8 million doses of the nOPV2 should be available for use in the second quarter of 2020, he concluded.

Dr. Cochi had no relevant financial conflicts to disclose.

As the first COVID-19 outbreak in the United States emerges in Washington State, the city of Seattle, King County, and Washington State health officials provided the beginnings of a roadmap for how the region will address the rapidly evolving health crisis.

Health officials announced that four new cases were reported over the weekend in King County, Wash. There have now been 10 hospitalizations and 6 COVID-19 deaths at Evergreen Health, Kirkland, Wash. Of the deaths, five were King County residents and one was a resident of Snohomish County. Three patients died on March 1; all were in their 70s or 80s with comorbidities. Two had been residents of the Life Care senior residential facility that is at the center of the Kirkland outbreak. The number of cases in Washington now totals 18, with four cases in Snohomish County and the balance in neighboring King County.

Approximately 29 cases are under investigation with test results pending; a Centers for Disease Control and Prevention (CDC) team is on-site.

Speaking at a news conference March 2, officials sought to strike a balance between giving the community a realistic appraisal of the likely scope of the COVID-19 outbreak and avoiding sparking a panic.

“This is a complex and unprecedented challenge nationally, globally, and locally. The vast majority of the infected have mild or moderate disease and do not need hospitalization,” said Jeffrey Duchin, MD, health officer and chief, Communicable Disease EPI/Immunization Section, Public Health, Seattle and King County, and a professor of infectious diseases at the University of Washington, Seattle. “On the other hand, it’s obvious that this infection can cause very serious disease in people who are older and have underlying health conditions. We expect cases to continue to increase. We are taking the situation extremely seriously; the risk for all of us becoming infected is increasing. ...There is the potential for many to become ill at the same time.”

Among the measures being taken immediately are the purchase by King County of a hotel to house individuals who require isolation and those who are convalescing from the virus. Officials are also placing a number of prefabricated stand-alone housing units on public grounds in Seattle, with the recognition that the area has a large transient and homeless community. The stand-alone units will house homeless individuals who need isolation, treatment, or recuperation but who aren’t ill enough to be hospitalized.

Dr. Duchin said that testing capacity is ramping up rapidly in Washington State: The state lab can now accommodate up to about 200 tests daily, and expects to be able to do up to 1,000 daily soon. The University of Washington’s testing capacity will come online March 2 or 3 as a testing facility with similar initial and future peak testing capacities.

The testing strategy will continue to include very ill individuals with pneumonia or other respiratory illness of unknown etiology, but will also expand to include less ill people. This shift is being made in accordance with a shift in CDC guidelines, because of increased testing capacity, and to provide a better picture of the severity, scope, geography, and timing of the current COVID-19 outbreak in the greater Seattle area.

No school closures or cancellation of gatherings are currently recommended by public health authorities. There are currently no COVID-19 cases in Washington schools. The expectation is that any recommendations regarding closures will be re-evaluated as the outbreak progresses.

Repeatedly, officials asked the general public to employ basic measures such as handwashing and avoidance of touching the face, and to spare masks for the ill and for those who care for them. “The vast majority of people will not have serious illness. In turn we need to do everything we can to help those health care workers. I’m asking the public to do things like save the masks for our health care workers. …We need assets for our front-line health care workers and also for those who may be needing them,” said King County Health Department director Patty Hayes, RN, MN.

Now is also the time for households to initiate basic emergency preparedness measures, such as having adequate food and medication, and to make arrangements for childcare in the event of school closures, said several officials.

“We can decrease the impact on our health care system by reducing our individual risk. We are making individual- and community-level recommendations to limit the spread of disease. These are very similar to what we recommend for influenza,” said Dr. Duchin.

Ettore Palazzo, MD, chief medical and quality officer at EvergreenHealth, gave a sense of how the hospital is coping with being Ground Zero for COVID-19 in the United States. “We have made adjustments for airborne precautions,” he said, including transforming the entire critical care unit to a negative pressure unit. “We have these capabilities in other parts of the hospital as well.” Staff are working hard, but thus far staffing has kept pace with demand, he said, but all are feeling the strain already.

Dr. Duchin made the point that Washington is relatively well equipped to handle the increasingly likely scenario of a large spike in coronavirus cases, since it’s part of the Northwest Healthcare Response Network. The network is planning for sharing resources such as staff, respirators, and intensive care unit beds as circumstances warrant.

“What you just heard illustrates the challenge of this disease,” said Dr. Duchin, summing up. “The public health service and clinical health care delivery systems don’t have the capacity to track down every case in the community. I’m guessing we will see more cases of coronavirus than we see of influenza. At some point we will be shifting from counting every case” to focusing on outbreaks and the critically ill in hospitals, he said.

“We are still trying to contain the outbreak, but we are at the same time pivoting to a more community-based approach,” similar to the approach with influenza, said Dr. Duchin.

As the first COVID-19 outbreak in the United States emerges in Washington State, the city of Seattle, King County, and Washington State health officials provided the beginnings of a roadmap for how the region will address the rapidly evolving health crisis.

Health officials announced that four new cases were reported over the weekend in King County, Wash. There have now been 10 hospitalizations and 6 COVID-19 deaths at Evergreen Health, Kirkland, Wash. Of the deaths, five were King County residents and one was a resident of Snohomish County. Three patients died on March 1; all were in their 70s or 80s with comorbidities. Two had been residents of the Life Care senior residential facility that is at the center of the Kirkland outbreak. The number of cases in Washington now totals 18, with four cases in Snohomish County and the balance in neighboring King County.

Approximately 29 cases are under investigation with test results pending; a Centers for Disease Control and Prevention (CDC) team is on-site.

Speaking at a news conference March 2, officials sought to strike a balance between giving the community a realistic appraisal of the likely scope of the COVID-19 outbreak and avoiding sparking a panic.

“This is a complex and unprecedented challenge nationally, globally, and locally. The vast majority of the infected have mild or moderate disease and do not need hospitalization,” said Jeffrey Duchin, MD, health officer and chief, Communicable Disease EPI/Immunization Section, Public Health, Seattle and King County, and a professor of infectious diseases at the University of Washington, Seattle. “On the other hand, it’s obvious that this infection can cause very serious disease in people who are older and have underlying health conditions. We expect cases to continue to increase. We are taking the situation extremely seriously; the risk for all of us becoming infected is increasing. ...There is the potential for many to become ill at the same time.”

Among the measures being taken immediately are the purchase by King County of a hotel to house individuals who require isolation and those who are convalescing from the virus. Officials are also placing a number of prefabricated stand-alone housing units on public grounds in Seattle, with the recognition that the area has a large transient and homeless community. The stand-alone units will house homeless individuals who need isolation, treatment, or recuperation but who aren’t ill enough to be hospitalized.

Dr. Duchin said that testing capacity is ramping up rapidly in Washington State: The state lab can now accommodate up to about 200 tests daily, and expects to be able to do up to 1,000 daily soon. The University of Washington’s testing capacity will come online March 2 or 3 as a testing facility with similar initial and future peak testing capacities.

The testing strategy will continue to include very ill individuals with pneumonia or other respiratory illness of unknown etiology, but will also expand to include less ill people. This shift is being made in accordance with a shift in CDC guidelines, because of increased testing capacity, and to provide a better picture of the severity, scope, geography, and timing of the current COVID-19 outbreak in the greater Seattle area.

No school closures or cancellation of gatherings are currently recommended by public health authorities. There are currently no COVID-19 cases in Washington schools. The expectation is that any recommendations regarding closures will be re-evaluated as the outbreak progresses.

Repeatedly, officials asked the general public to employ basic measures such as handwashing and avoidance of touching the face, and to spare masks for the ill and for those who care for them. “The vast majority of people will not have serious illness. In turn we need to do everything we can to help those health care workers. I’m asking the public to do things like save the masks for our health care workers. …We need assets for our front-line health care workers and also for those who may be needing them,” said King County Health Department director Patty Hayes, RN, MN.

ORLANDO – For critically ill, mechanically ventilated patients, a strategy of no sedation resulted in a mortality rate that was not significantly different from a strategy of light sedation with interruption, according to results of a multicenter, randomized trial.

The lack of sedation did significantly improve certain secondary endpoints, including a reduced number of thromboembolic events and preservation of physical function, according to Palle Toft, PhD, DMSc, of Odense (Denmark) University Hospital.

However, the 90-day mortality rate was 42.4% in the no-sedation group versus 37.0% in the sedation group in the NONSEDA study, which was intended to test the hypothesis that mortality would be lower in the no-sedation group.

That 5.4 percentage point difference between arms in NONSEDA was not statistically significant (P = .65) in results of the study, presented at the Critical Care Congress sponsored by the Society of Critical Care Medicine and concurrently published in the New England Journal of Medicine.

Yet that mortality trend is in the “opposite direction” of an earlier, single-center trial by Dr. Toft and colleagues, noted Claude Guérin, MD, PhD, in a related editorial that also appeared in the journal. In that earlier study, the reported hospital mortality rates were 36% for no sedation and 47% for sedation with daily interruption.

“The results from this trial [NONSEDA] are important because they arouse concern about omitting sedation in mechanically ventilated patients and reinforce the need to monitor sedation clinically, with the aim of discontinuing it as early as possible or at least interrupting it daily,” Dr. Guérin wrote in his editorial.

That said, the earlier, single-center trial was not statistically powered to show between-group differences in mortality, Dr. Toft and coauthors wrote in their journal article.

In his presentation, Dr. Toft emphasized that light sedation with a wake-up trial was “comparable” with no sedation with regard to mortality.

“I think my main message is that we have to individualize patient treatment,” Dr. Toft told attendees at a late-breaking literature session. “Many patients would benefit from nonsedation, and some would benefit by light sedation with a daily wake-up trial. We have to respect patient autonomy, and try to establish a two-way communication with patients in 2020.”

Sandra L. Kane-Gill, PharmD, treasurer of SCCM and assistant professor of pharmacy and therapeutics at the University of Pittsburgh, said that current SCCM guidelines recommend using light sedation in critically ill, mechanically ventilated adults.

“I think we should stay consistent with what the guidelines are saying,” Dr. Kane-Gill said in an interview. “How you do that may vary, but targeting light sedation is consistent with what the evidence is suggesting in those guidelines.”

The depth of sedation between the no-sedation group in the light sedation group in the present study was not as great as the investigators had anticipated, which may explain the lack of statistically significant difference in mortality, according to Dr. Kane-Gill.

According to the report, 38.4% of patients in the no-sedation group received medication for sedation during their ICU stay, while Richmond Agitation and Sedation Scores increased in both groups, indicating a more alert state in both groups.

The multicenter NONSEDA trial included 700 mechanically ventilated ICU patients randomized either to no sedation or to light sedation, such that the patient was arousable, with daily interruption.

Previous studies have shown that daily interruption of sedation reduced mechanical ventilation duration, ICU stay length, and mortality in comparison with no interruption, the investigators noted.

While mortality at 90 days did not differ significantly between the no-sedation and light-sedation approaches, no sedation reduced thromboembolic events, Dr. Toft said at the meeting. The number of thrombolic events within 90 days was 10 (5%) in the sedation group and 1 (0.5%) in the no-sedation group (P less than .05), according to the reported data.

Likewise, several measures of physical function significantly improved in an a prior defined subgroup of 200 patients, he said. Those measures included hand grip at extubation and ICU discharge, as well as scores on the Barthel Index for Activities of Daily Living.

Nonsedation might improve kidney function, based on other reported outcomes of the study, Dr. Toft said. The number of coma- and delirium-free days was 3.0 in the no-sedation group versus 1.0 in the sedation group (P less than .01), he added.

The benefits of no sedation may extend beyond objective changes in health outcomes, according to Dr. Toft. “The patients are able to communicate with the staff, they might be able to enjoy food, in the evening they can look at the television instead of being sedated – and they can be mobilized and they can write their opinion about the treatments to the doctor, and in this way, you have two-way communication,” he explained in his presentation.

Dr. Toft reported that he had no financial relationships to disclose.

The first death in the United States from the novel coronavirus (COVID-19) was a Washington state man in his 50s who had underlying health conditions, state health officials announced on Feb 29. At the same time, officials there are investigating a possible COVID-19 outbreak at a long-term care facility.

Washington state officials reported two other presumptive positive cases of COVID-19, both of whom are associated with LifeCare of Kirkland, Washington. One is a woman in her 70s who is a resident at the facility and the other is a woman in her 40s who is a health care worker at the facility.

Additionally, many residents and staff members at the facility have reported respiratory symptoms, according to Jeff Duchin, MD, health officer for public health in Seattle and King County. Among the more than 100 residents at the facility, 27 have respiratory symptoms; while among the 180 staff members, 25 have reported symptoms.

Overall, these reports bring the total number of U.S. COVID-19 cases detected by the public health system to 22, though that number is expected to climb as these investigations continue.

The general risk to the American public is still low, including residents in long-term care facilities, Nancy Messonnier, MD, director of the National Center for Immunization and Respiratory Diseases at the Centers for Disease Control and Prevention, said during the Feb. 29 press briefing. Older people are are higher risk, however, and long-term care facilities should emphasize handwashing and the early identification of individuals with symptoms.

Dr. Duchin added that health care workers who are sick should stay home and that visitors should be screened for symptoms, the same advice offered to limit the spread of influenza at long-term care facilities.

The CDC briefing comes after President Trump held his own press conference at the White House where he identified the person who had died as being a woman in her 50s who was medically at risk.

During that press conference, Anthony S. Fauci, MD, director of the National Institute of Allergy and Infectious Diseases, said that the current pattern of disease with COVID-19 suggests that 75%-80% of patients will have mild illness and recover, while 15%-20% will require advanced medical care.

For the most part, the more serious cases will occur in those who are elderly or have underlying medical conditions. There is “no indication” that individuals who recover from the virus are becoming re-infected, Dr. Fauci said.

The administration also announced a series of actions aimed at slowing the spread of the virus and responding to it. On March 2, President Trump will meet with leaders in the pharmaceutical industry at the White House to discuss vaccine development. The administration is also working to ensure an adequate supply of face masks. Vice President Mike Pence said there are currently more than 40 million masks available, but that the administration has received promises of 35 million more masks per month from manufacturers. Access to masks will be prioritized for high-risk health care workers, Vice President Pence said. “The average American does not need to go out and buy a mask,” he added.

Additionally, Vice President Pence announced new travel restrictions with Iran that would bar entry to the United States for any foreign national who visited Iran in the last 14 days. The federal government is also advising Americans not to travel to the regions in Italy and South Korea that have been most affected by COVID-19. The government is also working with officials in Italy and South Korea to conduct medical screening of anyone coming into the United States from those countries.

At the same time, officials there are investigating a possible COVID-19 outbreak at a long-term care facility.

Washington state officials reported two other presumptive positive cases of COVID-19, both of whom are associated with LifeCare of Kirkland, Washington. One is a woman in her 70s who is a resident at the facility and the other is a woman in her 40s who is a health care worker at the facility.

Additionally, many residents and staff members at the facility have reported respiratory symptoms, according to Jeff Duchin, MD, health officer for public health in Seattle and King County. Among the more than 100 residents at the facility, 27 have respiratory symptoms; while among the 180 staff members, 25 have reported symptoms.

Overall, these reports bring the total number of U.S. COVID-19 cases detected by the public health system to 22, though that number is expected to climb as these investigations continue.

The general risk to the American public is still low, including residents in long-term care facilities, Nancy Messonnier, MD, director of the National Center for Immunization and Respiratory Diseases at the Centers for Disease Control and Prevention, said during the Feb. 29 press briefing. Older people are are higher risk, however, and long-term care facilities should emphasize handwashing and the early identification of individuals with symptoms.

Dr. Duchin added that health care workers who are sick should stay home and that visitors should be screened for symptoms, the same advice offered to limit the spread of influenza at long-term care facilities.

The CDC briefing comes after President Trump held his own press conference at the White House where he identified the person who had died as being a woman in her 50s who was medically at risk.

During that press conference, Anthony S. Fauci, MD, director of the National Institute of Allergy and Infectious Diseases, said that the current pattern of disease with COVID-19 suggests that 75%-80% of patients will have mild illness and recover, while 15%-20% will require advanced medical care.

For the most part, the more serious cases will occur in those who are elderly or have underlying medical conditions. There is “no indication” that individuals who recover from the virus are becoming re-infected, Dr. Fauci said.

The administration also announced a series of actions aimed at slowing the spread of the virus and responding to it. On March 2, President Trump will meet with leaders in the pharmaceutical industry at the White House to discuss vaccine development. The administration is also working to ensure an adequate supply of face masks. Vice President Mike Pence said there are currently more than 40 million masks available, but that the administration has received promises of 35 million more masks per month from manufacturers. Access to masks will be prioritized for high-risk health care workers, Vice President Pence said. “The average American does not need to go out and buy a mask,” he added.

Additionally, Vice President Pence announced new travel restrictions with Iran that would bar entry to the United States for any foreign national who visited Iran in the last 14 days. The federal government is also advising Americans not to travel to the regions in Italy and South Korea that have been most affected by COVID-19. The government is also working with officials in Italy and South Korea to conduct medical screening of anyone coming into the United States from those countries.

In a telebriefing on the COVID-19 outbreak, Nancy Messonnier, MD, director of the National Center for Immunization and Respiratory Diseases at the Centers for Disease Control and Prevention announced that the agency has updated the definition of “Person Under Investigation,” or PUI, for the disease.

The definition has been revised “to meet the needs of this rapidly evolving situation,” she said. The new PUI definition includes travel to more geographic areas to reflect this past week’s marked uptick in coronavirus activity in Italy and Iran. In addition to these countries and China, recent travel to Japan or South Korea also constitutes an epidemiologic risk factor which, in conjunction with clinical features, warrant an individual being classified as a PUI. These five countries each now have widespread person-to-person transmission of the virus.

Dr. Messonnier left open the possibility that the PUI definition would continue to evolve if such transmission within communities becomes more common. Asked whether the small number of U.S. cases thus might be an artifact of low test volumes, she said, “We aggressively controlled our borders to slow the spread. This was an intentional U.S. strategy. The CDC has always had the capacity to test rapidly from the time the sequence was available. ...We have been testing aggressively.”

The original PUI definition, she explained, emphasized individuals with fever, cough, or trouble breathing who had traveled recently from areas with COVID-19 activity, in particular China’s Hubei province. “We have been most focused on symptomatic people who are closely linked to, or who had, travel history, but our criteria also allow for clinical discretion,” she said. “There is no substitute for an astute clinician on the front lines of patient care.”

The first COVID-19 case from person-to-person spread was reported on Feb. 27. “At this time, we don’t know how or where this person became infected,” said Dr. Messonnier, although investigations are still underway. She responded to a question about whether the CDC delayed allowing COVID-19 testing for the patient for several days, as was reported in some media accounts. “According to CDC records, the first call we got was Feb. 23,” when public health officials in California reported a severely ill person with no travel abroad and no known contacts with individuals that would trigger suspicions for coronavirus. The CDC recommended COVID-19 testing on that day, she said.

Dr. Messonnier declined to answer questions about a whistleblower report alleging improper training and inadequate protective measures for Department of Health & Human Services workers at the quarantine center at Travis Air Force Base, Calif.

Dr. Messonnier said that the CDC has been working closely with the Food and Drug Administration to address problems with the COVID-19 test kits that were unusable because of a large number of indeterminate results. The two agencies together have determined that of the three reactions that were initially deemed necessary for a definitive COVID-19 diagnosis, just two are sufficient, so new kits that omit the problematic chemical are being manufactured and distributed.

These new kits are rapidly being made available; the goal, said Dr. Messonnier, is to have to state and local public health departments equipped with test kits by about March 7.

As local tests become available, the most updated information will be coming from state and local public health departments, she stressed, adding that the CDC would continue to update case counts on Monday, Wednesday, and Friday of each week. Procedures are being developed for the management of patients presumed to have COVID-19, where local health departments see positive tests but the mandatory CDC confirmatory test hasn’t been completed.

While new cases emerge across Europe and Asia, China’s earlier COVID-19 explosion seems to be slowing. “It’s really good news that the case counts in China are decreasing,” both for the well-being of that country’s citizens, and as a sign of the disease’s potential global effects, said Dr. Messonnier. She added that epidemiologists and mathematical modelers are parsing case fatality rates as well.
