Mumps: Sometimes forgotten but not gone
The 7-year-old boy sat at the edge of a stretcher in the emergency department, looking miserable, as his mother recounted his symptoms to a senior resident physician on duty. Low-grade fever, fatigue, and myalgias prompted rapid SARS-CoV-2 testing at his school. That test, as well as a repeat test at the pediatrician’s office, were negative. A triage protocol in the emergency department prompted a third test, which was also negative.
“Everyone has told me that it’s likely just a different virus,” the mother said. “But then his cheek started to swell. Have you ever seen anything like this?”
The boy turned his head, revealing a diffuse swelling that extended down his right cheek to the angle of his jaw.
“Only in textbooks,” the resident physician responded.
It is a credit to our national immunization program that most practicing clinicians have never actually seen a case of mumps. Before vaccination was introduced in 1967, infection in childhood was nearly universal. Unilateral or bilateral tender swelling of the parotid gland is the typical clinical finding. Low-grade fever, myalgias, decreased appetite, malaise, and headache may precede parotid swelling in some patients. Other patients infected with mumps may have only respiratory symptoms, and some may have no symptoms at all.
Two doses of measles-mumps-rubella vaccine have been recommended for children in the United States since 1989, with the first dose administered at 12-15 months of age. According to data collected through the National Immunization Survey, more than 92% of children in the United States receive at least one dose of measles-mumps-rubella vaccine by 24 months of age. The vaccine is immunogenic, with 94% of recipients developing measurable mumps antibody (range, 89%-97%). The vaccine has been a public health success: Overall, mumps cases declined more than 99% between 1967 and 2005.
But in the mid-2000s, mumps cases started to rise again, with more than 28,000 reported between 2007 and 2019. Annual cases ranged from 229 to 6,369 and while large, localized outbreaks have contributed to peak years, mumps has been reported from all 50 states and the District of Columbia. According to a recently published paper in Pediatrics, nearly a third of these cases occurred in children <18 years of age and most had been appropriately immunized for age.
Of the 9,172 cases reported in children, 5,461 or 60% occurred between 2015 and 2019. Of these, 55% were in boys. While cases occurred in children of all ages, 54% were in children 11-17 years of age, and 33% were in children 5-10 years of age. Non-Hispanic Asian and/or Pacific Islander children accounted for 38% of cases. Only 2% of cases were associated with international travel and were presumed to have been acquired outside the United States
The reason for the increase in mumps cases in recent years is not well understood. Outbreaks in fully immunized college students have prompted concern about poor B-cell memory after vaccination resulting in waning immunity over time. In the past, antibodies against mumps were boosted by exposure to wild-type mumps virus but such exposures have become fortunately rare for most of us. Cases in recently immunized children suggest there is more to the story. Notably, there is a mismatch between the genotype A mumps virus contained in the current MMR and MMRV vaccines and the genotype G virus currently circulating in the United States.
With the onset of the pandemic and implementation of mitigation measures to prevent the spread of COVID-19, circulation of some common respiratory viruses, including respiratory syncytial virus and influenza, was sharply curtailed. Mumps continued to circulate, albeit at reduced levels, with 616 cases reported in 2020. In 2021, 30 states and jurisdictions reported 139 cases through Dec. 1.
Clinicians should suspect mumps in all cases of parotitis, regardless of an individual’s age, vaccination status, or travel history. Laboratory testing is required to distinguish mumps from other infectious and noninfectious causes of parotitis. Infectious causes include gram-positive and gram-negative bacterial infection, as well as other viral infections, including Epstein-Barr virus, coxsackie viruses, parainfluenza, and rarely, influenza. Case reports also describe parotitis coincident with SARS-CoV-2 infection.
When parotitis has been present for 3 days or less, a buccal swab for RT-PCR should be obtained, massaging the parotid gland for 30 seconds before specimen collection. When parotitis has been present for >3 days, a mumps Immunoglobulin M serum antibody should be collected in addition to the buccal swab PCR. A negative IgM does not exclude the possibility of infection, especially in immunized individuals. Mumps is a nationally notifiable disease, and all confirmed and suspect cases should be reported to the state or local health department.
Back in the emergency department, the mother was counseled about the potential diagnosis of mumps and the need for her son to isolate at home for 5 days after the onset of the parotid swelling. She was also educated about potential complications of mumps, including orchitis, aseptic meningitis and encephalitis, and hearing loss. Fortunately, complications are less common in individuals who have been immunized, and orchitis rarely occurs in prepubertal boys.
The resident physician also confirmed that other members of the household had been appropriately immunized for age. While the MMR vaccine does not prevent illness in those already infected with mumps and is not indicated as postexposure prophylaxis, providing vaccine to those not already immunized can protect against future exposures. A third dose of MMR vaccine is only indicated in the setting of an outbreak and when specifically recommended by public health authorities for those deemed to be in a high-risk group. Additional information about mumps is available at www.cdc.gov/mumps/hcp.html#report.

Alternative birthing practices increase risk of infection
All three have been associated with sporadic, serious neonatal infections.
The U.S. prevalence of water births – delivering a baby underwater – is currently unknown, but in the United Kingdom the practice is common. According to a 2015 National Health Service maternity survey, approximately 9% of women who underwent vaginal delivery opted for water birth (Arch Dis Child Fetal Neonatal Ed. 2016 Jul;101[4]:F357-65). Both the Royal College of Obstetricians and Gynaecologists and the Royal College of Midwives endorse this practice for healthy women with uncomplicated term pregnancies. According to a 2009 Cochrane Review, immersion during the first phase of labor reduces the use of epidural/spinal analgesia (Cochrane Database Syst Rev. 2009. doi: 10.1002/14651858.CD000111.pub3). The maternal benefits of delivery under water, though, have not been clearly defined.
Legionella pneumophila is an uncommon pathogen in children, but cases of neonatal Legionnaires’ disease have been reported after water birth. Two affected babies born in Arizona in 2016 were successfully treated and survived (MMWR Morb Mortal Wkly Rep. 2017. doi: 10.15585/mmwr.mm6622a4). A baby born in Texas in 2014 died of sepsis and respiratory failure (Emerg Infect Dis. 2015. doi: 10.3201/eid2101.140846). Canadian investigators have reported fatal disseminated herpes simplex virus infection in an infant after water birth; the mother had herpetic whitlow and a recent blister concerning for HSV on her thigh (J Pediatric Infect Dis Soc. 2017 May 16. doi: 10.1093/jpids/pix035).
Admittedly, each of these cases might have been prevented by adherence to recommended infection control practices, and the absolute risk of infection after water birth is unknown and likely to be small. Still, neither the American Academy of Pediatrics nor the American College of Obstetricians and Gynecologists currently recommend the practice. ACOG suggests that “births occur on land, not in water” and has called for well-designed, prospective studies of the maternal and perinatal benefits and risks associated with immersion during labor and delivery (Obstet Gynecol. 2016;128:1198-9).
Placentophagia – consuming the placenta after birth – has been promoted by celebrity moms, including Katherine Heigl and Kourtney Kardashian. Placenta can be cooked, blended raw into a smoothie, or dehydrated and encapsulated.
Proponents of placentophagia claim health benefits of this practice, including improved mood and energy, and increased breast milk production. There are few published data to support these claims. A recent case report suggests the practice has the potential to harm the baby. In June 2017, Oregon public health authorities described a neonate with recurrent episodes of group B streptococcal (GBS) bacteremia. An identical strain of GBS was cultured from capsules containing the mother’s dehydrated placenta – she had consumed six of the capsules daily beginning a few days after the baby’s birth. According to the Morbidity and Mortality Weekly Report communication, “no standards exist for processing placenta for consumption” and the “placenta encapsulation process does not eradicate infectious pathogens per se. … Placenta capsule ingestion should be avoided”(MMWR Morb Mortal Wkly Rep. 2017;66:677-8. doi: 10.15585/mmwr.mm6625a4).
Finally, the ritual practice of umbilical cord nonseverance or lotus birth deserves a mention. In a lotus birth, the umbilical cord is left uncut, allowing the placenta to remain attached to the baby until the cord dries and naturally separates, generally 3-10 days after delivery. Describing a spiritual connection between the baby and the placenta, proponents claim lotus birth promotes bonding and allows for a gentler transition between intra- and extrauterine life.
A review of PubMed turned up no formal studies of this practice, but case reports describe complications such as neonatal idiopathic hepatitis and neonatal sepsis. The Royal College of Obstetricians and Gynaecologists has issued a warning about lotus births, advising that babies be monitored closely for infection. RCOG spokesperson Dr. Patrick O’Brien said in a 2008 statement, “If left for a period of time after the birth, there is a risk of infection in the placenta which can consequently spread to the baby. The placenta is particularly prone to infection as it contains blood. Within a short time after birth, once the umbilical cord has stopped pulsating, the placenta has no circulation and is essentially dead tissue.”
Interestingly, a quick scan of Etsy, the popular e-commerce website, turned up a number of lotus birth kits for sale. These generally contain a decorative cloth bag as well as an herb mix containing lavender and eucalyptus to promote drying and mask the smell of the decomposing placenta.
In contrast, many pediatricians, me included, are not well informed about these practices and don’t routinely ask expectant moms about their plans. I propose that we can advocate for our patients-to-be by learning about these practices so that we can engage in an honest, respectful discussion about potential risks and benefits. For me, for now, the risks outweigh the benefits.
