This Health Alert Network (HAN) Advisory is to remind primary health care providers in Delaware that mumps outbreaks can still occur in communities of people who previously had one or two doses of MMR vaccine. This is particularly common in close-contact settings. Vigilance is needed to identify mumps cases early and prevent outbreaks.
High vaccination rates among Delaware children has resulted in only very few cases of mumps reported each year (on average 0-3 unconnected cases). However, 20 cases were reported in 2018, most of which were linked to an outbreak involving attendees of a multicultural dance in New Castle County; three cases (two confirmed and one probable) were reported in 2019. The Delaware Division of Public Health (DPH) is currently investigating an outbreak of mumps cases in New Castle County, Delaware. As of March 3, 2020, nine cases have been reported (seven confirmed, two probable), all in school-age children.
Providers are strongly urged to:
Buccal swabs and serum serologies for both IgM and IgG are the available options to diagnose mumps. Buccal swabs are the preferred test as serology may not differentiate recent mumps exposure or previous vaccinations.
Mumps is a viral illness acquired through respiratory droplets. The incubation period ranges from 12-25 days. The prodromal symptoms are nonspecific, and include myalgia, anorexia, malaise, headache, and low-grade fever. Parotitis is the most common manifestation. Contagiousness is similar to that of influenza and infected individuals are most contagious in the few days prior to and after parotitis. Transmission also likely occurs from persons with asymptomatic infections and from persons with prodromal symptoms. The most common complication in the post-vaccine era is orchitis. Less common side effects include mastitis, oophoritis, pancreatitis, deafness, meningitis, and encephalitis.
A person with two doses of MMR vaccine has about an 88% reduction in risk for mumps; a person with one dose has a 78% reduction in risk for mumps. In addition, disease symptoms are milder and complications are less frequent in vaccinated people. Also, high vaccination coverage helps to limit the size, duration, and spread of mumps outbreaks. Indications as listed below:
MMR vaccine is not recommended for use as post-exposure prophylaxis.
