Six confirmed and fourteen suspect cases of mumps in Cambridge residents have been reported to the Massachusetts Department of Public Health (MDPH) since mid-February. All have been students at a large Boston-area university. The six confirmed cases have documentation of two doses of measles-mumps-rubella (MMR) vaccine, and the majority of the suspected cases are believed to have had two doses of MMR. In addition to the cases in Massachusetts, mumps has been confirmed recently in a college in Manchester, New Hampshire. In the midwestern United States (Indiana, Kentucky, Iowa) there have been several mumps outbreaks at colleges and universities over the past few months, including in 2016. The beginning of the Spring Break season may have an impact on further and wider transmission. MDPH urges providers to consider a diagnosis of mumps in anyone presenting with typical symptoms of mumps, regardless of vaccination history.
1. Consider a diagnosis of mumps in those with mumps symptoms, regardless of vaccination history.
2. Use droplet and standard precautions to prevent transmission.
3. Obtain appropriate clinical specimens for testing at the Massachusetts State Public Health Laboratory. A buccal swab is preferred for patients with recent onsets (within five days of onset of swelling)
4. Isolate suspected and confirmed mumps cases for five days after onset of swelling.
5. Report suspected cases to MDPH at 617-983-6800. Cases diagnosed in Boston should be reported to the Boston Public Health Commission at 617-534-5611.
6. Vaccinate those without evidence of immunity to mumps and reach out to those with medical and religious exemptions
