Department of Health investigating mumps cases

The Hawaii State Department of Health (DOH) continues to investigate an increasing number of cases of mumps infection statewide.  The disease has been confirmed in children and adults, both vaccinated and unvaccinated.

As of May 25, 2017:

Number of confirmed cases of mumps for 2017:                 58

As the numbers of cases investigated related to the initial two clusters increases, the identification of new isolated (i.e., no travel and no relation to those clusters) cases grows.  To date, none of the infected individuals have required hospitalization for mumps.

Prevent the spread of mumps in our community by:

  • Ensuring your family is fully vaccinated with the MMR vaccine.
    • All children should receive two doses of the MMR vaccine which protects against three diseases: measles, mumps, and rubella. The first dose is given at age 12–15 months and the second dose at 4–6 years of age.
    • All adults born in or after 1957 should also have documentation of vaccination, unless they have had a blood test showing they are immune to mumps. Certain adults at higher risk of exposure to mumps may need a second dose of MMR vaccine.
  • Patients suspected or diagnosed with mumps should self-isolate and avoid going out and exposing others for 9 days after onset of parotitis (swelling of the salivary glands).
  • People who have been exposed to mumps and are not vaccinated should not attend school, work or travel from day 12 through day 25 after exposure.

Healthcare providers should report any suspected cases of mumps to DOH immediately by calling the disease reporting line at (808) 586-4586.
