Prevent the spread of mumps in our community

  • The best way to prevent mumps is to get vaccinated.   The MMR vaccine protects against measles, mumps, and rubella.  See routine and outbreak vaccination recommendations below.
  • 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.

 

Routine MMR Vaccination Recommendations:

  • All children should receive two doses of MMR vaccine. The first dose is typically given at age 12–15 months and the second dose routinely at age 4–6 years.
  • All adults born in 1957 or later should receive at least one dose of MMR vaccine (persons at high risk for exposure to mumps, including college students, health care workers, and international travelers, should receive two doses).

Outbreak MMR Vaccination Recommendations:

Due to the current mumps outbreak in Hawaii, in addition to the routine vaccination recommendations above, persons born in 1957 or later, especially those who live or work in crowded conditions, should receive an additional MMR vaccine dose now:

For persons born in 1957 or later:

Number of previous MMR doses Years since last MMR dose Vaccinate Now
2 10 years or more Yes
1 5 years or more Yes
None or unknown Yes

Before vaccines were available, nearly everyone was infected with mumps during childhood.  The majority of people born before 1957 are likely to have been infected with mumps and therefore are presumed to be protected.  Persons born before 1957 who are unsure if they had mumps disease previously should talk to their healthcare provider about vaccination.

In general, although it is not ideal, receiving extra doses of vaccine poses no medical problem.

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