Prevent the spread of mumps in our community

  • Ensure 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 routinely at 4–6 years of age.  However, due to the continued circulation of mumps in Hawaii, children between 1–4 years of age should receive their second dose now (a minimum of 4 weeks after the first dose).
    • All adults born in or after 1957, without evidence of immunity to mumps, who cannot verify previous MMR vaccination, should receive one MMR dose.
    • Individuals with only one documented MMR dose, are strongly encouraged to consider receiving a second MMR vaccine dose.

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

  • 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.
