4 more mumps cases on Big Island

The state Department of Health reported four new cases of mumps on the Big Island in its weekly update.

Since June 30, 12 cases have been confirmed on the island as of Thursday.

Cases are increasing statewide; about half are children and half adults.

Among vaccinated people, 12 percent still get mumps if exposed, but effects are less severe.

A total of 332 cases have been confirmed statewide: 290 on Oahu, 29 on Kauai, 12 on Hawaii Island and one on Maui.

Health officials advise unvaccinated adults born after 1957 to get an MMR vaccination (measles, mumps, rubella).

Children typically get second doses at age 4-6 but should get them now, experts advise.

The state advises not to go to work, school or travel once exposed.
