Hawaii News Now reports the outbreak of Hepatitis A in the islands has now sickened 135 people, the state Health Department said Wednesday.

All cases have been in adults, and 39 have required hospitalization.

The total number of cases statewide is up by 42 people since last week. The onset of illness ranges from June 12 to July 24.

This is by far the largest outbreak of Hepatitis A in the islands in decades. State health officials said the outbreak appears to be focused on Oahu, but its source remains unclear. Seven of those who have been sickened live on the Neighbor Islands; one visitor has returned to the mainland.
