According to HawaiiNewsNow, the State Health Department has confirmed another case of Hepatitis A in a State Department of Transportation employee, raising the number of confirmed cases to 135.

The Department of Health said on Monday that it is getting closer to finding out what is causing the outbreak.

“The indications are that whatever it is, this is not a fresh product it’s probably something that keeps for a while so frozen or dried or something,” State epidemiologist, Dr. Sarah Park said.
