The number of dengue cases on Hawaii island is now up to 163, up from 160 on Wednesday, according to the state Department of Health.

Of the confirmed cases, all have recovered or are recovering, and only four are considered infectious, the Health Department said in a release Friday.

Of those infected, 34 have been children and 145 have been residents. A state lab on Oahu tests dengue fever samples on weekdays, and so far, 644 reported potential cases have been excluded through testing or investigative work.

The state has conducted 313 mosquito abatement sprayings since the beginning of the outbreak in September.

Dengue is not endemic to Hawaii, but is occasionally transported from endemic areas by infected travelers.

The Big Island and the rest of Hawaii remain safe for visitors and residents, the Health Department said.
