The Hawai‘i Department of Health (DOH) identified a new case of travel-related dengue virus on Oʻahu. This is the first reported case of 2025. The affected traveler was exposed in a country where dengue is common.

DOH teams were deployed for inspection and mosquito control in the affected area.

Dengue virus is spread from infected person to mosquito to person. While Hawai‘i is home to the type of mosquitoes that can carry dengue, the disease is not endemic here in the state and cases are currently only seen in travelers.

Symptoms of dengue typically may be mild or severe and include fever, nausea, vomiting, rash and body aches. Symptoms typically last two to seven days and although severe and even life-threatening illness can occur, most people recover after about a week.
