The Department of Health (DOH) reports one new Oʻahu travel-related dengue virus case in an individual who traveled to a region where dengue is known to be spread. DOH teams were deployed for inspection and mosquito control in the affected area.

In 2024, nine travel-related dengue cases have been identified in the state (one on Kauaʻi, two on Maui, six on Oʻahu).

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.

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 (established) here in the state and cases are currently only seen in travelers.

In areas of suspected or confirmed dengue, Hawai‘i DOH personnel (Vector Control Branch) conduct inspections and mosquito-reducing activities. Reducing mosquito populations reduces the chances of dengue being transmitted to other people.
