The Hawai‘i Department of Health (DOH) has identified a new travel-related case of dengue virus on Oʻahu, bringing the total number of dengue cases to 13 in the state in 2025 (one on Maui, 12 on Oʻahu). The affected individual in this current case was exposed to the virus while traveling in a region where dengue is common and is not connected to prior cases.

Dengue virus is transmitted from an infected person to a mosquito, then to another person. While Hawai‘i is home to the mosquitoes that can carry dengue, the disease is not endemic (established) in the state and cases are currently limited to travelers.

Symptoms of dengue can range from mild to severe and include fever, nausea, vomiting, rash and body aches. Symptoms typically last two to seven days and while severe illness can occur, most people recover within a week.
