The Hawai'i Department of Health has recently confirmed another case of the dengue virus on Oʻahu, marking this as the 10th case in 2025 linked to travel. According to Hawai‘i Department of Health (DOH) official reports, the latest patient contracted the virus while in a region known for dengue presence. With this new development, the state's total cases comprise one on Maui and the remaining nine on Oʻahu.
In response, DOH teams have begun inspections and mosquito control efforts in areas potentially affected. While dengue is not currently endemic in Hawaiʻi, the public is advised to maintain preventive measures. For those traveling to regions with higher dengue risk—including parts of Central and South America, Asia, the Middle East, Africa, and the Caribbean—the CDC outlines recommended precautions to reduce the chance of infection.
The Department of Health recommends several preventive measures for those at risk of dengue virus exposure, including the use of EPA-registered insect repellents, wearing long protective clothing, and ensuring mosquito safeguards in accommodations. Travelers returning from dengue-endemic regions are advised to avoid mosquito bites for at least three weeks. Individuals experiencing symptoms such as fever, rash, or body aches within two weeks of returning should consult a healthcare provider. Suspected dengue cases should be reported to the Disease Reporting Line at 808-586-4586.
