The Hawai‘i Department of Health has recently confirmed another travel-related case of dengue fever on Oʻahu. This case marks the second in the state for 2025, and it stems from an individual exposed to the disease while traveling in a region where dengue is prevalent. As travel increases with the decline of pandemic concerns, the re-emergence of such global health risks can spread quickly across borders.
Health officials have jumped into action, dispatching DOH teams to conduct thorough inspections and apply mosquito control efforts in areas of concern. While they run a tight ship, the public's role in this health drama is also critical. People in and around the affected zones are urged to take up best practices to prevent further spread of the virus. These include standard precautions like use of EPA-approved repellent, proper attire, and ensuring sleeping areas are guarded against mosquitoes, be it via air-conditioning, screens, or nets.
Dengue fever is a mosquito-borne disease that can have serious effects. While not endemic to Hawai‘i, the state has reported cases, including 16 last year, with the disease brought back by travelers returning from regions where it is more prevalent, according to the Hawaii Department of Health.
If you’ve recently returned from a region on the global dengue hotspot list, it’s advised to use bug repellent for three weeks after your arrival. If you experience symptoms such as fever, nausea, or rash, the Department of Health recommends contacting your healthcare provider. Dengue can become severe, so early attention is important.
The Department of Health's Vector Control Branch is implementing mosquito-reduction strategies in affected areas to help prevent local dengue outbreaks. At home, actions like emptying containers that can collect standing water can be effective in reducing mosquito breeding sites. For more information, the DOH advises visiting the Disease Outbreak Control Division and Vector Control Branch websites. Reducing mosquito populations can contribute to a healthier Hawai‘i.
