Hawaii Reports New Travel-Related Dengue Case on Oahu
The Hawaii Department of Health (DOH) has confirmed one new travel-related case of dengue virus on Oahu, marking the state’s total to eight cases for 2026. The affected individual contracted the virus while traveling in a region known for dengue prevalence; however, no links to previous cases in Hawaii have been established.
DOH teams are actively performing inspections and implementing mosquito control in the affected area. While the risk of local transmission remains low, recent heavy rains have prompted reminders for residents to eliminate standing water to reduce mosquito breeding.
Dengue virus spreads from infected individuals to mosquitoes and then to others. Although Hawaii has mosquitoes capable of transmitting dengue, the disease is not endemic to the state. All reported cases this year have been associated with travel to Pacific Island countries.
Dengue poses a year-round risk in several tropical regions, including parts of Central and South America, Asia, Africa, and the Caribbean. Some countries have experienced spikes in dengue cases, including Bangladesh, Malaysia, and Vietnam.
Travelers to dengue-prone areas are encouraged to review updated travel information weeks before their trip and take precautions, such as using EPA-registered insect repellent, wearing long-sleeved clothing, and sleeping in air-conditioned or screened rooms. Returning travelers should avoid mosquito bites for three weeks and consult a medical professional if symptoms appear within two weeks.
Symptoms of dengue may range from mild to severe and can include fever, nausea, vomiting, rash, and body aches, generally lasting between two to seven days. Most recover within a week, but those experiencing symptoms after travel should seek medical advice. For further mosquito control information, visit the Vector Control Branch website.
