The Hawai‘i Department of Health (DOH) has reported a new case of travel-related dengue virus on Oʻahu. This brings the total number of cases identified in the state to 15 for the year 2024, with one case on Kauaʻi, four on Maui, and ten on Oʻahu. The affected individuals contracted the virus while traveling in regions where dengue is prevalent.
In response to this development, DOH teams have been deployed for inspection and mosquito control efforts in the impacted area. The department urges residents to assist in minimizing local transmission risks by following recommended practices.
"Dengue virus is spread from infected person to mosquito to person," explained a spokesperson from DOH. Although Hawai‘i hosts mosquitoes capable of carrying dengue, the disease is not endemic to the state and currently appears only among travelers.
Dengue outbreaks are common in various parts of the world, including Central and South America, Asia, parts of Africa and the Middle East, some Pacific Islands like American Samoa and Micronesia, as well as tourist destinations such as Puerto Rico.
Travelers heading to or returning from these areas should be cautious. "Currently, the Centers for Disease Control and Prevention (CDC) advises travelers to practice usual precautions when traveling to areas of dengue risk," noted DOH. These precautions include using EPA-registered insect repellent, wearing protective clothing outdoors, and ensuring sleeping environments are mosquito-free.
Those returning from regions with dengue risk should avoid mosquito bites for three weeks post-travel. If symptoms appear within two weeks after returning home—such as fever or rash—medical evaluation is advised.
Dengue symptoms range from mild to severe: fever, nausea, vomiting, rash, body aches lasting up to a week. While most recover fully after about seven days without complications, severe cases can occur.
The Hawai‘i DOH's Vector Control Branch actively inspects suspected areas and implements mosquito-reducing measures when necessary. In unaffected zones, residents are encouraged to eliminate potential breeding sites around their homes by removing standing water found in containers like buckets or planters.
