The Hawai‘i Department of Health (DOH) has reported a new travel-related dengue virus case on Maui. This brings the total number of cases in the state to 14 for 2024, with one case on Kauaʻi, four on Maui, and nine on Oʻahu. The traveler was exposed to the virus in a country where dengue is prevalent.
In response, DOH teams have been deployed for inspection and mosquito control in the affected area. The community is encouraged to reduce the risk of local transmission by following recommended practices.
"Dengue virus is spread from infected person to mosquito to person," stated the DOH. While Hawai‘i hosts mosquitoes capable of carrying dengue, the disease is not endemic in the state and is currently seen only in travelers. Various regions worldwide are experiencing increased dengue activity.
Dengue outbreaks occur globally, including Central and South America, Asia (such as the Republic of the Philippines), the Middle East, Africa, some Pacific Islands like American Samoa, Federated States of Micronesia, Republic of Marshall Islands, Republic of Palau, and popular tourist spots in the Caribbean like Puerto Rico.
Travelers to areas with dengue risk should take precautions advised by the Centers for Disease Control and Prevention (CDC). These include using EPA-registered insect repellent, wearing long sleeves and pants outdoors, and sleeping in air-conditioned rooms or under treated bed nets. It is important to review travel information four to six weeks before traveling for updated guidance on dengue prevention.
Returning travelers from areas at risk should prevent mosquito bites for three weeks. If symptoms such as fever, nausea, vomiting, rash or body aches develop within two weeks after return, medical evaluation should be sought.
The Hawai‘i DOH's Vector Control Branch conducts inspections and activities to reduce mosquito populations in suspected or confirmed dengue areas. Eliminating breeding sites helps prevent transmission. Common breeding sites include small containers with standing water around homes.
Mosquitoes can breed in minimal amounts of standing water found in items like buckets or rain barrels. Pouring out such water removes potential breeding grounds.
