The Hawai‘i Department of Health (DOH) has reported a new travel-related case of the dengue virus on Maui, marking the 14th such case in the state for 2024. The cases include one on Kauaʻi, four on Maui, and nine on Oʻahu. The affected individual was exposed to the virus in a country where dengue is prevalent.
In response, DOH teams have been dispatched for inspection and mosquito control in the area. The community is encouraged to follow best practices to reduce any risk of local transmission.
Dengue virus spreads from an infected person to a mosquito and then to another person. While mosquitoes capable of carrying dengue are present in Hawai‘i, the disease is not endemic to the state and current cases are linked to travelers. Many regions globally are experiencing heightened dengue activity.
Outbreaks occur in parts of Central and South America, Asia including the Republic of the Philippines, the Middle East, Africa, Pacific Islands like American Samoa, Federated States of Micronesia, Republic of Marshall Islands, Republic of Palau, and popular tourist destinations in the Caribbean such as Puerto Rico.
Travelers to these areas are at risk for infection. The Centers for Disease Control and Prevention (CDC) recommends using EPA-registered insect repellent, wearing long sleeves and pants outdoors, and sleeping with air conditioning or window screens. Countries may report increased cases; thus it is advised to review travel information four to six weeks before departure for updated guidance on dengue risk and prevention.
Upon returning from an area with dengue risk, travelers should prevent mosquito bites for three weeks. If symptoms develop within two weeks after return—such as fever, nausea, vomiting, rash or body aches—medical evaluation is recommended.
Symptoms can range from mild to severe but typically last two to seven days. Most individuals recover within about a week; however severe illness can occur. Recent travelers experiencing symptoms should consult healthcare providers.
In suspected or confirmed dengue areas, DOH personnel conduct inspections and activities to reduce mosquito populations which lowers transmission chances. Eliminating breeding sites around homes by removing standing water helps prevent mosquitoes from breeding.
