The Hawai‘i Department of Health has confirmed a new travel-related dengue virus case on Oʻahu, bringing the total number of cases to seven in the state this year (one on Maui, six on Oʻahu). The affected individual was exposed to the virus while traveling in a region with common dengue transmission.
DOH teams are inspecting and implementing mosquito control measures in the affected area. The public is advised to follow best practices to prevent local transmission:
– Use EPA-registered insect repellent
– Wear long-sleeved shirts and pants outdoors
– Sleep in air-conditioned rooms with screens or under-insecticide-treated bed nets
Dengue virus is transmitted through an infected person to a mosquito, then to another person. The disease is not endemic in Hawai‘i but is present in other tropical regions, such as the Pacific Islands and Central America.
Travelers to or from areas with dengue risk should take precautions:
– Review country-specific travel information
– Use insect repellent and protective clothing
– Sleep indoors
Symptoms of dengue can range from mild to severe and include fever, nausea, vomiting, rash, and body aches. If symptoms develop, travelers should seek medical evaluation.
DOH personnel are conducting inspections and mosquito-reduction activities in areas with suspected cases. Reducing mosquito populations lowers the risk of transmission. Eliminating standing water around homes can also prevent breeding.
