Hawaii on Alert: First Travel-Related Dengue Case of 2026 Signals Rising Global Risk
The Hawaii Department of Health (DOH) has confirmed the first travel-related case of dengue fever in the state this year, detected on Maui. This case serves as a crucial reminder of the ongoing global threat of dengue and the importance of preventative measures for both residents and visitors.
Dengue Fever: A Growing Global Concern
Dengue virus is spread through the bite of infected mosquitoes. While Hawaii’s mosquito population can carry the virus, the disease isn’t currently established within the state. cases are limited to those who contracted it while traveling. However, several countries are currently reporting higher-than-usual dengue case numbers, including Afghanistan, Bangladesh, Cook Islands, Samoa, Vietnam, Colombia, Cuba, Nicaragua, Mali, Mauritania and Sudan. This increase underscores a broader global trend.
Where is Dengue a Risk?
Dengue is a year-round risk in tropical and subtropical regions. High-risk areas include Central and South America (like Brazil and Mexico), Asia (including the Philippines), the Middle East, Africa, and several Pacific Islands, such as American Samoa, the Federated States of Micronesia, the Republic of the Marshall Islands, and the Republic of Palau. Popular tourist destinations in the Caribbean, including Puerto Rico, are also affected.
Protecting Yourself: Travel Precautions
The Centers for Disease Control and Prevention (CDC) recommends standard precautions for travelers visiting dengue-risk areas. These include consistently using EPA-registered insect repellent, wearing long-sleeved shirts and long pants when outdoors, and ensuring accommodations are either air-conditioned or equipped with window screens or insecticide-treated bed nets.
What to Do After Travel
Travelers returning from dengue-endemic areas should continue to protect themselves from mosquito bites for three weeks. If you develop symptoms – which can range from mild to severe and include fever, nausea, vomiting, rash, and body aches – within two weeks of returning, seek medical evaluation. Symptoms typically last two to seven days, and while severe illness is possible, most people recover within a week.
Hawaii’s Response and Prevention Efforts
The DOH has deployed teams to the affected area on Maui to conduct inspections and implement mosquito control measures. Reducing mosquito populations is key to lowering the risk of local transmission. Residents can help by eliminating standing water around their homes and workplaces – common breeding sites include buckets, planters, and even discarded cups.
The Role of Vector Control
DOH personnel from the Vector Control Branch (VCB) actively operate to reduce mosquito populations in areas with suspected or confirmed dengue cases. Even in areas without reported cases, eliminating breeding sites around your property is a proactive step.
