HONOLULU — The Hawaii Department of Health is reporting its 12th travel-related dengue fever case this year, a growing concern for tropical travelers and public health officials.
“Dengue is not endemic in Hawaii, but cases—they’re currently limited to returning travelers—are surging.” Hawaii DOH notes, as shared by Fox News Digital.
Rising Numbers and Locations
Of the 12 reported infections, 11 have been confirmed on O‘ahu, and one on Maui. Each case was linked to travel in regions where dengue is widespread, underscoring the virus’s status as a travel-associated risk rather than local transmission.
Dengue on the Rise Globally
Globally, dengue cases are climbing at alarming rates: over 3.2 million suspected cases and more than 4,100 severe cases were recorded in Latin America and the Caribbean by mid-2025. In 2024 alone, more than 13 million suspected infections and over 8,000 deaths were reported.
Health Advisories and Precautionary Measures
The Hawaii DOH is urging returning travelers to take preventive steps—using EPA-registered insect repellent, wearing long clothing outdoors, and eliminating standing water to curb mosquito breeding. If symptoms arise within two weeks, medical evaluation is advised.
The Centers for Disease Control and Prevention (CDC) affirms that while dengue is not endemic in Hawaii, sporadic travel-linked infections can spark local outbreaks—especially given Hawaii’s populated mosquito species like Aedes aegypti.
Public Health Concerns
Though most dengue cases resolve within days to a week, severe manifestations—including hemorrhagic fever and shock—are life-threatening. With tourism rebounding, officials worry increased travel could bring more imported cases.
Dr. Mark Fischer of International SOS notes the importance of preventing mosquito bites and seeking timely treatment. Hawaii\’s Vector Control Branch is actively inspecting affected areas and deploying vector reduction measures.
Travel and Lifestyle Implications
The surge coincides with peak tourist season, prompting heightened public health messaging. While the state remains dengue-free domestically, preventive vigilance is now critical for both travelers and residents.
