3,798 dengue cases were reported in the U.S. in 2024, with 97.2% linked to travel outside the country, study finds.
In a recent report published by the Morbidity and Mortality Weekly Report, researchers documented that there were 3,798 dengue cases reported in the United States during the year 2024. Of these cases, an impressive 97.2% were associated with travel outside of the reporting jurisdiction. This highlights the significant role international travel plays in the spread of dengue fever within the U.S.
The study underscores the importance of travelers being aware of potential health risks before embarking on trips to areas where dengue is prevalent, such as parts of Asia and Latin America. Dengue is a viral disease transmitted by mosquitoes, particularly Aedes aegypti and Aedes albopictus, which can lead to severe complications including hemorrhagic fever in some cases.
Health officials recommend that individuals planning international travel take preventive measures such as using insect repellent, wearing long sleeves and pants, and staying in areas with air conditioning or using window screens. These precautions are crucial for reducing the risk of contracting dengue while traveling abroad.
While the majority of reported cases were linked to travel outside the U.S., it is essential that residents remain vigilant about symptoms such as fever, rash, headache, joint pain, nausea, vomiting, and muscle or bone pain. Early detection and treatment can help prevent more severe outcomes from dengue infection.
