As summer begins, health officials are preparing for rising dengue cases in the United States, which have increased significantly from previous years. Recent data indicates 3,700 infections last year, with only 105 cases acquired locally. Experts warn that climate change and lack of effective vaccination could lead to dengue becoming endemic to North America. The disease, commonly spread by Aedes mosquitoes, has surged in warmer regions globally. While most infections are mild, severe symptoms can occur, making dengue a concerning public health issue.
Dengue infections in the contiguous United States surged to 3,700 in 2023 from approximately 2,050 in 2022, with cases primarily acquired abroad except for 105 local instances.
Infectious disease specialist Michael Ben-Aderet emphasized that dengue is likely to become endemic in the U.S., stating, "These mosquitoes aren't going anywhere."
Dengue, which spreads through Aedes mosquitoes, has shown alarming increases in warmer regions globally, with public health officials predicting its prevalence to rise in the U.S.
Most dengue patients experience mild symptoms, but severe cases can include bleeding, intense abdominal pain, vomiting, and can lead to fatalities.
