Dengue fever, common in the Middle East, Asia, Pacific Islands, the Americas, and other regions, is a virus transmitted through bites from infected mosquitoes. The peak season for dengue often coincides with spring and summer travel, increasing the risk of both travel-associated and locally acquired cases in the United States, according to CDC reports. With over 13 million cases reported globally in 2024, the CDC has issued a health alert, advising precautions such as using insect repellent and wearing protective clothing.
