U.S. health officials issued a warning to doctors about the rise of dengue cases globally. They emphasized the importance of being vigilant for this mosquito-borne virus, especially in travelers returning from abroad. While there is no current outbreak in the U.S., the number of cases has tripled compared to last year. Dengue is more prevalent in tropical regions, affecting nearly half of the world’s population. Recently, the World Health Organization declared a global emergency, and Puerto Rico declared an epidemic. Local mosquitoes in certain U.S. regions pose a risk, prompting officials to urge doctors to be aware of symptoms and travel history. Dengue, also known as “break-bone fever,” is transmitted through mosquito bites. Climate change has contributed to the spread of the virus. Travelers are advised to take precautions, such as using insect repellents and avoiding areas with standing water. Severe cases of dengue can be life-threatening, so prompt medical attention is crucial.
