CDC warns travelers of dengue fever risks in spring

The Centers for Disease Control and Prevention (CDC) has issued a warning to travelers about dengue fever, a disease spread by mosquitoes. The warning comes as spring break travel begins, with popular destinations seeing high levels of transmission. Nearly 1,000 cases have been reported so far this year in the U.S., and much higher numbers are seen in places like Mexico and Puerto Rico. Dengue fever can cause symptoms such as fever, headache, and rash. In severe cases, it may lead to heavy bleeding, including nosebleeds. These serious cases can be life-threatening without proper treatment. The CDC advises travelers to take precautions, such as wearing long sleeves and using insect repellent, to prevent mosquito bites. The CDC's warning highlights an ongoing increase in dengue cases linked to climate factors like the El Niño phenomenon, which affects rainfall and mosquito breeding. Officials also noted that only one in four dengue patients shows symptoms, making it important for those returning from travels to watch for signs of illness. As travel continues, the CDC expects that the number of dengue cases could rise further. Travelers, especially those going to areas with high transmission rates, should stay alert and take protective measures to keep themselves safe.
