Brazil Issues Warning About Widespread Cases of Dengue Fever


Health officials in Brazil issued a warning about widespread cases of dengue fever just as hundreds of thousands of people gathered in Rio de Janeiro and other cities for the annual Carnival celebration, which reaches its climax today.

Carnival will soon be over, but dengue will remain a hazard for travelers to Brazil and other parts of the Americas, experts say.

Rio officials declared a health emergency last week about dengue, a tropical disease that is carried by mosquitoes and can cause symptoms ranging from fever to death. In 2024, Brazil has already reported at least 10,000 cases of dengue fever.
