"Dengue Public Health Emergency Declared in Rio de Janeiro Before Carnival"

Rio de Janeiro has declared a public health emergency due to a surge in dengue fever cases just before the Carnival celebrations. The city has implemented special measures, including the opening of care centers and the use of insecticide "smoke cars" to contain the outbreak. The outbreak, which has seen over 10,000 cases since the beginning of 2024, has prompted the state to take action, with the Brazilian air force setting up a field hospital in the Federal District. Dengue, a viral infection transmitted by mosquitoes, is more common in tropical climates and has prompted several states in Brazil to declare public health emergencies. Climate change is associated with a higher risk of dengue, and the mayor has urged residents to eliminate mosquito breeding grounds.
