"Dengue Emergency Looms Over Brazil's Carnival Preparations"

Rio de Janeiro's mayor has declared a state of public health emergency due to a dengue epidemic as the city and the rest of Brazil prepare for carnival celebrations. The surge in dengue cases has led to a record number of hospitalizations, prompting the city to plan the creation of ten centers to combat the disease and the vaccination of 354,000 children as soon as vaccines are released. Dengue, a mosquito-borne virus, is spread by the Aedes aegypti mosquito and can cause symptoms such as fever, nausea, and joint pain, with no specific medicine for treatment.
