Rio de Janeiro has declared a public health emergency because of an outbreak of mosquito-borne dengue fever, the city said in its official gazette on Monday, just days before Carnival celebrations kick off across Brazil, Paralel.Az reports citing The Washington Post.

But the outbreak wasn’t expected to disrupt Carnival, which officially starts on Friday evening and runs until Feb. 14.

Rio city hall announced the opening of 10 care centers, the creation of an emergency operations center and the allocation of hospital beds for dengue patients. Authorities will also use “smoke cars” in regions with the highest incidence of cases, diffusing an insecticide in the air.

Since the beginning of 2024, the municipality has registered more than 10,000 dengue cases. That is just under half of the total cases — 23,000 — recorded throughout all of 2023.
