Rio de Janeiro Declares Dengue Health Emergency Ahead of Carnival

The city takes preemptive measures to contain the outbreak, including opening care centers and using insecticide diffusion.

Rio de Janeiro has declared a public health emergency due to a significant outbreak of dengue fever.
The outbreak comes just days before the annual Carnival celebrations, expected to draw large crowds.
Authorities have initiated several measures, such as opening 10 care centers and deploying 'smoke cars' to diffuse insecticides in high-incidence areas.
Since the beginning of 2024, Rio has registered over 10,000 dengue cases, nearly half of 2023's total.
The national issue has prompted at least four other Brazilian states to declare public health emergencies.
