Brazilian municipalities intensify combat against Aedes aegypti

Municipalities in Brazil are intensifying efforts to combat Aedes aegypti, the mosquito responsible for transmitting dengue, zika, and chikungunya.

In Tangará da Serra, health authorities report a significant reduction in high-infestation areas, known as “red areas.” The number of these zones has decreased from 88 at the beginning of the year to 24. Environmental surveillance teams are conducting house inspections, strategic spraying, and educational lectures to maintain this progress as the city prepares for upcoming mosquito index surveys.

In Dourados, the municipal government has launched a task force focused on urban cleaning and the elimination of mosquito breeding sites. Concentrated in the Jóquei Clube and Vila São Braz neighborhoods, the initiative includes weeding, mowing, and the collection of waste materials. These actions follow a public health emergency decree issued earlier this year in response to a chikungunya epidemic that resulted in 19 deaths in the region. The task force also includes environmental education programs in local schools.
