Petrolina | World Mosquito Program Skip to main content

View the latest updates from the World Mosquito Program in Petrolina.

The World Mosquito Program works in Petrolina to protect communities from mosquito-borne diseases like dengue, Zika, chikungunya and yellow fever.

The WMP has been actively working in Brazil since 2012, when it was called Eliminate Dengue: Challenge Brazil. In July 2021, the release of Aedes Aaegypti mosquitoes with Wolbachia in Petrolina began in the communities of Antônio Cassimiro, Cosme e Damião, Dom Avelar, Jardim São Paulo, João de Deus, São Gonçalo, Novo Tempo and Pedra Linda and their surroundings. These pilot projects have been monitored since September 2021 and their results are recorded for analysis of the effectiveness in establishing mosquito populations with Wolbachia in the region.
