The fourth phase of the Wolbachia project has already released 32 million wolbits in the 33 districts of the capital, which are dengue mosquitoes carrying the Wolbachia bacterium. The aim is to reduce the incidence of Dengue, Zika and Chikungunya.

Wolbachian method – Wolbachia is an intracellular bacterium that occurs in 60% of natural insects but was not present in Aedes aegypt. When present in a mosquito, it prevents the development of Dengue, Zika, Chikungunya and yellow fever viruses. There is no genetic modification in mosquitoes or bacteria.

The Wolbachia method consists of releasing Aedes aegypt with Wolbachia to reproduce with the native Aedes aegypt and to create a new population of these mosquitoes, all with this bacterium. Over time, the percentage of mosquitoes carrying Wolbachia will increase until it remains high with no additional emissions.

The Wolbachia method, developed by the World Mosquito Program in Australia, is an international non-profit initiative that seeks to combat mosquito-borne diseases. Currently, the method, which works in 12 countries and more than 20 cities, has shown promising results in different locations.

In Brazil, the method is being implemented by the Oswaldo Cruz Foundation (Fiocruz) with funding from the Ministry of Health in collaboration with local governments. The WMP method is currently being implemented in Campo Grande (MS), Petrolina (PE) and Belo Horizonte (MG) with funding from the Ministry of Health and in collaboration with local government and several other regional partners.
