After two years of research, this is the first time that a Latin American country has tested a method already functioning in Vietnam, Indonesia and Australia, where the first eggs of the dengue-carrying Aedes aegypti mosquitos inoculated with Wolbachia were imported to Brazil.
The researchers hope to obtain results next year when the majority of the mosquitoes in Tubiacanga should already be immunized and harmless to people.
Brazil has been the country most affected by dengue since 2000, with seven million cases reported.
