Fighting dengue mosquitoes together: In Brazil, government and citizens are fighting together against dengue fever with the help of the app Sem Dengue (“dengue-free”). For decades, there have been continual outbreaks of the virus, especially in the most populous cities, São Paulo and Rio de Janeiro. With this app, the citizens send pictures of stagnant water or open cesspools – where Dengue mosquitoes like to breed – to the city administration, which functions as an early warning system. Currently, Sem Dengue is maintained by 100,000 registered users in 30 cities around the country.
