The Brazilian Ministry of Health is launching a wonderfully innovative and socially good smartphone app called Guardioes de Saude (Guardians of Health), that is designed to track the Zika virus as well as a range of other known epidemics in the country during the Olympic and Paralympic games.
These huge sports events will result in massive numbers of athletes and tourists flooding the country of Brazil, something which could potentially result in an increased likelihood of the spread of diseases transmitted by mosquitoes. This is where the Guardians of Health app comes in. The app doesn't merely track the Zika virus but it also shares data with concerned authorities in order to inform measures.
Ultimately, this app is a great example of smartphone technology being leveraged for public health gains.
