Held in Recife, Brazil, in 2015, EpiCrowd was a symposium on digital disease detection at mass gatherings. The event convened a group of technologists, epidemiologists, and ministry of health officials from 13 countries to explore how participatory surveillance tools can be used at mass gatherings.
EpiCrowd supported the ongoing development and improvement of the Guardians of Health application and preparation for the development of the Olympics tool interface. The event created opportunities and new platforms to fight epidemics during mass gatherings and fostered a community of epidemiology and information technology experts to collaborate and advance digital disease detection tools, as well as participatory surveillance systems in Brazil and globally.
