In less than two weeks a team of 15 designers and software developers produced SymptoTrack, a platform meant to track as many cases of COVID-19 infections as possible. The more people, who currently are not tested, register their symptoms at SymptoTrack.org, the better we will be able to map the spread of the coronavirus. Initiated by social entrepreneur Adrian Dongus the open-source platform SymptoTrack was developed by volunteers from three Dutch internet design and development agencies Greenberry (design), Hike (development) and Forest (development and hosting). They worked day and night to develop the site as quickly as possible. The idea behind the platform is that under the current circumstances, with limited testing capacity throughout the world, individuals with mild COVID-19 symptoms are told to stay at home and their cases are not calculated in the statistics. This means we don’t have an accurate view on the scale and speed at which the virus spreads.
