Koronavirus-showcase shows you the number of infections in Finland at the current moment and also e.g. the number of people who have recovered from the virus. You can also look a timeline of Coronavirus in Finland and the number of infections in different hospital districts.
The showcase is only available in Finnish. It uses open data from Helsingin Sanomat which is updated whenever there is a new infection.
Note that the map does not give an accurate view of the Coronavirus situation in Finland because since 14.3. health authorities are no longer testing all patients presenting with symptoms in Finland. Thus the actual number of infections is bigger.
