An outbreak of SARS-CoV-2 among U-20 ice hockey teams in Finland was reported based on public statements by the local health authorities and the teams involved. One player who had asymptomatic COVID-19 infected 22 of 28 teammates. The team had returned from an away trip the day before the first players had symptoms. COVID-19 was detected in both teams a few days later. During two weeks of quarantine, a total of 24 players from the two opposing teams tested positive. Some of these players infected additional players on other teams. In total, 49 infections were detected in five ice hockey teams, and six teams were in quarantine for two weeks.
