Qatar has reported that five corona virus cases have been detected in workers at three World Cup stadiums, the first confirmed instances among those involved in the 2022 tournament projects.

The Gulf nation has reported a total of seven deaths, 3,711 COVID-19 infections and 406 recoveries since March 6 but had not previously disclosed any positive tests from workers at World Cup sites.

Qatar is building seven new stadiums for the tournament, one of which has officially opened, while one existing venue was refurbished ahead of 2022.
