The Olympic 'bubble' was created as a preventive measure against the spreading of Covid-19, where reporters, athletes, and other people taking part in the upcoming Winter Olympics have to live in a closed-loop environment for the whole time without being able to leave it up until their departure from China. From more than 3,000 people arriving for the Olympics since 04 January 2022, over a hundred in total were tested positive for the coronavirus COVID-19 disease. The Beijing 2022 Winter Olympics is scheduled to start on 04 February 2022. EPA/ROMAN PILIPEY
