China is requiring all international Olympic attendees — including coaches and journalists — to log into a health monitoring system at least 14 days before their departure. They can use the app to do so, or can log in through a web browser on a PC. The app allows users to submit required health information on a daily basis and is part of China's aggressive effort to manage the coronavirus pandemic while hosting the games, which begin Feb. 4. The multipurpose app also includes chat features, file transfers, weather updates, tourism recommendations and GPS navigation.
