Macau kicked off a new round of COVID-19 testing for its more than 600,000 residents on Monday, as officials in the world's biggest gambling hub raced to limit spiralling infections in the city's worst outbreak since the pandemic began.
All residents face three rounds of tests this week, in addition to rapid antigen tests, as Monday's 68 new infections took the tally in the former Portuguese colony to 852 since the middle of June. About 12,000 people are in quarantine.
