Can China's extreme anti-coronavirus measures ensure a COVID-free Beijing Winter Olympics?

All the residents of Beijing's Fengtai district lined up in the cold for mandatory COVID-19 tests this weekend. The mass-testing was imposed on the area after just 31 coronavirus cases were reported locally — but also as the opening ceremony of the Beijing Winter Olympics loomed just 10 days away.

As CBS News Asia correspondent Elizabeth Palmer reports, elsewhere in China, strict lockdowns that had affected millions of people have been lifted as the number of cases declined.

But in Beijing, a city official told reporters that citizens "must go all-out… to break the chain of infection in the current outbreak as fast as possible."
