Chief Executive Carrie Lam Cheng Yuet-ngor said today that Hong Kong has reported no Covid cases in the city for 56 days in a row, with Hong Kong having achieved “zero local infections”.

Speaking at a press conference over the city’s Covid rules, Lam said changes will be made to the current risk-based boarding and compulsory quarantine requirements for arrivals.

Specific places will be categorized into three groups - high-risk, medium-risk, and low-risk.

According to the new measure, only vaccinated Hong Kong residents will be able to return to the city from high-risk areas. As for medium-risk areas, only Hong Kong residents and vaccinated non-residents can board flights to Hong Kong. All returnees will still have to present a negative Covid test result before boarding the relevant flights to the city.

The new measure would also see returnees from high-risk, medium-risk, and low-risk areas undergo compulsory quarantine for 21, 14, and 7 days respectively.

Meanwhile, Lam said all workers that would come into contact with these arrivals will be required to get vaccinated, including airport workers, quarantine hotel staff, and transportation workers.
