Hong Kong’s health officials warned that the city is facing a "crisis” as a record 2,000 preliminary positive cases threatened to overwhelm hospitals and upend its "COVID zero" strategy.

Authorities on Sunday reported 1,347 infections and said more than 3,400 confirmed patients were receiving treatment. Cases have exceeded capacity at Hong Kong’s hospitals, health officials said, adding they will now shift to prioritizing care for the elderly and children who test positive.

With daily COVID-19 infections seeing a breakneck surge from just 14 about three weeks ago, officials sought Beijing’s support over the weekend on several fronts including help with analyzing virus strains, building isolation facilities and the supply of test kits.
