HONG KONG—Hong Kong reported 1,347 new daily COVID-19 infections on Sunday, down from the previous day’s record, but the spread, with 2,000 more suspected cases, threatens the city’s overstretched healthcare system, authorities said.
The surge in COVID-19 cases, the biggest test yet for Hong Kong’s “zero-COVID” strategy, comes a day after the government said China would help the city with testing, treatment, and quarantine capacity.
