HONG KONG — China on Sunday reported two additional deaths from COVID-19 as some cities move cautiously to ease anti-pandemic restrictions following increasingly vocal public frustrations. The National Health Commission said one death was reported each in the provinces of Shandong and Sichuan. No information was given about the ages of the victims or whether they had been fully vaccinated. China, where the virus first was detected in late 2019 in the central city of Wuhan, is the last major country trying to stop transmission completely through quarantines, lockdowns and mass testing.
