China’s Covid Zero strategy is being tested anew after a jump in infections across Shanghai raised the specter of another lockdown, while a highly infectious subvariant started spreading in the country for the first time.
Shanghai reported 24 infections for Tuesday, the most in three weeks, with health officials announcing separately on Wednesday that two additional cases were found outside quarantine.
