Shanghai Extends Lockdown as City Tests Its 25 Million Residents for Covid

Shanghai extended lockdown measures as it concluded a day of testing of all 25 million of its residents for Covid-19 Monday, aided by thousands of medical workers who arrived over the weekend from across the country. Late Monday, which was meant to be the final day of lockdown, the municipal government said the lockdown would continue until after the authorities finished evaluating the situation, including reviewing the results of the mass-testing effort. It said by evening, it was nearly done with the citywide testing. Shanghai had planned a two-phase lockdown, in which half the city’s residents would be confined to their homes at a time, depending on which side of the Huangpu River they lived. The first four-day lockdown of residents to the east and south of the river was to have ended Friday. The second stage was due to end at 3 a.m. Tuesday.
