COVID-19: Millions in China face shutdowns as coronavirus cases surge and Shanghai access restricted

Although the country's infection numbers are relatively low, the authorities are enforcing a "zero tolerance" strategy to find and quarantine every infected person, and in some cities families have been told to stay at home. The authorities reported 1,938 new coronavirus cases on the Chinese mainland on Sunday, more than triple the previous day's total.Around three-quarters of those - 1,412 cases - were in Jilin province in the northeast, where entry to the industrial city of Changchun has been suspended and families told to stay at home. Stricter measures were introduced after officials decided an earlier response was inadequate. Advertisement Zhang Yan, deputy director of the provincial health commission, said: "The emergency response mechanism in some areas is not sound enough." In Shanghai, China's most populous city, the number of cases rose by 15 to 432.
