Shanghai hunts COVID cases in lockdown’s sixth week

STORY: The Chinese commercial hub of 25 million people has in recent days been tightening its lockdown for a final push to eradicate the virus by the end of the month, having made some significant progress, according to data this week.

Shanghai's mass testing detected just two new cases outside areas facing the strictest curbs on May 11, officials said on Thursday, but that was two more than none the previous day. Significantly, the cases were found in two of the city's 16 districts, Xuhui and Fengxian, that authorities said this week were among eight that had achieved "zero COVID" status, having had no community cases for three consecutive days.

The latest cases show the difficulty in finishing off the highly transmissible Omicron variant despite ruthless enforcement of some of China's harshest restrictions since the virus emerged in the city of Wuhan in late 2019.
