A dozen province-level regions contained their flare-ups within weeks in the current outbreak, thanks to quick implementation of a complex set of curbs, including rigorous contact tracing, multiple rounds of testing of people in at-risk areas, the closure of entertainment and cultural venues, and restrictions on tourism and public transport.
However, Dalian remains locked in a struggle with the virus, National Health Commission official Wu Liangyou said.
Since Dalian’s first local symptomatic patients from the latest outbreak were reported on November 4, the city of 7.5 million people has detected an average of about 24 new local cases a day, more than any other Chinese city, according to Reuters calculations.
