Since then, the cluster has unfold to at the very least 26 cities throughout China, together with a vacationer scorching spot within the southern province of Hunan and the capital Beijing.

Chinese language authorities responded swiftly with mass testing, focused lockdowns, in depth contact tracing and quarantine of shut contacts — a tried and examined components that has helped it shortly tame native flare-ups since March 2020.

Huang Yanzhong, senior fellow for World Well being on the Council on International Relations, stated Chinese language authorities are responding to the specter of the Delta variant with the identical playbook utilized in earlier outbreaks, however in an much more stringent method — a number of cities have been positioned below efficient lockdowns.

“It reveals the issue of diminishing returns of the prevailing ‘zero-tolerance’ strategy,” he stated.

Elsewhere on the planet, international locations with comparatively excessive vaccination charges are more and more selecting to tolerate a level of transmission, so long as it does not translate right into a surge in hospitalizations and deaths.
