BEIJING, July 11 (Reuters): Multiple Chinese cities are adopting fresh Covid-19 curbs, from business halts to lockdowns, to rein in new infections, with the commercial hub of Shanghai bracing for another mass testing effort after finding a highly-transmissible Omicron subvariant.

The tough curbs by local governments follow China's "dynamic zero-COVID" policy of promptly stamping out all outbreaks at a time when much of the world co-exists with the virus.
