BEIJING (AFP): A Chinese city of nearly six million people will introduce a wave of coronavirus testing to stamp out a small cluster of cases, authorities said Friday (July 24), with state media reporting communities will be locked down.

Since the virus first surfaced in the central city of Wuhan late last year, the country's official number of infections has been restricted to a trickle, mainly among arrivals from abroad. All mass lockdowns have been lifted.
