BEIJING: Authorities in China’s Wuhan said Tuesday they would test the city’s entire population for COVID-19, as the virus returned to the place where it first emerged and the highly contagious Delta variant drove tightening lockdowns worldwide.
A resurgent virus has returned with a vengeance, buoyed by stalling vaccination rates and deadly new mutations even in places which had long touted their successes in overcoming the worst of the pandemic.
China brought domestic cases down to virtually zero after the coronavirus first emerged in Wuhan, allowing the economy to rebound and life to return largely to normal.
But a fresh outbreak has thrown that record into jeopardy, as the fast-spreading Delta variant reaches dozens of cities after infections among airport cleaners in Nanjing sparked a chain of cases that have been reported across the country.
In Wuhan — where the virus first emerged in December 2019 and which faced a grueling lockdown in the early months of the pandemic — authorities said they were launching a mass-testing program for all 11 million residents.
And across China, authorities have confined the residents of entire cities to their homes, cut domestic transport links and rolled out mass testing in recent days as the country battles its largest coronavirus outbreak in months.
Millions are also still under movement restrictions in Australia, where troops Monday hit the streets of the country’s largest city of Sydney and surrounding areas, which are entering the sixth week of a lockdown set to run until the end of August.
Authorities have been struggling to stop the spread of the highly infectious Delta variant in the city — and to ensure that residents follow containment rules — with more than 3,600 cases recorded since mid-June.
With about 15 percent of Australia’s 25 million people fully vaccinated, authorities are still relying on lockdowns to slow the spread of the virus.
