China has ordered areas with populations of more than 5 million to be fully tested for Covid-19 within three days, while those with less than 5 million residents have two days to do the same.
The National Health Commission notice on Tuesday came as the country recorded the highest daily totals of local and symptomatic cases during its latest coronavirus outbreak.
“Once the decision is made to carry out mass testing, implementation plans must be put in place as soon as possible,” the NHC notice said.
