The Chinese city of Wuhan is drawing up plans to test its entire population of 11 million people for Covid-19, state media report.
The plan appears to be in its early stages, with all districts in Wuhan told to submit details as to how testing could be done within 10 days.
It comes after Wuhan, where the virus first emerged, recorded six new cases over the weekend.
Prior to this, it had seen no new cases at all since April 3, 2020.
Wuhan, which was in strict lockdown for 11 weeks, began re-opening on April 8, 2020.
For a while, it seemed like life was getting back to normal as schools re-opened, businesses slowly emerged and public transport resumed operations. But the emergence of a cluster of cases all from the same residential compound has now threatened the move back to normalcy.
According to report by The Paper, quoting a widely circulated internal document, every district in the city has been told to draw up a 10-day testing plan by noon on Tuesday, May 12, 2020.
Each district is responsible for coming up with its own plan based on the size of their population and whether or not there is currently an active outbreak in the district.
The document, which refers to the test plan as the “10-day battle”, also says that older people and densely populated communities should be prioritised when it comes to testing.
China reported just one new case on Monday, May 11, 2020, bringing the total number of cases to 82,919, with the death toll at 4,633.
Hundreds of asymptomatic cases are being monitored by Wuhan health authorities.
