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 3 April.
Wuhan, which was in strict lockdown for 11 weeks, began re-opening on 8 April.
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.
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.
However several senior health officials quoted by the Global Times newspaper indicated that testing the entire city would be unfeasible and costly.
Peng Zhiyong, director of the intensive care unit of the Zhongnan Hospital of Wuhan University, instead that testing was instead likely to be targeted at medical workers, vulnerable people and those who’d had close contacts with a case.
Another Wuhan University director suggested that a large percentage of Wuhan’s population – around 3-5 million – had already been tested, and Wuhan was “capable” of testing the remaining 6-8 million in a 10-days period.
