The Chinese city of Wuhan has begun drawing up plans to test its entire population of 11 million people for Covid-19, according to the state media report.
The plan appears to be in its early stages, with all districts in Wuhan having been told to submit details for how the testing could be done within 10 days.
This announcement comes after Wuhan, where the virus first emerged, recorded six new cases over the weekend.
Prior to this, there had been no new cases at all since 3 April.
Wuhan, which was in strict lockdown for 11 weeks, began re-opening on 8 April.
