Wuhan, known as the epicentre of the COVID-19 outbreak, has just started reopening businesses and schools after being in lockdown since January.

Elderly man became first patient
The city, which has a population of 11 million, has reported six new infections since lockdown measures were lifted on 8 April.Mothership SG, quoting Chinese website The Paper, reported that the six cases came from a small residential complex in Wuhan.
According to the report, the first patient of the new cluster was an 89-year-old man.
The man reportedly fell ill with COVID-19 symptoms on 17 March, but he recovered ten days later. However, he started feeling ill again on 15 April.

Mass testing to be carried out
Due to that, authorities announced on the same day that mass testing of the entire Wuhan population would be carried out and would be completed within 10 days.Called the "10-day battle", districts were tasked to come up with their own plans to execute the testings.
To complete the task within 10 days, more than one million tests would have to be conducted each day.
