It comes as the capital of China reported 27 new cases linked to a wholesale food market. The country was host to the origins of the pandemic that has spread across the globe, with original reports linking it to Wuhan.
Chinese authorities have mobilised nearly 100,000 community workers to the city.
Their orders were to test everyone who worked in or had visited the Xinfadi market near Beijing.
Xinfadi is the largest market in the capital, selling fruit and vegetables along with meat.
Beijing is home to around 21 million, and gets around 70 percent of it’s vegetables and 80 percent of it’s fruits from the market.

The market has been linked to more than 90 new cases of coronavirus over the weekend.
On Monday, 36 cases were linked to infection from Xinfadi.
According to state media reports Monday, Vice Premier Sun Chunlan said at a State Council briefing:”These clustered cases are highly correlated with the Xinfadi agricultural wholesale market, which has a highly mobile crowd and poses great outbreak risks.
“We have to take firm action and resolute measures to effectively stop the epidemic from spreading.”
Parts of Beijing have been placed into lockdown measures as well in an attempt to tackle the resurgence of the virus.
WHO director-general Tedros Adhanom Ghebreyesus told a virtual press conference: “More than 100 cases have now been confirmed.”
He also added that the origins of the resurgent Xinfadi cluster were unclear.
WHO emergencies director Mike Ryan added: “A cluster like this is a concern and it needs to be investigated and controlled – and that is exactly what the Chinese authorities are doing.”
It is a huge blow for the controversial nation, who began lifting restrictions in April: April 7 saw Wuhan’s lockdown restrictions lifted.
The Beijing Daily reported on Monday that key party officials were removed from their posts because of the new outbreak.
These included the party secretary in the area that incorporates Xinfadi and the general manager of the market, while the deputy head of the district was fired for “failing” in his duty to prevent and control the coronavirus.
