Last week, US President Joe Biden ordered his intelligence agencies to investigate the theory that COVID-19 leaked from a laboratory in the Chinese city of Wuhan. The idea was previously dismissed as a conspiracy theory.
COVID-19 was first detected in 2019 in Wuhan in the central Hubei province.
Since then over 3.5 million people have died due to the virus, according to data from Johns Hopkins University.
Mr Biden called for intelligence officials to “redouble” efforts to investigate the origins of COVID-19, including the lab leak theory.
His announcement came after a US intelligence report found that several researchers at China’s Wuhan Institute of Virology fell ill in November 2019.

“That means starting an investigation, along with partners around the world and in the WHO.”
According to the publication, British agents now believe it is “feasible” that the pandemic began with a lab leak in China.
China has denounced America’s efforts to further investigate whether the virus came from a Chinese lab.
China’s Foreign Minister, Zhao Lijian, said: “The US doesn’t care about facts or truth at all, neither is it interested in a serious scientific study on the origins.
“Its only aim is to use the pandemic for stigmatization and political manipulation to shift the blame.”
The World Health Organization said it is “extremely unlikely” that COVID-19 spread from a lab leak after a visit to Wuhan earlier this year to investigate the origins of the pandemic.
