The first clusters of Covid-19 were detected in Wuhan in late 2019, prompting the government to put the city of 11 million under a strict 76-day lockdown.
One of the World Health Organisation investigators looking for clues into the origin of the coronavirus in the central Chinese city of Wuhan said that the Chinese side has provided a high level of cooperation.
The Wuhan Institute of Virology has collected extensive virus samples, leading to unproven allegations that it may have caused the original outbreak by leaking the virus into the surrounding community. China has strongly denied that possibility and has promoted unproven theories that the virus may have originated elsewhere.
Along with the institute, the WHO team that includes experts from 10 nations has visited hospitals, research institutes and a traditional market tied to the original outbreak.
Ever since the first clusters of Covid-19 were detected in Wuhan in late 2019, China has reported more than 89,000 cases and 4,600 deaths, with new cases largely concentrated in its northeast and local lockdowns and travel restrictions being imposed to contain the outbreaks. It is time to find out the root cause.
