So where did the SARS-CoV-2 virus come from? Was it a natural process or a laboratory-made virus?
Peter Embarek, leader of the World Health Organization (WHO) team of investigators, now says that the first person infected with the SARS-CoV-2 virus may have been an employee at the virology laboratory in Wuhan.
COVID-19: Employee may have been infected with SARS-CoV-2 while taking bat samples
Peter Embarek's statements come at a time when the exchange of accusations about the origin of the virus intensifies, with China insisting, this Friday, that the investigation should be extended to other nations.
Speaking to the Danish television channel TV2 Peter Embarek said that regarding SARS-CoV-2...
One of the likely hypotheses for the origin of the virus is that an employee at the Wuhan laboratory was infected while taking samples of bats in the field.
It was here that the SARS-CoV-2 virus passed directly from a bat to a human. In this case, transmission would have started in a laboratory technician and not an ordinary citizen when dealing with bats.
However, Embarek said the WHO did not find direct evidence that the COVID-19 outbreak was linked to any ongoing investigation in that Chinese laboratory.
Recall that the report from the first WHO mission to Wuhan, published in April, pointed to four possible sources of the SARS-CoV-2 virus, with the exception that a laboratory accident was the least likely theory. However, the WHO itself began in recent weeks to give greater prominence to that possibility.
Tedros Adhanom Ghebreyesus, director general of WHO, has called on China "to be transparent and open" and provide "raw data about the first days of the pandemic". Liang Wannian, head of the team of Chinese experts investigating the origin of the new coronavirus, argues that "the next phase of investigations into SARS-CoV-2 should be carried out in other countries."
