OREANDA-NEWS So he commented on the report of the Republicans from the US, according to which the coronavirus originated in a laboratory in Wuhan, China, where it was "leaked".

“It is very difficult to prove that it was the leak that caused the pandemic, it goes beyond a biological problem. This can be proved by some indirect evidence, but hardly biological”, - Lukashev clarified in an interview with RIA “Novosti”. 

At the same time, a scenario with a possible virus leak does not necessarily mean the artificial creation of a virus, the expert emphasized. So, scientists could investigate a natural virus by accidentally contracting it.

The corresponding report on the coronavirus leak from the Wuhan laboratory was published earlier in the day. The document states that a laboratory in Wuhan conducted tests of "gain-of-function mutations" while the work was carried out "in an unsafe environment". It is also believed that the first cases of coronavirus occurred in August or September 2019.
