Blinken noted that according to a number of studies, the coronavirus could have occurred as a result of a laboratory leak in Wuhan.

In addition, according to another version, the source of the virus could be in the animal market in Wuhan.

At the same time, he added, no one can establish the final cause.

“The likelihood that COVID-19 was created in the laboratory is obvious and very real, but it is not final,” RIA Novosti quoted Blinken as saying.

In mid-February, the US House of Representatives launched an investigation into the origins of COVID-19, requesting information from officials in the administration of US President Joe Biden.
