“According to our experts, this is evidenced by the variability of genovariants, which is not typical for most coronaviruses, causing different peaks in their incidence, significant differences in mortality and contagiousness,” RIA Novosti quoted Kirillov as saying.

The military commander noted that Washington's interest in studying "narrow-targeted" biological agents allows us to take a fresh look at the causes of the coronavirus pandemic, as well as "the role of US military biologists in the emergence and spread of the COVID-19 pathogen."

In July, State Duma speaker Vyacheslav Volodin said that US military biological development should be stopped and declassified.

Doctor of Biological Sciences, professor at the School of Systems Biology at George Mason University, virologist Ancha Baranova said that the virus can be developed in vitro to obtain its various mutations.
