This is a have a look at the theories the group explored throughout their go to:

Bats

The Wuhan mission didn’t change a significant concept concerning the origin of the virus.

Former US President Donald Trump and officers in his administration have been amongst those that raised the chance – prompting indignant denials from China. And most consultants have lengthy been skeptical.

In making their resolution, the group stated such leaks have been extraordinarily uncommon and there was no proof the virus existed on this lab or any lab on this planet when the pandemic started.

Marion Koopmans, a member of the WHO group, famous that this nonetheless doesn’t reply the query of the origin of the virus. “It is not the chilly chain per se, it might’t be,” she instructed the airport. “The virus has to return from someplace.”

THE DATA
