Research has not yet determined which host was the host that harbored the virus and then passed it on to humans.
A team from the World Health Organization (WHO) in Wuhan confirmed this Tuesday, February 9, 2021, that the coronavirus is of zoonotic origin, but the animal that served as a host and carried the virus has not yet been identified. the humans.
The WHO analyzed in Wuhan, the place where Covid-19 was first detected, 4 hypotheses for the origin of the virus: some animal as a host; from an intermediary; frozen food and a laboratory accident.
For their part, scientists consider that the direct passage of the virus from a bat to humans is “unlikely” and about the laboratory accident, people considered it even more unlikely.
The strongest hypothesis in research is that the virus was transmitted to humans through an intermediary, in this case an animal, but research has yet to determine what it is. Experts have met with doctors and researchers from China, who were the first to confront and study the coronavirus.
