More than a year now entering into this pandemic, experts are still unsure about the origin of the deadly Corona Virus.
Many international scientists have come forward to say that they do not think that this virus is accidentally leaked from a Chinese lab and got so far.
A team of scientists from the World Health Organization did month-long research in Wuhan to find the exact source. They suspect that the virus must have probably jumped from the bats to humans with the help of some intermediator animal, most likely from a Chinese wildlife farm.
Also, the scientists stated the leaking of the virus from a lab is highly an unlikely event.
According to the Director-General of the organization, the scientists faced great difficulties in assessing the blood samples of the patients in and around Wuhan.
Moreover, World Health Organization was not working with the complete information. The experts in the UK, US, Switzerland, and Canada are not satisfied with the data collected by the World Health Organization.
On Friday, a letter was published in the Journal of Science in which the authors wrote, “Theories of accidental release from a lab and zoonotic spillover both remain viable.”
The two stories about the leakage of the virus, one Spillover from an animal and another is accidental lab leak, were not given equal considerations. This was written in the letter.
An immunologist from Stanford University School of Medicine thinks that the lab leak hypothesis has been dismissed by World Health Organization without proper investigation and careful assessment.
Questions are being raised on the Wuhan Institute of Virology for the lab leak as they are equipped with a high-level biosafety cabinet and even before pandemic studies were going on the Coronavirus.
But scientists are still figuring out that how it came out and also suggested that it might not be a lab leak since the new Coronavirus resembles those viruses in the bats.
