A team from China’s top science institution, the Chinese Academy of Sciences in a paper claims that SARS-CoV-2 likely originated in India in the summer of 2019.
According to Chinese scientists, Wuhan is the place where the first human to human transmission of SARS-CoV-2 occurred.
Before the virus had spread to Wuhan, it had already seen some evolution in the previous transmission between humans, says the paper.
According to the study published in a paper by researchers at the Shanghai Institute for Biological Sciences, the coronavirus spread across several countries and China was the first one to detect it.
The Chinese scientists further claim that the coronavirus entered humans through contaminated water by animals.
According to the paper, scientists used a method called phylogenetic analysis. It is a technique where scientists study the mutation of the virus to trace the origins of Covid-19.
