A team of researchers from China’s Shanghai Institute for Biological Sciences have claimed that the SARS-CoV-2 coronavirus existed in India and Bangladesh long before the outbreak of the COVID-19 pandemic in Wuhan in December last year.
 
In a study titled “The early cryptic transmission and evolution of Sars-Cov-2 in human hosts,” the Chinese researchers claimed the traditional approach to tracing the origin of the virus was flawed, reports UK-based newspaper The Sun.

Most scientists are using a bat virus discovered in Yunnan province of China several years ago as an ancestral reference to the coronavirus, but the bat virus is not the ancestor of coronavirus, the research paper claims.
