A recent study, posted on the 29th of May, had revealed that the bats and pangolins had been infected by the novel coronavirus way before the deadly disease jumped to humans. Even though it was commonly believed that the virus originated from bats and the infected pangolins, which have been the ones that brought the virus to humans, researchers are suggesting that a third carrying species might have been involved in the infectious process. Therefore, they are suggesting that it is still early to suggest that pangolins are to blame for the ongoing pandemic.
The research was conducted by a team of analyzers from the Duke University in collaboration with the Los Almos National Laboratory, and their findings have been made public in the Science Advances journal. Their conclusions are stating that even though the virus was a product of mutations in bats, that have soon infected pangolins, a third species might be the one that infected humans.
The data collected was the sum of research conducted on 43 different genomes originating from three strains of COVID-19, and all of the results bear a striking resemblance to the deadly virus. Elena Giorgi, the leading staff scientists, working at the Los Almos National Laboratory, has declared that the primary objective of this study is to demonstrate the rich evolutionary history of SARS-CoV-2 and the way in which this virus managed to acquire the necessary genetic material to infect humans.
Their findings suggest that the current samples coming from pangolins are way too different from the RNA of coronavirus. Therefore, they are emphasizing on finding a third host that might be relevant for the transmission to humans. Consequently, the researchers have declared that even though we are still unsure about which is the third host of COVID019, the banning process of humans getting in contact with wild animals is crucial to prevent such a crisis from happening again.
