Isolates obtained from pangolins seized in Guangdong were only 92% identical in sequence to the SARS-CoV-2 genome, a number that is too low for the pangolin virus to be an intermediate host. Scientists have found coronaviruses related to SARS-CoV-2 circulating in bats across many parts of Asia and also pangolin virus that could potentially infect humans. Many animals are capable of transmitting viruses to other species, and nearly all strains of the coronavirus contagious to humans originated in wildlife. Identifying SARS-CoV-2-related coronaviruses in Malayan pangolins. But it may be about the best scientists can do to refute the “non-natural original” theory. However, some fare better than others - the Russian Sputnik jab … Published online February 3, 2020.

The S1 protein of Pangolin-CoV is much more closely related to SARS-CoV-2 than to RaTG13. These are … There is no evidence suggesting either bats or pangolins were the origin host of the novel coronavirus , one of China’s top health experts told European diplomats in Beijing last week.

A pneumonia outbreak associated with a new coronavirus of probable bat origin. 2020 Apr 20;30(8):1578. doi: 10.1016/j.cub.2020.03.063. Liu P., Chen W., Chen J.-P. A pangolin is a small mammal covered in sharp plates—a sort-of pinecone with legs and a tongue, an army tank that triggers a cuddle reflex. Both Pangolin-CoV and RaTG13 lost the putative furin recognition sequence motif at S1/S2 cleavage site that can be observed in the SARS-CoV-2. Based on the research in our lab, we believe that pangolins, as opposed to snakes, may have served as the hosts that transmitted the coronavirus to people and caused the ongoing COVID-19 pandemic. 2020;395:497–506. We are a team of bioinformaticians and we feel it is our responsibility to the global community to investigate the origin of this virus.

Colloquially known as simply the coronavirus, it was previously referred to by its provisional name, 2019 novel coronavirus (2019-nCoV), and has also been called human coronavirus 2019 (HCoV-19 or hCoV-19). Bats are known carriers of the latest strain of the disease, which has infected at least 31,000 people and killed more than 630 worldwide, mostly in China where the outbreak originated. A tiny protein of SARS-CoV-2, the coronavirus that gives rise to COVID-19, may have big implications for future treatments, according to a team of Penn State researchers. Aside from RaTG13, Pangolin-CoV is the most closely related CoV to SARS-CoV-2. Since its initial outbreak at Huanan Seafood Wholesale Market in Wuhan, China, in late 2019, COVID-19 has since infected more than a million people across the globe. 3245. 2020 Mar 15;16(10):1678-1685. doi: 10.7150/ijbs.45053.
