We found that compared with SARS CoV and sars-cov-2, the fusogenic degree of ratg13 spike (s) protein was significantly reduced, and 7 of the 16 different ace2s served as entry receptors for all three viruses, indicating that these three viruses may have a wide host range.

Scientists are tirelessly identifying the animal in the hope of eradicating the spread, but so far, no one is sure.

In fact, bat ratg13 cov binds to ACE2 and contains a similar four residue motif in the ACE2 binding ridge of RBM, suggesting that sars-cov-2 may have evolved from ratg13 or unknown related bat cov.

More and more studies have shown that sars-cov-2 coronavirus may appear in the population earlier than the first confirmed infection.
