A single amino acid mutation within the spike protein of a bat coronavirus can enable the virus to bind to human ACE2 receptors, facilitating the transition from animal-to-animal transmission to human infection. This genetic change, occurring in the receptor-binding domain (RBD), allows the virus to recognize and enter human cells more effectively, a process known … Read more
