A SARS-like cluster of circulating bat coronaviruses shows potential for human emergence Medicine

The WHO says covid is no longer an emergency, yet does not say where covid originated from. No one knows. What I know is that covid is a cute name for SARS/Coronavirus. Something made in a lab at UNC Chapel Hill with Ralph Baric and his collegue from Wuhan China which he shared his gain of function research with. However the Nature article published in 2015 has this disclaimer, yet there is no animal origin after more than 3 years. So what do we believe?

“30 March 2020 Editors’ note, March 2020: We are aware that this article is being used as the basis for unverified theories that the novel coronavirus causing COVID-19 was engineered. There is no evidence that this is true; scientists believe that an animal is the most likely source of the coronavirus.”

The results indicate that group 2b viruses encoding the SHC014 spike in a wild-type backbone can efficiently use multiple orthologs of the SARS receptor human angiotensin converting enzyme II (ACE2), replicate efficiently in primary human airway cells and achieve in vitro titers equivalent to epidemic strains of SARS-CoV. ACE2 🤔

Ralph Baric, Vineet Menachery and colleagues characterize a SARS-like coronavirus circulating in Chinese horseshoe bats to determine its potential to infect primary human airway epithelial cells, cause disease in mice and respond to available therapeutics.
