1. We should let scientists to do research and investigate.
2. Check current research from Cambridge University. https://www.cam.ac.uk/research/news/covid-19-genetic-network-analysis-provides-snapshot-of-pandemic-origins
Probably we need to wait for WHO final research.
Brief: Forster and colleagues found that the closest type of COVID-19 to the one discovered in bats – type ‘A’, the “original human virus genome” – was present in Wuhan, but surprisingly was not the city’s predominant virus type.
Versions of ‘A’ were seen in Chinese individuals, and Americans reported to have lived in Wuhan, and mutated versions of ‘A’ were found in patients from the USA and Australia.
Wuhan’s major virus type, ‘B’, was prevalent in patients from across East Asia. However, the variant didn’t travel much beyond the region without further mutations – implying a 'founder event' in Wuhan, or 'resistance' against this type of COVID-19 outside East Asia, say researchers.
