    USA Today online has an article saying a WHO delegation of 13 scientists from 10 countries determined in China a thumb size bat started this epidemic.

    The article was in yesterday’s USA main page. Changes daily, no idea how to recover. Sorry

    A determination has not yet been made. I found the link to the article.

    "There's really not a clear tree where we have forensic evidence to point to exactly where it came from," said John Connor, a virologist at Boston University who studies emerging infectious diseases. "It looks like it's a bat-derived virus, and there's a big question mark after that."

    This week, a World Health Organization delegation of scientists from 10 different nations finally was allowed in the country to explore the virus' origins.

    The group of related coronaviruses giving rise to SARS-CoV-2 has existed for decades in bats and likely originated more than 40 years ago, said Dr. Charles Chiu, a professor and expert in viral genomics at the University of California, San Francisco.

    SARS-CoV-2 shares 96% of its genetic material with a sample of coronavirus taken in 2013 in Intermediate Horseshoe bats from Yunnan province in China, which suggests the Yunnan virus is its ancestor. How the virus traveled the 1,200 miles from Yunnan to Wuhan remains unknown.

    Because the 2013 sample is the only one available, scientists had to undertake genetic analysis to estimate when the bat strain and the strain now circulating among humans diverged. They put the split sometime in the 1960s or 1970s, said Maciej Boni, a professor of biology at Pennsylvania State University's Center for Infectious Disease Dynamics, who spent almost a decade working in Asia.

    Also found this, but it was a while ago "Bioinformatic analyses indicated that the virus had features typical of the coronavirus family and belonged to the Betacoronavirus 2B lineage. Alignment of the full-length genome sequence of the COVID-19 virus and other available genomes of Betacoronavirus showed the closest relationship was with the bat SARS-like coronavirus strain BatCov RaTG13, identity 96%."

    Your article quotes "How the virus traveled the 1,200 miles from Yunnan to Wuhan remains unknown." I guess they flew (even if none flew 1200 miles, they passed it on like the baton in a relay).

    I now know where the saying, “A bat out of hell” came from

    It was found inside a meatloaf.

    Maybe Ozzy Osbourne toured China?
