I was curious so I did a quick research on the previous SARS-CoV-1, the one that caused an outbreak back in 2003. Looks like they weren't able to find the natural reservoir for that one either. We did know it came directly from masked palm civets sold at local markets, but we don't know how those civets were infected. They were raised in farms, and no virus was found in those farms. And the closest natural match? WIV16 at 96.0%, again found on bats in Yunnan, again very far from Guangdong - where that outbreak started. So I think it must be because Yunnan has a lot of bats? that's why all the closest matches are found there?
