  > Southeast Asia, where bats/pangolins are originally from, Bats been all over the world much longer than humans have [1]. Pangolins are widespread across Asia and Africa, and have been for 10s of millions of years [2] > also might have been exposed to milder coronaviruses in the past (common cold, etc). The whole planet has been exposed to milder coronaviruses in the past and present - that's the "common" part. They are so common that they are a confounding factor in the current COVID19 antibody tests, thus reducing the confidence of a positive test result in areas that don't have a known outbreak. 1. https://link.springer.com/article/10.1007/s10914-005-6945-2#:~:text=The%20phylogenetic%20and%20geographic%20origins,Europe%2C%20Africa%2C%20and%20Australia https://link.springer.com/article/10.1007/s10914-005-6945-2#.... 2. https://en.m.wikipedia.org/wiki/Pangolin https://en.m.wikipedia.org/wiki/Pangolin
