I had a theory around guano used for fertilizer acting as a fomite, but found some research an hour ago that suggests SARS doesn't remain viable via that route, so SARS-CoV-2 probably doesn't either.
Do we know that bats are the only (or only likely) nonhuman host? Was there a significant population of cases with a known connection to the lab?
Pangolins Malasia I think are the next closest source genetically. China imports from there as well as Africa for TCM so but the known strains from bats are still match much much better.
