Screening species with serology though I think is the way to go - that is why Lin-Fa's ACE2BOB makes sense - find the species that have antibodies then trap the hell out of them until you get lucky and hit one at peak viremia/RNA.

    Yeah, culturing viruses from bats or any other animal = bloody hard. I wouldn't be surprised that if you had 50 bats all infected with SC2, you'd only be able to grow it out of one of those.

    Explains some of the problems in the diagnostic space - Start mixing in detection with antigen assays [which correlates not so well with infectious virus or RNA] and it gets complicated fast.

    But that means these ideas about WIV sampling viruses from the wild and one of the accidentally escapes might bewrong?

    I think most of those people underestimate how incredibly hard it is to grow stuff from such samples, yes.

    I think they assume - 10,000 samples = 10,000 chances for SC2 to hop out of a tube. Nope.

    @Andrew Rambaut Hammer hits nail!

    There's virtually _zero_ chance a virus could leak out of a tube - if they culture to high titers, sure - but again, in most circumstances that's not going to be possible because it's so hard to grow anything out of a primary sample.

    That and they should be doing it with at least an N95 and better yet a PAPR. Damn sure have my ppl in a PAPR/class 2 hood if they are trying to grow virus in large amts.
