No, definitely people wouldnt quarantine like that. But, H5N1 can have a really high mortality rate. From what I can tell, a near 100%. for birds and some marine mammals. I.e. every animal that catches it, dies.
Not to be macabre, but I don’t mean how long would people have to quarantine to beat back the virus. Im asking how long would an individual have to hide from everyone else, before everyone else, who refused to believe it was real, and whatnot, caught the virus and just…died.
