beatrice hahn is the scientist who do that work. so there are these diseases, the spillover, they are zoonotic. one other time i want familiar familiarizing what is -- a bubba lives in chemically and inconspicuously it occurs without causing mayhem. what causes that? and accommodation has evolved. the virus replicates. but it doesn't replicate cataclysmic we but slowly. it does not generally cause symptoms. it hides in its host and then something happens. humans come in contact with it somehow. the reservoir host gets into humans and then it becomes a zoonotic disease. one of the things that scientists do as they focus on these diseases, they identified the reservoir host. it's killing pick sellers and butchers. it's an isolated virus. the same virus in the human victims and pigs and this is a true case and it happened in 1998. then they went looking for the reservoir host. and they found it in large fruit flies. the disease was finally tracked through the spillover and here's what happened. people were cutting down malaysia for dev

michael wore the and beatrice hahn are the scientists who with their colleagues have done that work. there are these diseases. a spillover. they are zoonotic. one other slightly technical term by want to familiarize you with, reservoir host. the reservoir host is the kind of animal in which the bug, virus or whatever it is lives in chemically, permanently, in conspicuously, without causing disease, without causing mayhem in that particular creature. why does it live there? why does it live and on descriptively? probably because it is been in that species for millions of years and accommodation has evolved. a virus in its reservoir host replicates but it doesn't replicate cataclysmic we. it tends to replicate slowly and doesn't generally cause symptoms. it is invisible. it hides in its reservoir host and something happens, humans kill and eat that reservoir host, humans coming contact with it somehow. i will tell a couple stories how this can happen. reservoir host shed the virus and the virus gets into humans and becomes zoonotic. one of the things the scientists do as they study thi
