Virus Hunting - What's the Point of the Programme?
The whole point of the programme is to identify which viruses might spill over and cause future pendemics. There's four key classes of experiments that you perform on an animal virus to determine whether it's a good candidate for causing a pandemic inhumans. You want to know, how tightly does this virus bind to human target cells, how readily does it actually infect those cells,. How readily does the backbone of the virus licate and churn out new copies of the virus irrelevant human tissue types. And because you can't test it in humans, of course, how readily is it transmitted in animal models chosen for their similarity to humans.
