Coronavirus (COVID-19): Why are bat viruses so deadly?

The video discusses how bats' strong immune responses allow them to host viruses without getting sick, which may cause viruses to spread more quickly within them. When these viruses jump to other mammals, including humans, they can cause severe illness. Researchers conducted experiments on bat cells and used mathematical models to understand virus spread. Future research aims to develop formal models of virus evolution and bat immune systems to better understand the effects on other animals and humans.
