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.

What is the believed origin of the coronavirus pandemic discussed in the video?

• Birds

How do bats manage to host viruses without falling ill?

• They have a slow immune response.

• They have a fierce immune response.

• They avoid viruses altogether.

• They have no immune response.

What happens when viruses jump from bats to other mammals?

• They cause no effect.

• They become less harmful.

• They disappear.

• They cause deadly havoc.

What did researchers use to study the virus spread in bats?

• Computer simulations

• Historical data

• Mathematical models

• Field observations

What is the next step in the research on virus evolution in bats?

• Developing a vaccine
