Coronavirus outbreak raises question: Why are bat viruses so deadly?




UC Berkeley
A new Berkeley study finds that bats’ fierce immune response to viruses could drive viruses to replicate faster, so that when they jump to mammals with average immune systems, such as humans, the viruses wreak deadly havoc.

Many of the bat viruses jump to humans through an animal intermediary. SARS got to humans through the Asian palm civet; MERS via camels; Ebola via gorillas and chimpanzees; Nipah via pigs; Hendra via horses and Marburg through African green monkeys. Nonetheless, these viruses still remain extremely virulent and deadly upon making the final jump into humans.

The researchers note that disrupting bat habitat appears to stress the animals and makes them shed even more virus in their saliva, urine and feces that can infect other animals. 🦇#BerkeleyResearch https://news.berkeley.edu/…/coronavirus-outbreak-raises-qu…/

The immune systems of some bats are so fierce that they drive viruses to a virulence that proves deadly when they cross over into humans
