In their study, reported on the open-access site PLOS Biology , the group used data from past research efforts to model the growth of viruses within bat populations as well as their spread to other animals. Prior research has shown that when a virus jumps from bats to humans, the results can be deadlier for humans than when viruses jump from other mammals. The reason has been a matter of debate. In this new effort, the team used data from prior research efforts , along with m
