Ebola and Bats
According to National Geographic, bats may be the natural reservoir for Ebola. That is, bats might be the carriers for one of the most contagious diseases known to man. The disease requires a host besides primates to survive since it quickly kills 50 to 90 percent of its victims through massive internal bleeding. So far, there is no cure.
The article doesn’t speculate on next steps, but if bats were confirmed to be a natural reservoir for Ebola (and were the only such reservoir), it would be possible to eliminate the disease. Ideally a bat vaccination could be developed or even a strain of bats that wouldn’t carry it. Time will tell.
