Egyptian fruit bats

Scientists are quite sure these bats can carry Marburg virus, which causes a hemorrhagic fever in humans, which is like Ebola virus disease. In fact Marburg & Ebola viruses are related.

By 'carry', scientists mean that bats get infected with the virus but don't become nearly as ill as humans. Then they can pass the virus on to humans in several ways, such as by their fecal droppings. Once infected, humans pass it to other humans by body secretions such as blood.

Not surprisingly, bats that carry Marburg virus are related to bats that carry Ebola virus. Both viruses are found in Africa & are very dangerous. Different kinds of bats can carry other dangerous viruses, such as rabies, Nipah & Hendra viruses. (Most of the time, humans get rabies from wild animals or dogs). Bats can be involved in passing on other diseases. E. ., they can pass on the fungus that causes lung disease histoplasmosis,
