History, and math, tell us that the Ebola virus spreads exponentially quickly. This means Ebola is a global problem and all nations need to rally -- to stop the epidemic fast.

Bats are the only mammals capable of true flight. Scientists believe flight may influence their immune responses to coronoviruses, which cause fatal diseases such as SARS and MERS in humans.
Scientific studies show that bats may carry "coronoviruses" causing SARS and MERS - without showing symptoms of disease. Could the bat immune system be key to human survival in future pandemics?
