What are the chances of biological warfare?

First, the filoviruses are highly lethal, causing severe hemorrhagic fever disease in humans and apes with high mortality rates (up to 90%).
What type of weapon is Ebola?
Ebola as a Biological Weapons Agent As a biological weapons agent, the Ebola virus is feared for its high case-fatality rate. Because of its rarity, the disease may not be diagnosed corrected at the onset of an outbreak.
