What about biological agents used as weapons?

Let's see we have: Crimean-Congo Hemorrhagic Fever, Botulism, Glanders, Ebola, smallpox, and Typhoid fever.

That the new issue.

Biological agents have rapidly been exploited by Anti-American militia groups like Al-Queda for use as weapons.
And as American research expands looking for vaccines we face the problem of starting a bioweapons race with other nations, like the nuclear arms race with Russia during the cold war.
