An efficient way to avoid being infected is good personal hygiene. Sunlight will kill many of these types of agents. For this reason, most incidents involving these types of agents occur inside or at night. Each agent has a natural host.

Anthrax is a naturally occurring bacterium in cattle, sheep and other hoofed animals.
