One way it can spread is through airborne spores, which are breathed in and settle into the lungs. The organism begins to multiply and excrete or secrete a bacterial toxin that causes inflammation. The incubation period can stretch up to 60 days. If you're having minor symptoms that you think are a cold, give it a little time. If they get worse call your health care provider.

Most of all, health experts stress anthrax is not contagious. It's very important to remind people that anthrax is not transmitted person to person.
