-Anthrax itself is not a bioengineered organism, but a naturally occurring bacterium in Nature (B anthracis) that was weaponized almost 80 years ago.
-Anthrax can remain in dormant in the form of spores for decades or centuries.
-There are three forms of anthrax infections – Cutaneous- infection of the skin, Gastrointestinal- infection of the intestinal tissue, and finally the deadliest, as well as the most infamous form; Inhalation anthrax.
-Any form of anthrax can be effectively treated with antibiotics. If caught early enough the treatment is curative.
-Anthrax is not contagious.
The nature of anthrax is a bacterium that utilizes a form of spores to remain viable for extended periods of time. The spores usually reside in loose grass and soil. Transmission of Anthrax to humans was recorded thousands of years ago with livestock handlers, who caught the disease from their cattle who had sores residing in their coats. Even when those animals died and were buried, the spores on their corpses would reside in the soil for decades or centuries, unearthing those areas of soil can still be dangerous and risk infection.
Despite this, cases of natural anthrax infection are few and far between, with modern antibiotics the threat of anthrax is minimal.
Information on Anthrax was gathered from the CDC website Anthrax section.
