How many biological agents are there?
A biological agent is an infectious disease. They can be naturally occurring or be used in biological warfare. There are more than 1200 different kinds of biological agents, some of which can be used as biological weapons.
What are biological agents that cause disease?
Biological agents include viruses, bacteria, fungi and parasites, and they can cause health problems either directly or through exposure to related allergens or toxins. Work-related exposure to biological agents may be associated with several health problems, including infectious diseases, cancer and allergies.

Is chlorine a biological agent?
It’s really very important to have clean water to avoid water borne diseases. But chlorine is a chemical agent that effects the eyes and the ability to breath. When mixed with water it produces hydrochloride acid. It’s not a very efficient chemical weapon because we can sense it when it’s not very toxic yet.
What are some examples of biological weapons?
Historical biological weapons programmes have included efforts to produce: aflatoxin; anthrax; botulinum toxin; foot-and-mouth disease; glanders; plague; Q fever; rice blast; ricin; Rocky Mountain spotted fever; smallpox; and tularaemia, among others.
Are toxins a biological agent?
The CDC categorizes natural toxins as biological agents even though there is some overlap with man-made chemical agents (toxicants). However, natural toxins are usually more toxic than chemical agents, have a longer latency period, and they are associated with a lower risk of environmental contamination [5, 6].

Is smallpox a biological agent?
No one has gotten smallpox naturally since 1977. However, it is possible that variola virus (the virus that causes smallpox) could be used in a biological attack (an intentional release of viruses, bacteria, or other germs that can sicken or kill people, livestock, or crops).
