Biological weapons can be directed against crops and livestock, in addition to humans. The CDC separates potential bioterrorism agents that cause infections in humans into three categories, designated as A, B, and C [source: accessed 4/7/03].

Which are agents that could be used to create a biological disaster?

There are three basic groups of biological agents that could likely be used as weapons: bacteria, viruses and toxins. Biological agents can be spread by spraying them into the air, person-to-person contact, infecting animals that carry the disease to humans and by contaminating food and water.

What are biological weapons of mass destruction?

Biological weapons are microorganisms like virus, bacteria, fungi, or other toxins that are produced and released deliberately to cause disease and death in humans, animals or plants. Bioterrorism attacks could also result in an epidemic, for example if Ebola or Lassa viruses were used as the biological agents.

How are biological weapons used?

Sometimes known as “germ warfare,” biological weapons involve the use of toxins or infectious agents that are biological in origin. This can include bacteria, viruses, or fungi. These agents are used to incapacitate or kill humans, animals, or plants as part of a war effort.

How biological weapons are made?

Gene therapy involves repairing or replacing a gene of an organism, permanently changing its genetic composition. By replacing existing genes with harmful genes, this technique can be used to manufacture bioweapons (2).

What type of biological weapons are there?

Among the agents deemed likely candidates for biological weapons use are the toxins ricin, staphylococcal enterotoxin B (SEB), botulinum toxin, and T-2 mycotoxin and the infectious agents responsible for anthrax, brucellosis, cholera, pneumonic plague, tularemia, Q fever, smallpox, glanders, Venezuelan equine …

What are the most common biological weapons?

Along with smallpox, anthrax, plague, botulism, and tularemia, hemorrhagic fever viruses are among six agents identified by the Centers for Disease Control and Prevention (CDC) as the most likely to be used as biological weapons. Many VHFs can cause severe, life-threatening disease with high fatality rates.
