Question: What Is The Primary Distinction Between Category A And Category B Biological Agents?

Category A consists of the agents that are considered the highest risk, and much of the biodefense research effort is directed towards these agents. Included among Category B agents are ones that could conceivably threaten water and food safety. New high-risk pathogens may be added to the list as they are discovered.

What are Category A agents?

Bioterrorism agents can be separated into three categories, depending on how easily they can be spread and the severity of illness or death they cause. Category A agents are considered the highest risk and Category C agents are those that are considered emerging threats for disease.

What are the three categories of biological agents?

The United States Center for Disease Control (CDC) has divided the agents which can be used as biological weapons into three categories, Category A, B, and C. Though these agents are rarely seen in the United States, we must prepare for them because they pose the greatest risk to our national security.

What is a Category A biological substance?

A Category A substance is an infectious substance that is transported in a form that, when exposure to it occurs, is capable of causing permanent disability, or a life-threatening or fatal disease in otherwise healthy humans or animals.

What are Category C biological agents?

Classification of Bioterrorism Agents Category C includes pathogens that are considered emerging infectious disease threats and which could be engineered for mass dissemination.

Which category of biological agents includes agents that have some potential for dissemination as well as agents of concern for food and water safety?

Category C Biological agents that have undergone some development for widespread dissemination but do not otherwise meet the criteria for Category A, as well as several biological agents of concern for food and water safety, are included in this category.

What are the major categories of biological threats?

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 is the basis of classifying biological factors to particular groups?

All living organisms are classified based on basic, shared characteristics. Organisms within each group are then further divided into smaller groups. These smaller groups are based on more detailed similarities within each larger group.
