How many categories of bioterrorism are classified by the CDC?
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.
Which are examples of Category B bioterrorism agents or disease?
- Brucellosis (Brucella species)
- Epsilon toxin of Clostridium perfringens.
- Food safety threats (e.g., Salmonella species, Escherichia coli O157:H7, Shigella)
- Glanders (Burkholderia mallei)
- Melioidosis (Burkholderia pseudomallei)
- Psittacosis (Chlamydia psittaci)
- Q fever (Coxiella burnetii)
Which are types of bioterrorism agents?
- Anthrax (Bacillus anthracis)
- Botulism (Clostridium botulinum toxin)
- Plague (Yersinia pestis)
- Smallpox (variola major)
- Tularemia (Francisella tularensis)
- Viral hemorrhagic fevers, including. Filoviruses (Ebola, Marburg) Arenaviruses (Lassa, Machupo)
What are the categories of disasters in healthcare?
Each type of threat has unique characteristics and medical impacts:
- Chemical. A chemical emergency occurs when a hazardous chemical has been released, and the release has the potential to harm people’s health.
How does the CDC categorize biologic 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 are the 4 types of disasters?
Types of Disaster[edit | edit source]
- Geophysical (e.g. Earthquakes, Landslides, Tsunamis and Volcanic Activity)
- Hydrological (e.g. Avalanches and Floods)
- Climatological (e.g. Extreme Temperatures, Drought and Wildfires)
- Meteorological (e.g. Cyclones and Storms/Wave Surges)
What is a Category A potential bioterrorism agent?
Potential bioterrorism agents by category. Category A agents. Variola major (smallpox) Bacillus anthracis (anthrax) Yersinia pestis (plague)
What are the four types of biological agents?
Biological agents include bacteria, viruses, fungi, other microorganisms and their associated toxins.
What is a Category 3 pathogen?
WHO Risk Group 3 (high individual risk, low community risk) – A pathogen that usually causes serious human or animal disease but does not ordinarily spread from one infected individual to another. Effective treatment and preventive measures are available.
What is a Category 2 pathogen?
Human pathogens – Class of risk 2 : micro-organisms that can cause human disease and might be a hazard for directly exposed persons; they are unlikely to spread to the community. There is usually effective prophylaxis or treatment available.
What are the 3 categories of natural disasters?
Natural hazards also fit into three categories that describe the speed and extent of a hazard: catastrophic hazards, rapid onset hazards, and slow onset hazards.
What is disaster classification?
The new classification distinguishes two generic disaster groups: natural and technological disasters. The natural disaster category being divided into six disaster groups: Biological, Geophysical, Meteorological, Hydrological, Climatological and Extra-Terrestrial.
How many categories are there of biological agents?
There are more than 1200 different kinds of biological agents, some of which can be used as biological weapons. 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.
What are Category 4 pathogens?
Biohazard Level 4 usually includes dangerous viruses like Ebola, Marburg virus, Lassa fever, Bolivian hemorrhagic fever, and many other hemorrhagic viruses found in the tropics.
What are the 4 hazard groups?
The four hazard groups of human pathogens and the basis of their classification are as follows….Classification of Human Pathogens
- Ability to cause infection.
- Severity of the disease that may result.
- Risk that infection will spread to the population.
- Availability of vaccines and effective treatment.
