What are the 3 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.
Is anthrax a biological agent?
Anthrax as a weapon Biological agents are germs that can sicken or kill people, livestock, or crops. Anthrax is one of the most likely agents to be used because: Anthrax spores are easily found in nature, can be produced in a lab, and can last for a long time in the environment.

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.
Is anthrax still a threat?
Anthrax is a potential biological terrorism threat because the spores are resistant to destruction and can be easily spread by release in the air. Anthrax as a bioweapon is a science fiction in the past.
Can you survive anthrax?
Inhalation anthrax is considered to be the most deadly form of anthrax. Infection usually develops within a week after exposure, but it can take up to 2 months. Without treatment, only about 10 – 15% of patients with inhalation anthrax survive. However, with aggressive treatment, about 55% of patients survive.
Is a virus a biological agent?
Biological agents are widely found in the natural environment and as a result found in many work sectors. They include bacteria, viruses, fungi (including yeasts and moulds) and internal human parasites (endoparasites). The majority of these agents are harmless however some may have potential to cause ill health.
Is a virus biological material?
Viruses are by far the most abundant biological entities on Earth and they outnumber all the others put together. They infect all types of cellular life including animals, plants, bacteria and fungi.
What biological agent is extremely lethal?
Botulinum toxins pose a major threat as biological weapons because they are extremely potent and lethal; some of the toxins are relatively easy to produce and transport; and people with botulism require prolonged intensive hospital care.
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 are the implications of anthrax?
The most serious complications of anthrax include: Your body being unable to respond to infection normally, leading to damage of multiple organ systems (sepsis) Inflammation of the membranes and fluid covering the brain and spinal cord, leading to massive bleeding (hemorrhagic meningitis) and death.
What does it mean for a pathogen to be weaponized?
When biological agents are made into or used as a weapon or as a potential weapon they are being weaponized.
What is the deadliest biological weapon?
Bacillus Anthracis (Anthrax) Bacillus anthracis bacteria, which causes anthrax, is one of the most deadly agents to be used as a biological weapon.
Is there a vaccine for anthrax?
There is a vaccine that can help prevent anthrax, a serious infection caused by the bacterium Bacillus anthracis. However, this vaccine is not typically available for the general public. It is only recommended for people who are at an increased risk of coming into contact with or have already been exposed to B.
When was anthrax first weaponized?
The first mass use of anthrax spores as a weapon is said to have taken place during the Japanese occupation of China from 1932 to 1945.
What are the 4 types of pathogens?
Pathogenic organisms are of five main types: viruses, bacteria, fungi, protozoa, and worms.
Whats is Ebola?
Related Pages. Ebola Virus Disease (EVD) is a rare and deadly disease in people and nonhuman primates. The viruses that cause EVD are located mainly in sub-Saharan Africa. People can get EVD through direct contact with an infected animal (bat or nonhuman primate) or a sick or dead person infected with Ebola virus.
What are different types of disease?
There are four main types of disease: infectious diseases, deficiency diseases, hereditary diseases (including both genetic diseases and non-genetic hereditary diseases), and physiological diseases. Diseases can also be classified in other ways, such as communicable versus non-communicable diseases.
What is an example of a Category A substance?

The most significant biological attack in the United States (US) was the intentional contamination of restaurant salad bars with Salmonella by a religious cult in Oregon in 1984 [2]. In September 2001, the American public was exposed to anthrax spores as a bioweapon delivered through the US postal system.
How common is bioterrorism today?
Bioterrorism is rare and is used to threaten people, governments, and countries. In bioterrorist attacks, usually only a small number of people may be injured or affected. However, many more become afraid.
Is Ebola considered bioterrorism?
Ebola threat as bioterrorist attack The virus is classified as category A bioterrorism threats by Centers for Disease Control and Prevention (CDC) for several reasons [1]. First, the filoviruses are highly lethal, causing severe hemorrhagic fever disease in humans and apes with high mortality rates (up to 90%).

Anthrax is a rare infectious disease caused by the bacterium Bacillus anthracis. Anthrax occurs naturally around the world in wild and domestic hoofed animals, especially cattle, sheep, goats, camels and antelopes.
Who created anthrax?
Discovery. Robert Koch, a German physician and scientist, first identified the bacterium that caused the anthrax disease in 1875 in Wollstein (now Wolsztyn – a town in Poland). His pioneering work in the late 19th century was one of the first demonstrations that diseases could be caused by microbes.
Can humans get anthrax from cattle?
Anthrax is primarily a disease of herbivores, particularly bison and beef cattle. Anthrax is not highly contagious (i.e. is not typically passed from animal to animal). Anthrax infections are rare in humans.

What are the four biosafety levels?
Activities and projects conducted in biological laboratories are categorized by biosafety level. The four biosafety levels are BSL-1, BSL-2, BSL-3, and BSL-4, with BSL-4 being the highest (maximum) level of containment.
