Biological Attacks

•A biological attack is an attack using toxic chemicals and contagious diseases as weapons of war.

A terrorist group is more likely to use different

weapons in an attack.

First of all, it is impossible to predict with certainty what approach someone or group might use.

WHAT ARE NERVE AGENTS???

• CHEMICALS THAT AFFECT THE NERVOUS SYSTEM. • HENCE THE NAME-NERVE AGENTS

• NERVE AGENTS ARE SIMILAR TO INSECTISIDES—WHICH CAN BE

DEADLY IF EXPOSED

• Breathing a lethal dose of these chemicals can kill in 15 minutes; A lethal dose on the skin can kill in only 1-2 minutes!! To get an idea of how deadly these chemicals are, you do the math.

NAME

• They can be released using bombs, missiles, spray tanks, rockets and landmines. VX is the most deadly and Tabun is the least deadly (although still very hazardous). Nerve agents are more dense than air so they

are especially dangerous to people in low areas.

• Nerve agents are clear and may have no odor. Similar to Carbon Monoxide. They are extremely dangerous and can enter the body

through the air or contact with the skin.

Treatment for Nerve Agent Exposure

• Immediate treatment of a person who has been exposed to a nerve agent exposure includes a complete washing of the eyes and skin with water. A diluted (5%) bleach solution should also be applied to the skin if possible.

Atropine & Pralidoxime Chloride

• Have been used for antidotes.• Atropine works by blocking one type of

acetylcholine receptor so that the acetylcholine that is already in the synapse cannot work.

• Pralidoxime works by blocking the binding of the nerve agent to the AChE.

• Diazepam AKA Valium may be used to reduce convulsions andseizures brought on by exposure to nerve agents.

NERVE AGENTS

Category A Diseases/AgentsThe U.S. public health system and primary healthcare providers must be prepared to address various biological agents, including pathogens that are rarely seen in the United States. High-priority agents include organisms that pose a risk to national security because theycan be easily disseminated or transmitted from person to person; result in high mortality rates and have the potential for major public health impact; might cause public panic and social disruption; and require special action for public health preparedness.

Category A, Agents include:

Anthrax (Bacillus anthracis)Botulism (Clostridium botulinum toxin) Plague (Yersinia pestis) Smallpox (variola major) Tularemia (Francisella tularensis) Viral hemorrhagic fevers (filoviruses [e.g., Ebola, Marburg] and arenaviruses [e.g., Lassa, Machupo])

ANTRAX• This is most likely during terror

attacks

• Remember the outbreak after 9/11

• Antrax is a bacteria known as Bacillus anthracis

• Skin anthrax and inhalation anthrax

SIGNS & SYMPTOMS

• First appers in 1-5 days as a small pimple-looking sore that progresses.

• Fever

• You may feel fatigued

CONTAGIOUS DISEASE

• SMALLPOX

• BUBONIC PLAGUE

SMALLPOX

• IS A VIRUS

• Variola is the virus that causes smallpox.

• Two types– Variola Major - the most sever form– Variola Minor - a milder form

Signs & Symptoms

• High fever

• Headaches and Body Aches

• Chills

• Hallucinations

• Vomiting

• Abdominal and Back Pain

• Rash

Treatment

• Isolation

• Vaccination

• Treatment is mainly to help relieve symptoms

• BIOLOGICAL AGENTS CAN BE DISSEMINATED IN VARIOUS WAYS.

• Through the air by aerosol sprays

• Used in explosives (artillery, missiles, detonated bombs)

• Put into food or water

• Absorbed through or injected into the skin

How to Recognize a

Biological Attack

• Smell in the air

• Experiencing different symptoms

• It is dark

• You see gas clouds

• Explosions

• You might hear of attack via radio, TV, sirens, etc.

PREPARING FOR

• ASSEMBLE A DISASTER SUPPLY KIT. IT NEEDS TO INCLUDE:

• NON-PERISHABLE FOOD AND DRINKING WATER.

• A ROLL OF DUCT TAPE AND SCISSORS

• PLASTIC FOR DOORS, WINDOWS AND VENTS FOR THE ROOM IN WHICH YOU WILL SHELTER, (THIS SHOULD BE AN INTERNAL ROOM WHERE YOU CAN BLOCK OUT AIR THAT MAY CONTAIN HAZARDOUS CHEMICAL OR BIOLOGICAL AGENTS).

• FIRST AID KIT

• SANITATION SUPPLIES INCLUDING SOAP, WATER AND BLEACH.

PROTECTIVE MEASURES

• Masks: Military gas mask or high-efficiency particulate air (HEPA) filter masks

• Clothing: Most biological agents in the air do not penetrate unbroken skin, and few stick to skin or clothing

• Medical Protection:

• Antibiotics: Orally or through an IV, even before specific agent is Identified

• Vaccinations: Available for anthrax, botulinum toxin, tularemia, plague, Q fever, and smallpox
