Cyanide Agent Treatment: Mild effects will generally resolve simply by removing the victim from the contaminated area and providing oxygenation. Severe effects require aggressive oxygenation as well as administration of IV hydroxocobalamin (Cyanokit). Sodium nitrate and sodium thiosulfate may also be used. Biologic Agents Primary types of biologic agents are viruses, bacteria and neurotoxins.

Dissemination is the means by which a terrorist will spread the agent. A disease vector is the animal carrying the disease. Incubation refers to the period between exposure and onset of symptoms. Viruses: Germs that require a living host to multiply and survive, and cannot survive outside of a host. Once inside, the body will invade healthy living cells and replicate and spread through the host. As the virus spreads, so does the disease it carries. Smallpox: Highly contagious disease. The last case was seen in 1977. Before rash and blister shows, the illness will start with a high fever and body aches and headaches. The patient’s temperature is usually in the range of 101-104. All lesions will be identical in development; will begin on the face and extremities and eventually move to the chest and abdomen. Viral Hemorrhagic Fevers: A group of diseases that include ebola, yellow fever, rift valley, among others. This group causes blood to seep out from tissues and vessels. Initially the patient will have flu-like symptoms and progress to internal and external hemorrhaging. Bacteria Unlike viruses, do not require a host to multiply and live Much more complex and larger than viruses and can grow up to 100x larger. Contain all the structures of a normal cell and are completely self-sufficient Can be fought with antibiotics Inhalation and Cutaneous Anthrax (Bacillus anthracis) Bacterium that lies dormant in a spore (protective shell). When exposed to the optimal temperature and moisture, the pathogen is released from the spore. Pulmonary anthrax is the deadliest and presents as a cold initially 82% death rate Plague- Bubonic/Pneumonic Killed more humans than any other infectious disease Natural vectors are infected rodents and fleas

Bubonic plague infects the lymphatic system, causing lymph nodes to become infected and grow, forming buboes. Can spread to the body, leading to sepsis and death Not contagious Pneumonic plague is a lung infection resulting from inhalation. Contagious with a much higher death rate than the bubonic plague Neurotoxins Deadliest substance known to man, 15,000 times more lethal than VX.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
