What can you do to protect yourself against a bioterrorist threat? Here are some of the practical (and obvious) measures that one can take in case of biological attack:
The US Centers for Disease Control and Prevention (CDC) classifies various diseases into 4 levels. Level 1 has the minimum risk and Level 4 has the highest.
Includes: Bacillus subtilis, canine hepatitis, E. coli, varicella (chicken pox).
At Level 1, precautionary measures against the biohazardous materials in question are minimal, most likely involving gloves and facial protection. Decontamination procedures are similar to modern precautions against everyday viruses, such as washing ones hands with anti-bacterial soap and washing all exposed surfaces of the lab with disinfectants.
Includes: Hepatitis B, hepatitis C, influenza, Lyme disease, West Nile virus, salmonella, scrapie.
Anthrax, BSE, HIV, mumps, SARS, smallpox, tuberculosis, typhus, Yellow fever.
Includes: Bolivian fever, Dengue fever, Ebola, Hanta virus, Lassa virus, and other various hemorrhagic diseases mostly from Africa
At this level, the use of a space suit and a self-contained oxygen supply is required. The entrance and exit of a Level 4 biolab will contain multiple showers, a vacuum room, an ultra-violet light room, and other safety precautions designed to destroy all traces of the biohazard. Multiple airlocks are employed and both doors are prevented from opening at the same time through an electronic security system. Air and water service originating and exiting from a Level 4 biolab will undergo similar decontamination procedures to prevent accidental release of the biological agent.
