Biosafety Level 2

1. The four levels of security in a virology research facility are:
a. Biosafety level 1: Minimal biohazard. Study of low risk infectious agents: pneumococcus, salmonella.
b. Biosafety level 2: Moderate biohazard. Infectious agents: Hepatitis, Lyme disease, influenza.
c. Biosafety level 3: High biohazard. Multiple vaccinations required. Infectious agents: anthrax, typhus, H.I.V.
d. Biosafety level 4: Extreme biohazard. Maximum security. Infectious agents: Ebola, Lassa, Hanta viruses. Highly virulent, no known cures or vaccines.
2. The two methods of viral transmission shown in the video are:
a. Direct contact: the bacteria or virus is spread when an uninfected person is exposed to the body fluids (blood, semen, and saliva) of an infected person. The direct contact can be through kissing, sexual relation, touching oral secretion or body lesions. In the movie we see this happeing when the monkey spit on Jimbo, when Jimbo get to Boston and kisses his girlfriend, and when the lab technician by accident get contaminated blood on his face.
b.
Airborne: Direct contact is not necessary. The bacteria or virus are spread when people sneeze, laugh, exhale, or cough they can spread the bacteria or virus as they travel on dust particles or small respiratory droplets. In the movie, this is evidence when the patient who was in a different room got infected with the virus, and the people in the movie theater got infected when the sick man was coughing.
3. The hemorrhagic fever virus get from Africa to the United States when the “host” monkey is captured and ship in a boat to
