BSL-2, or Biosafety Level 2, refers to a level of biosafety that applies to agents that pose moderate hazards to personnel and the environment. These agents are typically associated with human disease but are rarely fatal and have effective treatments available.
Here are some examples of BSL-2 diseases:
- Hepatitis B virus: A viral infection that affects the liver.
- Salmonella: A bacterial infection causing food poisoning.
- Staphylococcus aureus: A bacterium that can cause skin infections, pneumonia, and other illnesses.
- HIV: The virus that causes AIDS.
- Influenza: A respiratory illness caused by a virus.
- Measles: A highly contagious viral infection.
- Rubella: A viral infection that can cause birth defects.
These diseases are considered BSL-2 because they are:
- Moderately hazardous: While they can cause serious illness, they are not typically fatal.
- Treatable: Effective treatments are available for most BSL-2 diseases.
- Transmitted through various routes: They can be spread through contact with bodily fluids, contaminated surfaces, or airborne droplets.
It's important to note that BSL-2 diseases are not always easily contained, and proper safety precautions are crucial in research and healthcare settings to prevent their spread.
