How does HIV work a level?
If a person with HIV exchanges bodily fluid with another person, HIV can infect the second individual and will be present in their bloodstream.
The HIV virus uses its attachment proteins to enter human immune cells (specifically the T helper cell) by binding to receptors on the T cell..
How is HIV-2?
HIV-2 is an enveloped retrovirus that causes infection in humans, similar to HIV-1.
It is endemic to parts of West Africa, but globalization has led to worldwide spread.
It is estimated that 1 to 2 million people live with HIV-2, and without treatment, infection invariably leads to significant morbidity and mortality..
What are biosafety level 2 pathogens?
If you work in a lab that is designated a BSL-2, the microbes there pose moderate hazards to laboratorians and the environment.
The microbes are typically indigenous and associated with diseases of varying severity.
An example of a microbe that is typically worked with at a BSL-2 laboratory is Staphylococcus aureus..
What diseases are covered by BSL-2 lab?
Biosafety Level 2 (BSL2) practices, equipment, and facility design are applicable to clinical, diagnostic, teaching, and other laboratories in which work is done with moderate-risk agents that are present in the community and associated with human.
Hepatitis B virus, HIV, the salmonellae, and Toxoplasma spp..

What is biosafety level 2 used for?
BSL-2 laboratories are used to study moderate-risk infectious agents or toxins that pose a moderate danger if accidentally inhaled, swallowed, or exposed to the skin.
Design requirements for BSL-2 laboratories include hand washing sinks, eye washing stations, and doors that close and lock automatically..
What is level 2 HIV?
The second stage of HIV infection is chronic HIV infection (also called asymptomatic HIV infection or clinical latency).
During this stage, HIV continues to multiply in the body but at very low levels.
People with chronic HIV infection may not have any HIV-related symptoms..
Where is HIV type 2 found?
HIV-2 infection is predominantly found in West African nations, such as Guinea-Bissau, The Gambia, Senegal, Cape Verde, Cote d'Ivoire, Mali, Sierra Leone, and Nigeria..
- While BSL-2 labs are safe enough for serious viruses like HIV and Staphylococcus aureus, BSL-3 level labs are required for potentially airborne diseases.
