Difference between biosafety level 1 and 2

  • What are the biological safety levels 1 and 2?

    Biosafety Level 2 (BSL-2) builds upon BSL-1.
    BSL-2 is suitable for work with agents associated with human disease and pose moderate hazards to personnel and the environment..

  • What are the biological safety levels 1 and 2?

    BSL-3 involves handling indigenous or exotic agents that may cause serious or potentially lethal diseases through inhalation and/or pose a serious threat to the environment.
    Compared with the BSL-2 lab, BSL-3 labs require additional security precautions: Only limited access to the laboratory is allowed..

  • What is biosafety level 2 used for?

    BSL-2 precautions are suitable for work involving agents that pose moderate hazards to personnel and the environment.
    They are appropriate when work is done with any human-derived blood, body fluids, tissues, or primary human cell lines where the presence of an infectious agent may be unknown..

  • What is the difference between biosafety level 2 and 3?

    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..

Virus that causes COVID-19

Severe acute respiratory syndrome coronavirus 2 (SARS‑CoV‑2) is a strain of coronavirus that causes COVID-19, the respiratory illness responsible for the COVID-19 pandemic.
The virus previously had the provisional name 2019 novel coronavirus (2019-nCoV), and has also been called human coronavirus 2019.
First identified in the city of Wuhan, Hubei, China, the World Health Organization designated the outbreak a public health emergency of international concern from January 30, 2020, to May 5, 2023.
SARS‑CoV‑2 is a positive-sense single-stranded RNA virus that is contagious in humans.
