Biosafety Chapter 1. Classification of infective microorganisms by risk group (WHO Risk Groups 1, 2, 3 and 4) for laboratory work
dRisk Group 1(no or low individual and community risk): A microorganism that is unlikely to cause human or animal disease Risk Group 2(moderate individual risk, low community risk): A pathogen that can cause human or animal disease but is unlikely to be a serious hazard to laboratory workers, the community, livestock or the environment. Laboratory exposures may cause serious infection, but effective treatment and preventive measures are available and the risk of spread of infection is limited
❑Risk Group 1 (no or low individual and community risk): A microorganism that is unlikely to cause human or animal disease. ❑Risk Group 2 (moderate individual risk, low community risk): A pathogen that can cause human or animal disease but is unlikely to be a serious hazard to laboratory workers, the community, livestock or the environment. Laboratory exposures may cause serious infection, but effective treatment and preventive measures are available and the risk of spread of infection is limited
dRisk Group 3(high individual risk, low community risk ): A pathogen that usually causes serious human or animal disease but does not ordinarily spread from one infected individual to another, effective treatment and preventive measures are available. Risk Group 4(high individual and community risk ): A pathogen that usually causes serious human or animal disease and that can be readily transmitted from one individual to another, directly or indirectly Effective treatment and preventive measures are not usually available
❑Risk Group 3 (high individual risk, low community risk): A pathogen that usually causes serious human or animal disease but does not ordinarily spread from one infected individual to another. Effective treatment and preventive measures are available. ❑Risk Group 4 (high individual and community risk): A pathogen that usually causes serious human or animal disease and that can be readily transmitted from one individual to another, directly or indirectly. Effective treatment and preventive measures are not usually available
lAboratory facilities are designated as basic Biosafety Level 1, basic Biosafety Level 2, containment- Biosafety Level 3, and maximum containment- Biosafety Level 4 bIosafety level designations are based on a composite of the design features, construction containment facilities equipment, practices and operational procedures required for working with agents from the various risk groups
