2 Biological Agents - definition: A micro-organism (including those which have been genetically modified), a cell culture, and a human endoparasite which may be able to provoke any infection, allergy or toxicity...
3 Biological Agents - definition ctd.: …classified into 4 risk groups according to their level of risk of infectionGroup 1: Unlikely to cause human disease.Group 2: Can cause human disease and might be a hazard to employees but unlikely to spread to the community.
4 Group 3: Can cause severe human disease and presents a serious hazard to employees and may present a risk of spreading to the community (usually effective prophylaxis or treatment).
5 Group 4 : Which causes severe human disease and is a serious hazard to employees and may present a high risk of spreading to the community - usually NO effective prophylaxis or treatment).
