A biological hazard can also be defined as a “bio-hazard”. More specifically it is a by-product from an organism that can cause serious harm to human beings, for example, viruses, toxins and medical wastes.
The Center for Disease Control and Prevention in the United States has divided bio-hazards into four basic levels. A level 1 bio-hazard poses the least risk while a level four poses the greatest.
Present below are a list of the different types of biological hazards:

Present below are a list of the different types of biological hazards:
- Bio-hazard Level 1: This hazard level consists mainly of bacteria and other microorganisms like Bacillus subtilis, canine hepatitis, Escherichia coli etc. The precautions that need to be taken at this level are washing one's hands with anti-bacterial soap and other disinfectants.
- Bio-hazard Level 2: This level of hazard consists of those forms of bacteria and viruses that cause only mild disease as Lyme disease, salmonella, mumps, hepatitis A, B, and C, influenza A, measles, scrapie and dengue fever.
- Bio-hazard Level 3: At this level, the microorganisms involved cause smallpox, SARS, tuberculosis, typhus, Rift Valley fever, yellow fever and malaria. Fortunately, even at this stage there are vaccines available.
- Bio-hazard Level 4: This final stage consists of those forms of bacteria and viruses that can cause some fatal diseases in human beings, such as, H5N1, Lassa fever and even Crimean-Congo hemorrhagic fever.
