Barbering Infection Control Practice Test

HIV (Human Immunodeficiency Virus) and Hepatitis B are prime examples of bloodborne pathogens because they are primarily transmitted through blood and other potentially infectious materials. Bloodborne pathogens are microorganisms present in human blood that can cause disease in humans. HIV is known for its role in leading to AIDS (Acquired Immunodeficiency Syndrome), and it can be transmitted through blood, sexual contact, and from mother to child during childbirth or breastfeeding. Hepatitis B is a viral infection that attacks the liver and is also transmitted in similar ways, particularly through contact with infected blood. The other options listed involve pathogens that are typically transmitted through respiratory droplets or other routes—not through blood. The common cold virus and flu virus are respiratory viruses, while strep throat bacteria are normally spread through respiratory secretions. Thus, they do not fall into the category of bloodborne pathogens, making HIV and Hepatitis B the correct choice in this context.
