What are blood borne pathogens?

Blood borne pathogens are infectious substances present in the blood that can lead to diseases and infections in individuals who come into contact with infected blood or bodily fluids. These pathogens include a variety of microorganisms, such as viruses and bacteria, that can be transmitted from one person to another through blood contact. Common examples of blood borne pathogens include the Human Immunodeficiency Virus (HIV), Hepatitis B, and Hepatitis C. Preventing the spread of these pathogens is crucial in medical and aesthetic practices, as exposure can have serious health implications.

The other choices do not accurately define blood borne pathogens. The reference to liquid substances that improve hydration does not relate to infectious agents. The mention of viruses transmitted through air refers to airborne pathogens, which are different from blood borne pathogens. Lastly, while some bacteria can be treated with antibiotics, blood borne pathogens specifically highlight infections transmitted through blood rather than just any bacterial infection. Hence, the choice that defines blood borne pathogens as infectious substances in the blood is the correct and most relevant option.
