What term describes infectious microorganisms found in human blood that can cause diseases?

The term that describes infectious microorganisms found in human blood that can cause diseases is "Blood-borne Pathogens." These are microorganisms such as viruses, bacteria, and other pathogens that are transmitted through direct contact with infected blood or other potentially infectious materials. Examples of blood-borne pathogens include the Human Immunodeficiency Virus (HIV), Hepatitis B virus (HBV), and Hepatitis C virus (HCV).

Understanding this term is crucial as it provides insight into the routes of transmission and the necessary precautions required to prevent infection in healthcare settings. Blood-borne pathogens require specific infection control practices, such as the use of personal protective equipment (PPE) and proper disposal of sharps and infectious waste, to minimize the risk of exposure and protect both healthcare workers and patients.

The other terms refer to different modes of transmission. Vector pathogens are typically spread by vectors such as insects, airborne pathogens are transmitted through respiratory droplets, and waterborne pathogens are spread through contaminated water. Each of these categories encompasses distinct types of infections and routes of exposure, making it important to accurately use the terminology associated with them.
