What is a pathogenic microorganism present in human blood or OPIM called?

A pathogenic microorganism that is present in human blood or other potentially infectious materials (OPIM) is termed a bloodborne pathogen. This classification is critical for understanding the transmission and risks associated with certain diseases. Bloodborne pathogens, such as hepatitis B virus (HBV) and human immunodeficiency virus (HIV), can be transmitted through contact with infected blood or body fluids that can carry these pathogens.

The understanding of bloodborne pathogens is significant in various fields, particularly in healthcare and mortuary science, where there's an increased risk of exposure during the handling of biological materials. Knowledge of how to manage and control these risks is vital for the safety of workers and the public.

Other classifications, such as airborne, foodborne, and waterborne pathogens, refer to different modes of transmission and environmental sources of infection. Airborne pathogens are transmitted through respiratory droplets in the air, foodborne pathogens are spread via contaminated food or beverages, and waterborne pathogens are found in contaminated water sources. Each of these has distinct prevention strategies and is not applicable to microorganisms found in blood and OPIM.
