What term describes microorganisms such as viruses or bacteria that are carried in blood and can cause disease?

The term that describes microorganisms such as viruses or bacteria that are carried in blood and can cause disease is "Bloodborne Pathogens." Bloodborne pathogens are specifically defined as infectious microorganisms found in blood that can lead to diseases in humans. These include, but are not limited to, viruses like HIV and Hepatitis B and C.

Understanding this term is critical in the context of health and safety, especially in settings where there may be exposure to blood, such as healthcare and emergency response environments. Recognizing bloodborne pathogens helps in implementing appropriate safety protocols to prevent transmission and protect both workers and patients.

The other terms, while relevant within the broader context of infectious diseases and safety, do not specifically refer to the pathogens carried in blood. For instance, "Infectious Agents" is a broader category that includes any organism capable of causing disease, not limited to those found in blood. "Contagious Diseases" refers to diseases that are easily transmitted from one person to another, but does not specifically denote their presence in blood. "Hazardous Materials" is a regulatory term that encompasses a wide range of substances that pose a risk to health, safety, and property, which is much broader than just bloodborne pathogens.
