What are infections spread through blood and bodily fluids called?

Infections that are transmitted through blood and bodily fluids are classified as blood-borne viruses. These types of infections can include well-known examples such as HIV (Human Immunodeficiency Virus) and Hepatitis B and C. The defining characteristic of blood-borne viruses is that they are spread via direct contact with infected bodily fluids, such as blood, semen, or vaginal secretions.

This classification is crucial for understanding the modes of transmission and the necessary precautions that must be taken in healthcare settings and other environments where exposure might occur. Recognizing blood-borne viruses helps in the development of public health strategies and education to prevent their spread, particularly in contexts like blood donation, medical procedures, and sexual health.

Other categories like airborne viruses refer to infections that are spread through the air, waterborne pathogens relate to water contamination, and foodborne illnesses are associated with the consumption of contaminated food, which are distinct from the transmission methods of blood-borne infections.
