Blood and body fluid precautions are recommendations designed to prevent the transmission of HIV, hepatitis B virus (HBV), hepatitis C virus (HCV), and other diseases while giving first aid or other health care that includes contact with body fluids or blood. These precautions treat all blood and body fluids as potentially infectious for diseases that are transmitted in the blood. The organisms spreading these diseases are called blood-borne pathogens.
Blood and body fluid precautions apply to blood and other body fluids that contain visible traces of blood, semen, and vaginal fluids. They also apply to tissues and other body fluids, such as from around the brain or spinal cord (cerebrospinal fluid), around a joint space (synovial fluid), in the lungs (pleural fluid), in the lining of the belly and pelvis (peritoneal fluid), around the heart (pericardial fluid), and amniotic fluid that surrounds a fetus.
