Primary prevention aims to prevent disease or injury before it ever occurs. This is done by preventing exposures to hazards that cause disease or injury, altering unhealthy or unsafe behaviors that can lead to disease or injury, and increasing resistance to disease or injury should exposure occur. Use of masks, gloves, and gowns when cleaning up a patient's blood is an example of primary prevention as it prevents exposure to potentially infectious materials.
