Disease prevention is "a branch of medicine that focuses on the prevention of diseases and in communities." This term may also refer to other plant and animal species.
There are three levels of disease prevention: Primary, Secondary and Tertiary. Primary prevention refers to the prevention of diseases before they start. For example, pasteurizing milk eliminates any bacteria that can cause illness ,and measles immunization prevents clinical illness before it starts. Another form of primary prevention occurs when older people with osteoporosis wear hip protectors which absorb the shock of a fall and are able to prevent hip fracture. Behavioral interventions are other examples of primary prevention. These can include preventive dental care, stop smoking programs and regular exercise. Routine physicals checking for genetic abnormalities are another form of primary prevention since abnormal genes that are associated with variuos diseases can often be detected before any disease develops. For example newborn screening for phenylketonuria, a metabolic disease that can be subvereted with a proper diet. There are many ethical problems in routine searching for genetic abnormalities and appropriate approaches need to be developed.
