Primary prevention is "specific practices for the prevention of disease or mental disorders in susceptible individuals or populations. these include health promotion, including mental health; protective procedures, such as communicable disease control; and monitoring and regulation of environmental pollutants. Primary prevention is to be distinguished from secondary prevention, which is the prevention of complications or after-effects of a drug or surgical procedure, and tertiary prevention, the amelioration of the after-effects of a disease."
Regarding the opportunity cost of primary prevention of diseases, one analysis concluded, "opportunities for efficient investment in health care programs are roughly equal for prevention and treatment."
