Health Promotion and Disease Prevention - Prevention is the key to success in public health. Health promotion and education programs are designed to inform individuals about positive ways in which they can preserve or restore their own health-smoking cessation, moderation in alcohol consumption, proper diet and exercise, wearing seat belts,, etc. Disease intervention programs work to stop the transmission of diseases from a carrier to others by immunizing people against certain diseases, treating new cases as they occur and isolating carriers if necessary, and finding and testing people who have been in contact with an infected patient to administer the proper treatment before the disease becomes contagious. Health Treatment - Health care of the sick and disabled is a role that public health undertakes when individuals are too poor or otherwise lack access to health care services.
