Public Health
An aspect of Health Services concerned with threats to the overall health of the population of a community based on population health analysis. It generally includes infectious disease surveillance and infectious disease control and promotion of healthy behaviours (health promotion)among members of the community. Both vaccination programs and free distribution of condoms are Public Health measures. The WHO sets standards and provided global surveillance, but national bodies such as the Centers for Disease Control and Prevention in Atlanta, Georgia, U.S.A. and their local affiliated Medical Officer of Health are usually the lead in responding to Public Health threats.
