A New Legislative Framework Public health focuses on the determinants of health rather than the treatment of illness and disability.
Public health is involved in health protection and promotion from a population-based perspective.
This means that it seeks measures that do the most good for the most people. Chronic disease prevention, including heart disease, cancer and prevention of injuries. Infectious disease control, including AIDS and sexually transmitted diseases, vaccine preventable diseases and the control of outbreaks of infectious diseases. Family health, including child health, nutrition, and sexual and reproductive health. By focusing on prevention and promotion, the public health system reduces the expensive health and disability costs associated with medical treatment, chronic disability and lost productivity.
