An Introduction to Public Health and Epidemiology
Many people will not identify their activities as public health. What links these and similar activities together is improving the health of populations or communities. Such a broad range of activities illustrates that the factors which influence health are complex and wide-ranging. Any Attempt to understand and change them must involve many disciplines, and the study of public health draws on the expertise of people from a variety of backgrounds. Statistics, psychology, sociology, microbiology, politics and management are some of the specialities which contribute to the study of the distribution and determinants of health-related states and the application of this study to the control of health problems.
