Epidemiologists study the distribution and determinants of health-related outbreaks. They use probability, statistics, and other scientific research methods to find specific factors that lead to threatening events or diseases in certain populations. They also use investigative methods to help control the spread of disease. To learn more about the difference between epidemiology and public health, read on! Listed below are some important differences between epidemiology and public health.
Epidemiology studies the distribution, incidence, and patterns of diseases and their impact over time. This helps us understand emerging problems and evaluate the effectiveness of control measures. However, the methods and standards of diagnosis are subject to change, so conclusions drawn from time trends must be cautious. Nevertheless, epidemiology can help identify emerging problems, such as tobacco use, and make informed decisions on the best course of action for a particular community.
In epidemiology, diseases are evaluated in relation to a group of people, known as the population at risk. In other words, the population at risk represents the group of people who would be considered a case if they had the disease. For example, a general practitioner may track consultations for deafness based on a geographic area. But if the patient moved to another location, they would no longer consult a general practitioner.
Public health and epidemiology are complementary fields. Public health focuses on disease prevention, and epidemiology helps determine the causes and prevention of disease and disorder. Both disciplines use statistical methods to study diseases and their causes. The two fields complement one another and each provides valuable insights into human health and public policy. In addition to assessing disease causes, epidemiology is also useful for predicting the spread of illness and identifying preventive measures.
