“The study of the distribution and determinants of health and disease in human populations to enable health services to be planned rationally, disease surveillance to be carried out, and preventive and control programs to be implemented and evaluated.” that increase a person’s risk for a disease.
Basic concepts and tools. Epidemiology is based on two fundamental assumptions. First, the occurrence of disease is not random (i.e., various factors influence the likelihood of developing disease). Second, the study of populations enables the identification of the causes and preventive factors associated with disease.
Secondly, what is the definition of Centers for Disease Control and Prevention? The Centers for Disease Control and Prevention (CDC) is a federal agency that conducts and supports health promotion, prevention and preparedness activities in the United States, with the goal of improving overall public health.

Uses of Epidemiology Count health-related events. Describe the distribution of health-related events in the population. Describe clinical patterns. Identify risk factors for developing diseases. Identify causes or determinants of disease. Identify control and/or preventive measures.
What are the three components of epidemiology?
The epidemiologic triangle is made up of three parts: agent, host and environment. Agent. The agent is the microorganism that actually causes the disease in question. Host. The agent infects the host, which is the organism that carries the disease. Environment. HIV.
Why is epidemiology important?
Epidemiology is the study of disease in populations. Epidemiological methods are used for disease surveillance to identify which hazards are the most important. Epidemiological studies are also used to identify risk factors which may represent critical control points in the food production system.
What is epidemiology example?
Epidemiology. Major areas of epidemiological study include disease causation, transmission, outbreak investigation, disease surveillance, environmental epidemiology, forensic epidemiology, occupational epidemiology, screening, biomonitoring, and comparisons of treatment effects such as in clinical trials.
What are the aims of epidemiology?
The principal aim of epidemiology is to identify factors related to the occurrence of disease. Identification of these factors both causal ( causation) and risk factors, enable developing a rational basis for prevention ( epidemiology, prevention).
