Biostatistical concepts and tools are needed for summarizing and analysing data. This is especially true in epidemiological research, which requires the use of samples to make inferences about entire populations. This content will describe basic concepts and methods, and how to summarize data. Although calculations can be complex, the concepts underlying statistical tests are often […]

A major focus of epidemiology is informing efforts to prevent and control disease and promote health. To do this, we need to know the causes of disease or injury and the ways in which these causes can be modified. This content describes the epidemiological approach to causation.   Proceed through the content in chronological order,

Chronic noncommunicable diseases are major public health challenges in most countries. In addition to effective treatment, much is already known  about these disease, including the fact that primary prevention is the best strategy to control these modern epidemics. Targeting high-risk individuals with secondary and tertiary prevention can also reduce the burden of chronic disease.  

New communicable diseases regularly emerge, and old ones re-emerge, making them a continuing threat to public health throughout the world. Epidemiological methods make possible effective approaches to the critical responsibilities of surveillance, detection, control, and prevention of communicable disease outbreaks.   Proceed through the content in chronological order, and click the “Complete” button at the

Clinical epidemiology is the application of epidemiological principles and methods to the practice of clinical medicine. It usually involves a study conducted in a clinical setting, most often by clinicians, with patients as the subjects of study. The aim of clinical epidemiology is to aid decision-making about identified cases of disease.   Proceed through the

Most diseases are either caused or influenced by environmental factors. Understanding these is essential to design effective prevention programs. Environmental epidemiology provides a scientific basis for studying and interpreting the relationships between the environment and population health. Occupational epidemiology deals specifically with environmental factors in the workplace.   Proceed through the content in chronological order,

The full value of epidemiology is only realized when it is translated into health policy and the subsequent planning and implementation of disease or injury prevention and control programs. Health policy is essentially a set of decisions about strategic goals for health, and the means for achieving these goals.   Proceed through the content in
