10 Best Free Online Epidemiology courses

In this article, you will find a list of the 10 best free online epidemiology courses and where you can attend these courses. You will also find the meaning of epidemiology, its studies, the benefits of studying epidemiology courses online, and other important information that regards epidemiology.

In the Mid 1800s, an anesthesiologist named John Snow conducted a series of investigations in London that warrant his being considered the “father of epidemiology”. Before the microscope was developed, he had already conducted studies of cholera outbreaks to discover the cause of the disease and to prevent its reoccurrence.

following these several investigations from John Snow, people began to show interest in studying epidemiology. Today, epidemiology is seen as a very vital course and it is also regarded as the cornerstone of public health.

There are several courses studied under epidemiology currently, but we have provided for you a list of the best 10 free online Epidemiology courses that will interest you.

Most free online epidemiology courses are OpenCourseWare (OCW) classes, which means they were offered on campus but are now available online for free.

before we proceed with listing these free online courses, let’s take a look at the definition of Epidemiology and its studies.

What is Epidemiology?

The word epidemiology comes from the Greek words epi, meaning on or upon, demos, meaning people, and logos, meaning the study of. In other words, the word epidemiology has its roots in the study of what befalls a population.

Epidemiology is the branch of medical science that investigates all the factors that determine the presence or absence of diseases and disorders. It is also the study of how often diseases occur in different groups of people and why.

Epidemiological research helps us to understand how many people have a disease or disorder, if those numbers are changing, and how the disorder affects our society and our economy.

Information obtained from epidemiology is used to plan and evaluate strategies to prevent illness and as a guide to the management of patients in whom the disease has already developed.

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.

Having understood the meaning of epidemiology, let’s take a quick look at its studies before we proceed with the list of the best free online epidemiology courses.

Types of Epidemiological studies

Epidemiological investigations can be grouped into four broad categories: Observational epidemiology, experimental epidemiology 

Experimental studies

Experimental studies are ones where the epidemiologist can control and manipulate different variables throughout the experiment. It usually involves a placebo treatment/group. This type of study is used when epidemiologists are trying to determine the cause of a health issue/disease or when evaluating the effectiveness of a cure or interventions.

Three types of experimental epidemiology are:

  • randomized control trial (RCT) – uses healthy individuals as units of study, mostly for assessing preventive agents like vaccines
  • field trial – uses healthy individuals as units of study, mostly for assessing preventive agents like vaccines
  • community trial – uses communities as units of study for assessing community-based interventions.

Observational Studies

Observational studies include descriptive and analytical studies; descriptive studies investigate epidemiological cases with regards to time, place, and person while analytical study investigates hypotheses regarding relationships between health issues and risk factors.

While descriptive studies time, place, and person, answer questions of when, who, and where, analytical studies try to answer the question of how a population is affected by a disease and why they are affected.

In analytic observational studies, the researcher simply measures the exposure or treatments of the groups. Analytical observational studies include case-control studies, cohort studies, and some population (cross-sectional) studies. These studies all include matched groups of subjects and assess associations between exposures and outcomes.

Observational studies investigate and record exposures (such as interventions or risk factors) and observe outcomes (such as disease) as they occur. Such studies may be purely descriptive or more analytical.

Validity and Bias in Epidemiology

Epidemiological studies can provide valuable insights into the frequency of a disease, its potential causes, and the effectiveness of available treatments. Selecting an appropriate study design can take students a long way when trying to answer such a question. However, this is by no means enough. A study can yield biased results for many different reasons.

This course offers an introduction to some of these factors and provides guidance on how to deal with bias in epidemiological research. In this course, students will learn about the main types of bias and what effect they might have on your study findings.
