The word 'epidemiological' is used to describe the study of how diseases spread and how they affect a group of people or a community. It is often used in the context of health and public health, and is used to describe how diseases and health issues affect people in different areas or populations. For example, epidemiological studies can help us understand why a particular disease is more common in one group of people compared to another, or how to prevent the spread of a disease in a community.
