    Study Notes

    Epidemiology Basics

    • The term that refers to the number of people to whom something happened, such as getting sick or dying is called the numerator.

    Epidemiologic Triangle

    • The Epidemiologic Triangle examines three characteristics to study the cause(s) for disease: Agent, Host, and Environment.
    • Agent refers to biological agents such as viruses and bacteria that contribute to the occurrence of diseases.
    • Host refers to humans or animals that are affected by the disease.
    • Environment refers to the external factors such as air, water, and soil that can contribute to the occurrence of diseases.

    Case Reports

    • Case reports describe unusual features of a disease or an individual, providing valuable insights into rare or unique cases.

    Epidemiological Concepts

    • Biological agents are not always necessary causes for infectious diseases, they may be contributory factors.
    • The environment plays a crucial role in the occurrence of diseases, and its significance should not be overlooked.
    • The denominator represents the total population at risk, and is used in conjunction with the numerator to assess disease occurrence.
    • Host is not limited to humans in epidemiology; it can refer to animals or any living being affected by the disease.
