    Study Notes

    Epidemiology and Communicable Diseases

    • Epidemiology is the study of the distribution and determinants of health-related events, diseases, or health-related characteristics among populations.
    • A communicable disease is a disease that can be transmitted from one person to another or from an animal to a person.
    • The epidemiologic triad consists of agent, host, and environment.

    Infectious Disease Model

    • The infectious disease model consists of agent, host, and environment.
    • Agent refers to the infectious substance or organism that causes disease.
    • Host refers to the person or animal that can be infected.
    • Environment refers to the external factors that contribute to the spread of disease.

    Key Terms

    • Vector: an insect or any living carrier that transports an infectious agent from an infected individual to a susceptible individual.
    • Reservoir: a person or animal that affords subsistence or lodgement to an infectious agent under natural conditions.
    • Fomite: the presence of an infectious agent on a body surface, clothes, beddings, or other articles.
    • Portal of entry: the entry and development or multiplication of an infectious agent in the body of humans or animals.
    • Incidence: the number of new cases of an infectious disease in a given time period.
    • Prevalence: the number of cases of an infectious disease at a given time.
    • Habitat: the natural habitat of an infectious agent where it normally lives and multiplies.

    Importance of Studying Communicable Diseases Epidemiology

    • It is important to study communicable diseases epidemiology to understand the causes and distribution of diseases, which can inform public health policy and prevention strategies.

    Miscellaneous

    • Infestation refers to the lodgment, development, and reproduction of arthropods on the surface of the body or in clothing.
    • Infection refers to the entry and development or multiplication of an infectious agent in the body of humans or animals.
    • Infestation can also refer to the lodgment, development, and reproduction of parasitic worms in the gut.
