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.
