Descriptive Epidemiology Questions
Descriptive Epidemiology Questions
Questions that aim to describe the characteristics of a disease or condition in a population, including who is sick, where they live, and when they became sick. Focus on the 'what,' 'who,' 'where,' and 'when' of disease.
Analytic Epidemiology Questions
Analytic Epidemiology Questions
Questions that explore the causes or reasons behind a disease or condition, focusing on 'why' and 'how' the disease occurred. Aim to identify risk factors and understand the underlying mechanisms.
Experimental Epidemiology Questions
Experimental Epidemiology Questions
Questions that investigate potential intervention strategies to prevent or treat disease, asking 'how can they be made well?' and exploring the effectiveness of different interventions. Focus on finding solutions.

Study Notes
Epidemiologic Questions
- Epidemiologic questions aim to identify the presence of excess disease/conditions.
- Key questions include: Who is sick? (Person) Where do they live? (Place) When did they become sick? (Time)
- Descriptive questions focus on characterizing the health issue.
- Analytic questions delve deeper into the causes and mechanisms of the disease.
- Experimental questions explore potential interventions and treatments.
History of Epidemiology
- Hippocrates: First to link disease to observable environmental factors, like water, air, and personal habits, rather than supernatural causes.
- John Graunt: Developed a quantitative approach to mortality, noting sex and infant mortality rates, creating early life tables and numerical accounts of diseases, such as the plague.
- Edward Jenner: Introduced vaccination through the use of cowpox material.
- John Snow: Determined cholera transmission through contaminated water sources (specifically, a water pump).
Key Epidemiologic Terms
- Latent Carrier Status: Individuals carrying a disease-causing organism without showing symptoms or signs of illness, yet capable of spreading the disease.
- Morbidity: The state of having an illness or condition, which can be acute or chronic (e.g., diabetes, pneumonia, coronary disease). Morbidity can be measured using incidence or prevalence.
- Attack Rate: Proportion of exposed individuals who develop a disease. Calculated as (Number of people developing disease / Total number of people exposed) x 100%.
- Annual Mortality Rate: The number of deaths from all causes in a year per 100,000 people in mid-year.
- Case Fatality Rate: The proportion of individuals with a disease who die from it, calculated as (Number of deaths from the disease / Number of people with the disease) x 100%.
