Study Notes

Epidemiological Measures

Prevalence measures the total number of cases of a disease or condition in a population at a specific point in time or over a specific period.

Population Types

Fixed/Closed population: A population in which membership is based on an event (e.g., birth) and is permanent.
Dynamic/Open population: A population in which membership is based on a condition (e.g., residency) and is transitory.

Disease Measurement

Prevalence measures the total disease burden in a population, including new and existing cases.
Incidence measures the number of new cases of a disease or condition that occur in a population over a specific period.

Population Membership

Fixed/Closed population membership is based on an event and is permanent, such as being part of a birth cohort.
Dynamic/Open population membership is based on a condition and is transitory, such as being a resident of a particular city.
