Study Notes

Incidence and Prevalence

  • Incidence measures new cases of a disease or condition over a specific time period
  • Prevalence measures existing cases of a disease or condition at a specific point in time
  • Incidence is not affected by duration, whereas prevalence is

Study Types

  • Case-control study: compares a group with a disease (cases) to a group without the disease (controls)
  • Cross-sectional study: examines a population at a single point in time to identify associations between variables
  • Cohort study: follows a group of people over time to examine the development of a disease or condition

Screening and Diagnosis

  • Specificity of a screening test refers to its ability to detect true negatives (those without the disease)
  • Sensitivity of a screening test refers to its ability to detect true positives (those with the disease)

Disease Transmission

  • Cyclical transmission: a pathogen requires an alternate host or vector to complete its life cycle
  • Cyclo-developmental transmission: a pathogen undergoes developmental changes in a vector or intermediate host

Epidemiology
