What Methods are Used to Collect Data in Epidemiology?
Data collection in epidemiology can be done through various methods including:
- Surveys and Questionnaires: These tools gather self-reported data on health behaviors, exposures, and outcomes. - Medical Records: Electronic health records offer comprehensive data on patient histories and clinical outcomes. - Registries: Disease registries provide systematic data on specific conditions, aiding in monitoring trends and evaluating interventions. - Laboratory Tests: Biological samples help in identifying pathogen prevalence and genetic markers. - Environmental Monitoring: Data on environmental exposures, such as air quality and water contamination, are critical for studying their health impacts.
