What are the Common Methods of Data Collection in Epidemiology?
Epidemiologists use various methods to collect data, which can influence the frequency of collection:
Surveys: These can be administered once or multiple times, depending on the study needs. Administrative Data: Often collected continuously or at regular intervals (e.g., hospital records). Syndromic Surveillance: Usually involves real-time or near-real-time data collection. Cohort Studies: Require periodic data collection over long periods.
