Epidemiologists rely on various types of data to conduct their research, including:
Surveillance Data - Continuous, systematic collection, analysis, and interpretation of health-related data. Cohort Studies - Follow a group of people over time to determine how certain factors affect health outcomes. Case-Control Studies - Compare individuals with a disease to those without to identify risk factors. Randomized Controlled Trials - Assess the effectiveness of interventions by randomly assigning subjects to different groups.
