Surveillance Systems Epidemiologists use surveillance systems to collect data on disease incidence and prevalence. These systems can be passive, relying on reports from healthcare providers, or active, involving proactive data collection.
Outbreak Investigations During an outbreak, epidemiologists conduct investigations to identify the source, mode of transmission, and population at risk. This involves fieldwork, laboratory testing, and data analysis.
Mathematical Modeling Mathematical models help predict the course of an outbreak and evaluate control measures. Models can incorporate various factors, including transmission rates, population mobility, and intervention strategies.
