Epidemiologists identify health trends through various methods:
1. Data Collection: They gather data from multiple sources such as health surveys, hospital records, and surveillance systems. 2. Statistical Analysis: They use statistical tools to analyze the collected data to identify patterns and trends. 3. Field Investigations: In some cases, epidemiologists conduct field investigations to collect primary data and understand the context of health events. 4. Surveillance Systems: Continuous monitoring systems help in identifying emerging health threats and trends.
