Several digital tools are pivotal in epidemiology, including: 1. Geographic Information Systems (GIS): Used to map disease spread and identify hotspots. 2. Mobile Health Applications (mHealth): Facilitate real-time reporting and monitoring of health data from individuals. 3. Big Data Analytics: Helps in analyzing large datasets to identify patterns and predict outbreaks. 4. Electronic Health Records (EHRs): Provide comprehensive patient data that can be used for epidemiological studies. 5. Wearable Devices: Collect continuous health data, offering insights into population health trends.
