Real-time Data Collection: Telehealth enables the collection of real-time health data, which can be crucial for tracking disease outbreaks and monitoring public health trends. Improved Access: Telehealth can reach populations in remote or underserved areas, ensuring that epidemiological studies include a more diverse sample. Cost-Effectiveness: By reducing the need for physical infrastructure and travel, telehealth can lower the costs associated with conducting large-scale epidemiological studies.
