Role of Digital Health in Modern Epidemiological Surveillance

Abstract

Epidemiological surveillance is one of the basic concepts of the practice of public health that allows gathering health data systematically, analyzing it, interpreting it, and spreading the results to make decisions on the prevention and control of diseases. Although traditional surveillance systems are fundamental, they are usually constrained by slow reporting, sub-par coverage, and reliance on manual data collection systems. The meteoric growth of digital health technologies has altered the situation in epidemiological surveillance by offering the possibility of real-time data collection, analytical capacity, and coverage to a greater population. Electronic health records, mobile health applications, wearable devices, telemedicine platforms, and digital disease surveillance systems represent digital health tools that have brought about new opportunities of detecting outbreaks in time, tracking trends of diseases, and assessing the effectiveness of the intervention to the health of the population. This narrative review delves into how digital health is changing the nature of contemporary epidemiological surveillance, particularly the most important technologies, applications, benefits, and limitations. It is also discussed in the review how ethical, legal, and equity-related issues can be addressed and what the future of incorporating digital health innovations into strong and adaptive surveillance systems can be. The results highlight the importance of the digital health as a way of enhancing epidemiological surveillance mechanisms, bettering the decision-making of the general population, and increasing the global health security under a responsible and inclusive implementation.
