What role does mobile health (mHealth) play in epidemiology?

Mobile health (mHealth) involves the use of mobile devices to collect health data, deliver healthcare information, and monitor patient health. In epidemiology, mHealth tools are used for real-time surveillance, data collection, and dissemination of health information. Mobile apps can track symptoms, gather data from remote areas, and provide instant updates on disease outbreaks. This enhances the ability to respond quickly and efficiently to public health emergencies.
