Have you ever thought that it will not be necessary to go to the hospital to consult a doctor now? With just a mobile, laptop, or app, you could talk to your doctor from home. Yes, this is telemedicine, in which the facility of treatment comes to you.
Telemedicine means real-time communication between the healthcare provider and patient. It would be a video call, chat, or audio call. It includes everything from diagnosis, consultation, and monitoring for non-emergency problems. But it does not mean it replaces face-to-face consultation.
