Telemedicine involves the use of electronic communication and information technologies to provide clinical health care at a distance. It allows health care professionals to evaluate, diagnose and treat patients remotely by transmitting medical information such as images, live videos and data. Telemedicine provides benefits such as improved access to care, lower costs, and better education of professionals and patients. However, it also presents some risks if private medical information is hacked or if it replaces in-person relationships between providers and patients.
