According to The Health Resources and Services Administration (HRSA) of the U.S. Department of Health and Human Services (HHS), telehealth is the use of electronic information and telecommunications technologies to support and encourage long-distance clinical health care, patient and professional health-related education, and public health and health administration. Techniques for telehealth include web conferencing, the internet, store- and-forward imaging, streaming media, and landline and wireless communications.
Telehealth services may be provided, for example, through audio, text messaging, or video communication technology, including video conferencing software.
