ABSTRACT
Telemedicine (TM) is used to treat patients in a remote location by using telecommunication technology. It exchanges the medical information and data from one location to another through advanced technological innovation. During this COVID-19 pandemic, there is a lockdown in almost all countries. TM is beneficial to healthcare to minimize social distance. This review paper briefs about TM and discusses how this technology works for the COVID-19 pandemic and its significant benefits. An extensive search is made on the known research engines of PubMed, SCOPUS, Google Scholar, and ResearchGate using the appropriate keywords to extract meaningful and relevant articles. Ten major applications of TM for COVID-19 are identified and discussed with a brief description of each provided. The major technological processes involved in TM, which create advancement in the medical field, are also discussed. This technology helps avoid visits to the doctor and hospital during the lockdown and provides a suitable treatment option. It collects the medical information and data, which can be helpful for better treatment of the patient. Telemedicine adopts virtualized treatment approaches for the patient. Now patients can receive better quality treatment without leaving their homes during COVID-19 lockdown.
