The use of electronic services through a wide range of communication platforms to provide knowledge in order to provide health to populations, in what is known as telehealth. This article shows scientific evidence of the merit of the use of telehealth in the education of health sciences students and in primary care research during the COVID-19 pandemic as central axes for the success of health control programs in the approach to this emerging disease, based on the review of scientific studies in digital format published up to May 2021 that met the inclusion criteria (originality, adequate conclusions and no duplication). The information found is organized into three sections to facilitate reading and understanding, namely: telehealth in the COVID-19 pandemic; preparation in primary care of health sciences students based on telehealth and COVID-19; and research in primary care in times of information and communication technology and the COVID-19 pandemic. Finally, as a product of the analysis, the authors provide conclusions.
