In this article we analyze the existing big data processing resources that contribute to displaying information in an acceptable form in real time during the COVID-19 coronavirus infection. It is proposed a mobile application using big data analytics, which is able to provide assistance in the conditions of a pandemic to provide remote access for the purpose of online visits to healthcare organizations. The "Big data" results of processing make it possible to quickly get the necessary data as quickly as possible, make it possible to make diagnoses more accurately, check medical data without burdening doctors, and also integrate the results of studies performed on different devices into a common system. The speed of data access and the speed of their processing is an important criterion for the quality of technologies included in Big Data. Access to this application is planned to be carried out through Google Play.
