Fighting against the COVID-19 pandemic caused by the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) virus is one of the most critical challenges facing the global health system today. The possibility to identify the group of persons in the cohort of people under 50 years old, who are sensitive to the Coronavirus Disease-19 (COVID-19) disease by non-invasive methods, is a very perspective approach for estimating the epidemiological state of the human population. The study aimed to identify the features of people’s faces with COVID-19 that the most correlate with disease severity could serve as one of these approaches. For this aim, 525 photos of patients’ faces with different outcomes of COVID-19 disease were analyzed using the Dlib face recognition convolutional neural network pre-trained for face recognition. Face descriptor vectors were obtained using the convolutional neural network. Facial features were found that predict a person’s sensitivity to the SARS- CoV-2 virus (disease severity), and the contribution of each of the features to the risk of developing a severe form of COVID in a person was found. The accuracy of the binary classification of the individual severity of the COVID-19 course using the K-Nearest Neighbor’s (KNN) algorithm on the test dataset was accuracy-84%, Area under the Curve (AUC)-0.90.
