Berbekov Kabardino-Balkar State University18122021411612108042022Copyright © 2021,2021The analysis of 55 medical records of patients with a diagnosis of new coronavirus infection was carried out. The examination included clinical and biochemical studies, coagulograms, determination of SARS-CoV-2 RNA by PCR, as well as IgM and IgG antibodies to the nucleocapsid protein of SARS-CoV-2 beta-coronavirus by ELISA. In the clinical picture, along with the intoxication syndrome, the manifestations of gastroenterocolitis and skin rashes are significant. Depending on the severity, erythropenia, leukopenia, thrombocytopenia and an increase in the rate of erythrocyte sedimentation are detected, which has significant differences in comparison. The study identified the clinical masks COVID-19 intestinal (23.6% of patients) and cutaneous (5.5% of patients); it was shown that the blood oxygen level is a marker of the severity of coronavirus infection, has a directly proportional relationship with the severity of the course of coronavirus infection in the groups with moderate and severe course. According to the data obtained, the most accurate and objective method of diagnosing pneumonia is chest computed tomography, while chest radiography is informative in the case of lung tissue damage of 25%. Whereas in the early stages of the disease, before the formation of pneumonia, the PCR test is informative.public healthnew coronavirus infectionclinical masksобщественное здоровьеновая коронавирусная инфекцияклинические маски1.Coronaviridae Study Group of the International Committee on Taxonomy of Viruses.
