The article presents the results of the analysis of clinical features of gastroenterological manifestations of a new coronavirus infection (COVID-19) caused by the pathogen SARS-CoV-2. Taking into account the stage-by-stage system assessment of the experience of treating 1,180 patients in a multi-specialty hospital transformed into an infectious hospital, the most characteristic clinical manifestations of digestive damage by SARS-CoV-2 coronavirus are described.
