Coronavirus infection caused by a new strain of SARS-CoV-2 virus contributed to an increase in the number of infectious patients. The Ministry of Health of the Russian Federation and Rospotrebnadzor took over the organization of work to combat the pandemic. In Moscow, medical and preventive events were organized by the Government of the capital and the Department of Health of the city. As soon as possible, it was decided to reassign medical institutions to infectious hospitals for the treatment of patients with COVID-19 or with suspicion of it. “Maternity hospital No. 8” – the branch of State Clinical Hospital named after V. P. Demikhov was redesigned as a hospital on March 13, 2020. The decision was due to the presence of isolated boxes and an intensive care unit in the institution. The task was solved in one day: the first patients with coronavirus infection were admitted to the hospital for medical care at 17:00 on March 13, 2020.
