<p><strong>Materials</strong><strong> and Methods. </strong>The study included epidemiological, statistical, and mathematical research methods with retrospective analysis of COVID-19 morbidity and COVID-19 preventive measures in resuscitation units of a multifield hospital.</p>
<p><strong>Results</strong><strong>.</strong> The results of the study indicated the highest incidence of COVID-19 among medical personnel in the cardiac surgery and neuroresuscitation units with the highest rates among physicians (66.6 and 45.5 %). The determining risk factors for infection with COVID-19 and other pathogens of acute respiratory diseases among medical personnel were the following: admission of patients in urgent condition to the department without examination results; high load for doctors working with patients, determining the excessive use of personal protective equipment (PPE) by two, four times; violation of rules for PPE removal and utilization conditions, improper storage and contamination of clean PPE, low proportion of PPE use in the interepidemic period; procedures associated with formation of aerosol, airtightness failure during mask ventilation in 24 % of patients that led to leakage of aerosol into the environment, insufficient coverage of medical personnel with preventive vaccination against COVID-19 in some units.</p>
<p><strong>Conclusions</strong><strong>.</strong> The high incidence of COVID-19 among medical personnel and workload, violations of PPE usage, and procedures with aerosol formation specific for resuscitation units all these things determine the increased risk of COVID-19 spread by medical staff in resuscitation units.</p>personal protective equipmentresuscitationcovid-19medical personnelсредства индивидуальной защитыреанимацияcovid-19медицинский персонал[Application of masks in COVID-19 conditions.
