Based on the assessment of factors that contribute to a new coronavirus infection, the risk of complications, mortality, and lethality from it in the Armed Forces of the Russian Federation were analyzed. A detailed timeline of the development of the coronavirus pandemic in the Russian Federation has been demonstrated, showing indicators of peak and overall morbidity and mortality and prevailing strains of a new coronavirus infection, depending on the waves of the pandemic. The study evaluated the features of the course of a new coronavirus infection in the Eurasian region using data from the international register Analysis of the dynamics of comorbid diseases in patients infected with severe acute respiratory syndrome-2 coronavirus. Modern ideas about the main pathogenetic mechanisms of involvement of the circulatory system, which underlie the development of a severe course, mortality, and lethal outcomes, are outlined. The study also presented the concept of metabolic and hemodynamic insufficiency, which justifies the inability of the desynchronized circulatory system and systems of vascular homeostasis and hemostasis to restore the previous level of functioning after a new coronavirus infection. The possibilities of carrying out differentiated anti-epidemiological measures, including the use of information technologies, aimed at reducing the spread of a new coronavirus infection, were evaluated. The mortality and mortality from a new coronavirus infection in the Armed Forces of the Russian Federation, including the effect of a new coronavirus infection on an increase in the incidence of non-communicable diseases in military personnel of different age groups, were presented. The study also considered issues of the need to introduce a rehabilitation strategy to correct conditions that occur after a new coronavirus infection, reduce the risk of subsequent mortality and lethality, and reduce it in the long term.

Against the background of the global spread of the new SARS-CoV-2 coronavirus, the prevention of infections with airborne mechanisms of transmission has become a priority in the Armed Forces. The development of effective COVID-19 prevention measures requires consideration of the peculiarities of military service and everyday life due to the inability of organized military collectives to comply with the requirements of the lockdown regime introduced at the peak of morbidity by the civilian health system. The patterns of incidence of COVID-19 in military personnel of the Western Military District in organized military collectives were studied in relation to the conditions of training and combat activities and the characteristics of military service. It was found that the dynamics of the incidence of COVID-19 among military personnel of the Western Military District in 20202021 exhibited a wave-like character and included four epidemic rises that coincided with epidemic waves among the civilian population. At the same time, from April to December 2020, the morbidity rate in military personnel was significantly higher than that in the general population, and from January to December 2021 against the background of mass vaccination of military personnel against COVID-19, the incidence rate in military personnel decreased by 50% relative to that in the general population. The effectiveness of anti-epidemic measures has increased significantly in recent months. The average number of patients in the epidemic outbreak decreased by 46.3%, the average duration of the outbreak decreased by 12.4%, and the proportion of group morbidity in the structure of the overall incidence of COVID-19 decreased by 19.8%. It is shown that the incidence of COVID-19 in various types of military collectives depends on the conditions of military service and the specifics of daily activities. The highest epidemiological significance of COVID-19 was detected in military units of constant readiness, as well as in medical and military educational organizations.
