Relevance . The pandemic of a new coronavirus infection has become an unprecedented challenge for modern society. It took the entire population of the Earth by surprise, changing the lives of millions of people in the world in record time. Governments of different countries have reacted differently to the pandemic. The list of preventive measures and the timeliness of their adoption differed. Comparing and evaluating the experience of different countries and emergency response systems will help in the future to use best practices and models to combat future biological threats. The aim of the study was to identify and describe the features of the manifestation of the COVID-19 epidemic process in a number of countries, taking into account the ongoing anti-epidemic and preventive measures, and to hypothesize about the main factors that could potentially influence the differences in the manifestation of the COVID-19 epidemic process. Materials and methods . The choice of countries was conditioned by the purpose to compare the manifestations of epidemic process in our country with the great powers and economies of the world - USA and China and countries (Republic of Belarus and Sweden), which did not introduce lockdown and did not follow all WHO recommendations. To achieve this goal, a descriptive research method was used based on open source data, an analysis of relevant Russian and foreign literature was carried out (scientific electronic libraries PubMed and Elibrary; open sources of statistical information: Yandex DataLens Public: Coronavirus: Dashboard, Johns Hopkins University website, United Nations Population Division, World Bank, Global Panel Database on COVID-19 Pandemic Policy (Oxford COVID-19 Government Response Tracker), as well as the website of the World Health Organization (WHO), Our World in Data, Rospotrebnadzor and some media). Conclusion . The lowest incidence rate is observed in China (on average 315.1 per 100 thousand population [95% CI 314.8–315.4]), and the highest is in the USA (9957.7 per 100 thousand population [95% CI 9954.5–9960.9]). In terms of the number of tests conducted, the United States and Russia are in the lead. To date, the highest vaccination coverage and vaccination rate are observed in the PRC and amount to 92.4% and 90.1%, respectively. In general, these indicators do not reach 95% in all countries, which requires improving the quality of immunoprophylaxis measures. Anti-epidemic measures in the studied countries differed in their set, scope and severity of implementation. In China, Russia and the USA were held in full, and in Belarus and Sweden only partially, some of the events were not held at all. Thanks to the rapid creation of effective vaccines in Russia and China, it was possible to delay the onset of pronounced increases in morbidity at a later date, which, in turn, helped to reduce the burden on the healthcare system.

的相关性。新型冠状病毒感染大流行成为现代社会面临的前所未有的挑战。它让地球上的所有人都大吃一惊,在创纪录的时间内改变了世界上数百万人的生活。不同国家的政府对这一流行病的反应不同。预防措施的清单和采取这些措施的及时性各不相同。比较和评估不同国家和应急系统的经验将有助于今后使用最佳做法和模式来应对未来的生物威胁。本研究的目的是识别和描述一些国家的COVID-19流行过程的表现特征,同时考虑到正在进行的防疫和预防措施,并假设可能影响COVID-19流行过程表现差异的主要因素。材料和方法。选择国家的目的是将我国流行病过程的表现与世界上的大国和经济体-美国和中国以及没有实行封锁和没有遵循世卫组织所有建议的国家(白俄罗斯共和国和瑞典)进行比较。为了实现这一目标,采用了基于开源数据的描述性研究方法,对相关的俄罗斯和外国文献进行了分析(科学电子图书馆PubMed和library;公开统计信息来源:Yandex DataLens公开:冠状病毒:仪表盘、约翰霍普金斯大学网站、联合国人口司、世界银行、COVID-19大流行政策全球小组数据库(牛津COVID-19政府应对跟踪器),以及世界卫生组织(WHO)网站、Our World in Data、Rospotrebnadzor和一些媒体)。结论。发病率最低的是中国(平均每10万人315.1例[95% CI 314.8-315.4]),最高的是美国(每10万人9957.7例[95% CI 9954.5-9960.9])。就试验次数而言,美国和俄罗斯处于领先地位。迄今为止,中国的疫苗接种率和疫苗接种率最高,分别达到92.4%和90.1%。总的来说,这些指标在所有国家都没有达到95%,这就需要提高免疫预防措施的质量。所研究的国家的防疫措施在实施的种类、范围和严重程度上各不相同。在中国、俄罗斯和美国举行了全部比赛,在白俄罗斯和瑞典只举行了部分比赛,有些比赛根本没有举行。由于俄罗斯和中国迅速研制出有效的疫苗,有可能将发病率显著上升的发病时间推迟到较晚的日期,这反过来又有助于减轻医疗保健系统的负担。与此同时,尽管COVID-19具有明显的相关性,但对所谓的风险因素(生物、社会和自然)进行全面研究的问题仍然存在。这种病毒现在有一定的可能性永久存在于全球人口中(它将成为一种季节性疾病)。

Relevance . Violation of the regulations on the use of personal protective equipment (PPE) by medical workers when providing medical care to patients with COVID-19 (COVID-19) at their workplaces and in other situations requiring PPE is fraught with serious consequences for the health and life of medical personnel and patients. Aims . To assess the impact of violations in the use of PPE on the incidence of COVID-19 of personnel of medical organizations of various profiles, including when providing medical care to patients with COVID-19. Materials and methods . The study used the method of cross-sectional retrospective simultaneous online questionnaire to assess the effectiveness of preventive measures against the spread of COVID-19, conducted from January to March 2022. The results of an anonymous online survey of various categories of personnel of medical, scientific and educational medical organizations of the Russian Federation providing medical care to patients with COVID-19 (n = 6032 people) were analyzed. Results . The study showed the greatest epidemiological significance in the formation of the risk of SARS-COV-2 infection by the irregular use of masks and gloves in the workplace (when providing medical care). The results of the assessment of the strength of the connection of violations in the use of personal protective equipment with infection with SARS-CoV-2 of the studied groups of personnel are presented. It is shown that the irregular wearing of face masks in the workplace when providing medical care has the most pronounced association with the risk of infection of all the factors studied. It is noted that statistically significantly more often the irregular use of masks and gloves in the workplace was allowed by students and nursing staff. Conclusions . The importance of compliance with the regulations for the use of personal protective equipment by medical workers is shown, not only when providing medical care to patients with COVID-19, but also at home, as well as the impact on the incidence of COVID-19 of the irregularity of the use of PPE by medical personnel in various conditions, including when providing medical care to patients with COVID-19.

Relevance. In 2007, WHO recommended pneumococcal conjugate vaccines (PCV) be included in national immunization schedules for young children. By 2020, 145 countries, including Russia, were using PCV. Aims . To identify vaccines with high epidemiological and immunological efficacy against various forms of pneumococcal infection, including carriage. Conclusions . It has been shown that PCV has high epidemiological and immunological efficacy against various forms of pneumococcal infection, including carriage. It was revealed that the mass use of PCV, leading to the elimination of "vaccine" serotypes, is simultaneously accompanied by the spread of cases of infection due to serotypes not included in vaccines, which significantly reduces the positive effect of vaccination. This requires frequent replacement of serotype polysaccharides in the vaccine in accordance with the serotypes of circulating strains. An alternative to PCV can be vaccines based on pneumolysin, surface pneumococcal proteins, whole – cell and live attenuated, protein-based subunit vaccines, etc. vaccine variants.

Teaching the discipline «Epidemiology» to foreign students is associated with certain difficulties due to both the lack of equivalents in the English language of terms and concepts used in Russia and the historically established difference in approaches to studying the occurrence and spread of diseases in human society. Schematically, in English-language literature and textbooks on epidemiology, the process of the occurrence of diseases is described on the model of the epidemiological triangle, in Russian literature – historically on the model of the epidemic process, the founder of the doctrine of which is L.V. Gromashevsky. The epidemiological triad is represented by the interaction of a human host, agent and environment – the basis of the epidemic process are 3 elements: the source of infection, the transmission mechanism and the susceptible organism. At first glance, the model of the epidemic process and the epidemiological triangle are somewhat similar. However, the model of the epidemic process according to L.V. Gromashevsky more clearly indicates the population level of the phenomenon, and the epidemiological triangle pays more attention /emphasis on the properties of the pathogen and its interaction with the human body (the level of organism) in the external environment. Teaching in the section «General epidemiology of infectious diseases» teaching about the epidemic process for foreign students is advisable to build from universal models such as the epidemiological triad, harmoniously combining the epidemiology of infectious and non-communicable diseases, followed by the separation of these concepts and the introduction of specific terminology adopted in Russia (source of infection, epidemic focus, transmission mechanism, transmission pathways). At the same time, along with non- communicable diseases, the processes of the spread of infections associated with the provision of medical care, sapronoses are most significantly illustrated with the help of an epidemiological triangle.

Relevance . To maximize the success of COVID-19 vaccination, it is necessary to consider the sensitivity of population health not only to these specific exposures, but also to the inherent socioeconomic factors that can modulate the effectiveness of health interventions. Aims . To assess the relationships between infection, mortality and the fatality ratio from COVID-19 in the countries of the world with the proportion of vaccinated in the population, as well as the relationship of the epidemic situation on COVID-19 with the parameters of the well-being of the population based on a cross-sectional study. Materials and methods . Statistical analysis used the data of the portal Our World in Data as of 15/12/2021, as well as UNO data on human development. Results. The frequencies of infection and death were higher the higher the human development index of countries. The inverse correlation of vaccination rates with infection and mortality rates was typical only for countries with very high human development. In the same group of countries, the infection fatality rate was the lowest. Conclusion. The nature of the correlations between the level of vaccination and the parameters of the epidemic situation is not the same for countries with different levels of human development. Apparently, a number of socio-economic factors, including the integral level development of the country and the level of urbanization, can influence the effectiveness of vaccination.

Relevance . It is known that the main trigger for the development of the pandemic was the genomic diversity of viruses. Meanwhile, we did not find any studies on the influence of population susceptibility on the complex process of evolutionary transformations of the SARS-CoV-2 virus and their interdependent variability during the development of the pandemic. Aim . The study of the interdependent variability of two heterogeneous populations interacting in the dynamics of the development of the COVID-19 pandemic - the virus population and the population. Materials and methods . The study was conducted in the city of Perm from 03/01/2021. (Beginning of sequencing of the SARS-CoV-2 virus in the territory) until 01.01.2023. In weekly dynamics, the following were studied: SARS-CoV-2 genomic diversity (molecular genetic study of 2521 samples of biomaterial from patients), seroprevalence of the population (366,804 blood sera were examined for the presence of IgG), morbidity, disease prevalence rate and mortality (according to official statistics). The interpretation of the results was carried out in accordance with the provisions of the theory of self-regulation of parasitic systems by V.D. Belyakov. Results and discussion. An analysis of the genomic diversity of the virus during the pandemic made it possible to distinguish 5 periods. Three periods were characterized by the homogeneity of the pathogen population, when the variants Alpha, Delta and Omicron circulated. Two periods were characterized by the simultaneous circulation of two variants of viruses due to the adaptation of the virus to the changed habitat. Thus, the circulation of the Alpha variant in a population heterogeneous in terms of susceptibility (the proportion of seropositive ones increased to 52%) caused mutational changes in the virus genome with the formation of high transmission properties and high pathogenicity (according to the theory of V.D. Belyakov, the phase of formation of an epidemic variant). The formation of the epidemic variant of the pathogen (Delta genovariant) occurred within 12 weeks, it dominated for more than 6 months, increasing the incidence by 2.8 times, mortality by 17.3 times (epidemic spread phase). The increase in the incidence and large-scale vaccination increased the seroprevalence of the population to 70% or more. The Delta variant begins to adapt to a new habitat with a high proportion of immune organisms, the formation of the Omicron genovariant with high transmission and evasion of the immune response is underway (the phase of formation of the pathogen reservation variant). The pathogen population is heterogeneous; Delta and Omicron circulate simultaneously. Morbidity increases by 2.9 times, RT by 1.3 times, and mortality decreases by 5.1 times. Omicron replaces the Delta genovariant within 5 weeks, mortality decreases, while maintaining the distribution coefficient (reservation phase). Conclusions .

The Delta variant begins to adapt to a new habitat with a high proportion of immune organisms, the formation of the Omicron genovariant with high transmission and evasion of the immune response is underway (the phase of formation of the pathogen reservation variant). The pathogen population is heterogeneous; Delta and Omicron circulate simultaneously. Morbidity increases by 2.9 times, RT by 1.3 times, and mortality decreases by 5.1 times. Omicron replaces the Delta genovariant within 5 weeks, mortality decreases, while maintaining the distribution coefficient (reservation phase). Conclusions .

Relevance . In the Russian Federation, despite the low incidence rate in 2020–2021, there are subjects where the incidence rate of meningococcal infection (MI) exceeds the national average by 2–9 times. MI often becomes fulminant with an extremely rapid development of symptoms up to infectious and toxic shock, which limits the possibility of providing specialized care. Less than 24 hours may pass between the appearance of the first symptoms (nonspecific, similar to ARVI) and the development of shock with a fatal outcome. To date, the most reliable way to protect against meningococcal infection is vaccination. However, the healthcare system until 2022 could use only one domestic vaccine with one serogroup A. Aims . To study the safety, reactogenicity and immunological efficacy of Meningococcal A+C polysaccharide vaccine, manufactured by Microgen, Russia, when used in persons aged 18 to 60 years. Materials and methods . The study included 100 people aged 18–60 years who met the inclusion criteria, the average age of the participants was 31.09 ±1.13 years. All study participants were evenly divided into two groups. The Meningo A+C® vaccine, Sanofi Pasteur, France (hereinafter referred to as MPV2 AC) was used as a comparison. PHA study was carried out using the test system «A set of diagnostic reagents for erythrocyte meningococcal polysaccharide groups A, B, C liquid according to TS 9388-004-68925985-10» manufactured by Bio-Diagnostics LLC, Russia (registration certificate No. FSR 2011/11185 dated 17.10.2011). Results and discussion . The results of the study assessing the reactogenicity and safety of the vaccine: in the first 7 days after vaccination, reactions were registered in 12.0% (95% CI: 5.62–23.80%) vaccinated with Meningococcal A+C polysaccharide vaccine, and in 10.0% (95% CI: 4.35–21.36%) in the comparison group, vaccinated with MPV2 AS. There was no statistically significant difference between the groups (p ≥ 0.05). Results of the study assessing the immunogenicity: on the 28 th day after single-dose immunization of the participants of the clinical trial, both in the group vaccinated with Meningococcal A+C polysaccharide vaccine, and in the control group (vaccinated with MPV2 AC), a statistically significant increase in antibody titer was noted, p ≤ 0.001: 76.0% (95% CI: 62.59–85.70%) versus 74.0% (95% CI: 60.45–84.13%) in the control group, χ2 =0.0533 and p=0.818.. Conclusions. Meningococcal A+C polysaccharide vaccine is characterized by safety, low reactogenicity and high immunogenicity comparable to the MPV2 AC vaccine.

Relevance . In connection with the advent of new diagnostic immunological tests, it became possible to determine a potential focus of infection not only through the identification of patients with tuberculosis, but also through the identification of patients infected with M. tuberculosis, who still do not have manifestations of a local form of the disease. This made it possible to search for persons who were infected with an unknown source of tuberculosis infection in order to conduct an in-depth epidemiological investigation and detect hitherto unknown foci of tuberculosis. Aims . To study the effectiveness of identifying the source of infection in the environment of a patient with a positive immunological test for tuberculosis («indicator» patient). Materials and methods . 1) A retrospective study of the data of all 30 patients with tuberculosis in the period from 2014 to 2019 in Moscow, identified by indicator patients with a positive immunological test, was carried out. 2) A cohort of patients with latent tuberculosis infection with and without HIV infection (Moscow) was studied in the period 2020–2021. to determine the prevalence of latent infection in the close circle of communication of indicator patients. Results . Patients with tuberculosis, forming hidden foci and identified by the indicator patients infected by them with a latent infection, in 56.7% of cases were not examined for tuberculosis for 2–10 years, in 50.0% they suffer from tuberculosis with registered bacterial excretion, in 46.7% of cases are internal or external migrants. The prevalence of latent tuberculosis infection among indicator patients is 10%, which is many times higher than the prevalence of latent tuberculosis infection among the permanent population of Moscow (less than 1%), in HIV-infected risk groups (up to 5%), in known foci of tuberculosis on average in Moscow (5%). The TB notification rate in the environment of indicator patients with latent tuberculosis infection is 38.8 per 100,000 of the corresponding group and exceeds that among the permanent population of Moscow by 5.4 times. Conclusion . A modified epidemiological investigation aimed at examining the environment of persons with latent TB infection among adults makes it possible to identify TB patients who have infected indicator patients and to identify other infected patients.

Relevance . The demographic situation in the Russian Federation over the past decades has been characterized by negative dynamics, while the two key indicators, the ratio of which affects this, are birth and death rates. Of particular interest in this case are malignant neoplasms (MNs) of the organs of the reproductive system, which can both affect the decline in fertility, especially when it comes to the age group under 40, and make a significant contribution to the structure of the population mortality. А im . Analyze the changes in mortality rates from cancer of the reproductive organs among the population aged 15 to 39 years, their dynamics and structure in the Russian Federation for 2011–2020. Materials and methods . To calculate the indicators, an analysis was carried out of the data of the forms of the federal state static observation on the distribution of the deceased by sex, age groups and causes of death by Rosstat (FSN-C51) and statistical information on the age and sex composition of the population of the territories of the Russian Federation. Results . The highest «crude» mortality rates were noted in the Siberian and Far Eastern Federal Districts (5.04 (95% CI = 4.49–5.58) and 5.00 (95% CI = 4.09–5.90) per 100 thousand of the population, respectively), the smallest – n the regions of the North Caucasus Federal District (2.58 (95% CI = 2.06 - 3.11) per 100 thousand of the population). Significant gender differences were also identified. Female mortality from malignancies of the reproductive organs was significantly higher (the "crude” mortality rate among women was found to be 7.57 (95% CI = 7.22–7.92) versus 0.72 (95% CI = 0.61–0.82) among men per 100 thousand) due to the dominance of oncological lesions of the cervix and mammary gland at an earlier age. Conclusion . The identified features of the manifestations of mortality from cancer of the reproductive organs for various territories and population groups can serve as a rationale for strengthening the existing preventive measures, such as vaccination against HPV, as well as for developing new strategies aimed at improving the demographic situation.
的相关性。过去几十年来,俄罗斯联邦人口状况的特点是消极动态,而影响这一动态的两个关键指标是出生率和死亡率。在这种情况下,特别令人感兴趣的是生殖系统器官的恶性肿瘤(MNs),它既可以影响生育力的下降,特别是在40岁以下年龄组,也可以对人口死亡率的结构作出重大贡献。А im。分析2011-2020年俄罗斯联邦15至39岁人口生殖器官癌症死亡率的变化及其动态和结构。材料和方法。为了计算这些指标,分析了俄罗斯国家统计局(FSN-C51)关于按性别、年龄组和死亡原因分列的死者分布的联邦国家静态观察表格(FSN-C51)和关于俄罗斯联邦各领土人口年龄和性别构成的统计资料。结果。西伯利亚和远东联邦区的"粗"死亡率最高(每10万人口分别为5.04 (95% CI = 4.49-5.58)和5.00 (95% CI = 4.09-5.90)),北高加索联邦区最低(每10万人口2.58 (95% CI = 2.06 - 3.11))。还发现了显著的性别差异。生殖器官恶性肿瘤导致的女性死亡率明显较高(妇女的"粗"死亡率为每10万人中7.57人(95% CI = 7.22-7.92),而男性为每10万人中0.72人(95% CI = 0.61-0.82)),原因是宫颈癌和乳腺肿瘤病变主要发生在较早的年龄。结论。在不同地区和人口群体中,生殖器官癌症死亡率的已查明特征可以作为加强现有预防措施的依据,例如接种人乳头瘤病毒疫苗,以及制定旨在改善人口状况的新战略。
