Objective: To analyze the results of epizootic monitoring of natural foci of particularly dangerous infections common to humans and animals in Rostov Oblast to establish their activity.Materials and Methods: The data of epizootic monitoring conducted by zoologists; the results of laboratory research of field material obtained in natural foci of infectious diseases. Descriptive, zoological, genetic, serological methods, and retrospective epidemiological analysis were used.Results: The results of the conducted epizootic monitoring showed the presence in Rostov Oblast of natural foci of particularly dangerous infectious diseases common to humans and animals. While the natural focus of the plague is in a depressed state and does not show activity, in the foci of tularemia, West Nile fever (WNF), Crimean hemorrhagic fever (CHF), ixodic tick-borne borreliosis (ITB), hemorrhagic fever with renal syndrome (HFRS), Q fever, Batai fever, California serogroups, Syndbis revealed the antigens of these pathogens in biological material obtained from small mammals and blood-sucking insects, which indicates the epizootic activity of these foci. In the natural foci of WNF, CHF, ITB, HFRS, cases of these disease among the population were recorded, which confirms the epidemic activity of these foci.Conclusion: The obtained results of epizootic monitoring over the period from 2008 to 2020 emphasize the relevance and necessity of continuing these studies in natural foci in Rostov Oblast.

Objective. To identify the potential epizootic and epidemiological risks arising from the development of the infrastructure of Platov Airport in the territory adjacent to the airport for the development, if necessary, of a set of anti-epidemic and preventive measures. Materials and methods. Epizootological monitoring was carried out in the vicinity of Platov airport, as well as on the territory of the complex itself for three seasons (20192021). The capture of small mammals was carried out according to the standard method of trap-lines with Hero crushers; 1200 trap-days were accumulated. Route records of bats with the determination of their species were carried out. The species belonging of blood-sucking arthropods was determined using determinants. Regulatory support for the above monitoring was formed in accordance with the current normative and methodological documents: SanPiN 3.3686-21 "Sanitary and Epidemiological Requirements for the Prevention of Infectious Diseases"; MP 3.1.0211-20 "Trapping, Accounting and Forecasting the Number of Small Mammals and Birds in Natural Foci of Infectious Diseases"; MU 3.1.3012-12 "Collection, Accounting and Preparation for Laboratory Examination of Blood-sucking Arthropods in Natural Foci of Dangerous Infectious Diseases". Laboratory studies of samples of extracted biomaterial for the search of markers of pathogens of natural focal infections were carried out taking into account the requirements of current regulatory documents. Samples for laboratory testing were formed in compliance with the principle of "one point of collection of material, one time of collection of material, one type of material". Results. The results of epizootological monitoring of the territory of the Platov airport (Rostov-on-Don) are presented, according to which a real possibility of the development of epizootics of dangerous infectious diseases among small mammals living in the adjacent territory to the Platov airport has been established. In order to eliminate potential risks that can lead to complications of the epidemiological situation, it is necessary to carry out planned deratization and acaricide treatments on the territory of Platov airport. The continuation of regular epizootological monitoring of the airport territories and adjacent territories remains very relevant. Conclusions. The results of epizootological monitoring of the territory of the Platov International Airport (Rostov-on-Don) revealed the presence of mouse-like rodents penetrating from the surrounding fields, including those belonging to groups I and II of infectious sensitivity to tularemia, which form potential epizootological risks. A comprehensive laboratory study of biological material obtained from mouse-like rodents captured during epizootological monitoring did not reveal markers of pathogens of natural focal infections. At the same time, systematic regular epizootological monitoring of the airport territory is necessary due to the presence in the territories surrounding the airport complex of natural foci of particularly dangerous infections common to humans and animals, where mouse-like rodents live and reproduce, including house mice and rats, capable of migrating and inhabiting residential and warehouse premises and in case of activation of epizootic process to introduce infection into the territory of the airport complex, especially in autumn and winter.

In the context of the pandemic of the new coronavirus infection COVID-19 (hereinafter, COVID-19), the priority activity of medical organizations was the organization of training of medical workers on epidemiology and prevention of COVID-19, which required the development of a new architecture of the educational process. In order to improve the knowledge of medical staff, new educational technologies were used, which made it possible to cover a wide range of medical workers in a short time and to improve their level of qualification in epidemiology and prevention of COVID-19. Purpose. To summarize the experience of using remote content to improve the skills of medical professionals in epidemiology, prevention and biosafety when working with COVID-19 patients using modern training forms and methods. Materials and methods. A program of seminars for medical workers was developed, which included sections of epidemiology, prevention of COVID-19, and rules of compliance with the anti-epidemic regime when working with COVID-19 patients. The training of medical workers was carried out using modern IT technologies. Discussion. New technologies made it possible to expand the training opportunities for medical workers. To increase the level of knowledge and exchange of experience, it became possible to invite highly qualified specialists for tutoring. Conclusion. The use of modern forms of education makes it possible to expand significantly the possibilities of the educational process, make available the necessary information about the epidemiology and prevention of COVID-19 to a wide range of health workers, and increase the effectiveness of the training. The role of a teacher with the introduction of such technologies acquires a new quality, called a tutor.

Objective. To study the features of the formation of the epidemic situation for tuberculosis and to evaluate the effectiveness of antiepidemic events in separate age groups. Materials and methods. A retrospective analysis of the incidence of tuberculosis in Rostov-on-Don from 1992 to 2017 was conducted. The dynamics of the incidence of active tuberculosis, respiratory system tuberculosis and forms with bacillus discharge with the determination of the trend and its quantitative assessment was studied; the age structure of tuberculosis patients was analyzed depending on the direction and severity of the trend. Results. The incidence of tuberculosis has been increasing in Rostov-on-Don since 1993, and from 2003 to 2008, the average long-term incidence of active tuberculosis, respiratory tuberculosis and forms with bacillus excretion was maximum. Since 2009, the direction of trends has changed, the period from 2009 to 2013 is characterized by a "pronounced" downward trend and since 2014, the incidence rates have been minimal. In the age structure of patients with active tuberculosis, the proportion of persons aged 40-49 is decreasing, and in 20142017, the proportion of persons aged 5059 years is also falling. Since 2009, the proportion of persons aged 1829 has increased, and in 20092013 the proportion of children has grown. In 20142017, the proportion of persons over 60 years of age increased among those who fell ill. Conclusion. The most effective events are carried out in the group of 4059 years, less effective among children and persons aged 1517 and 3039 years. The results of the research will allow us to adjust preventive measures among children, teenagers and young people.
