Background. In spring and summer, the population of the Baikal region regularly comes into contact with the pathogens transmitted through the bites of ixodid ticks. In the Center for Diagnosis and Prevention of Tick-Borne Infections (Irkutsk, Russian Federation), we annually detect anaplasmas of the Anaplasma phagocytophilum species, as well as Ehrlichia chaffeensis/E. muris in both ixodid ticks and blood samples from people who have been bitten by ticks. At the same time, there are no data in open sources on the incidence of human granulocytic anaplasmosis and human monocytic ehrlichiosis in the Baikal region. Currently, there is very little information on the studies of intensity of the immune response to anaplasmas and ehrlichia in people living in the surveyed area, although this information is critical for assessing the frequency of contacts and the risk of infection of people in a territory endemic for tick-borne infections. The aim. To update information on the presence and prevalence of specific immunoglobulins M and G to A. phagocytophilum and Ehrlichia sp. among the population of the Irkutsk Region affected by tick bites. Materials and methods. In total, 204 samples of blood serum from the residents of the Irkutsk Region who were registered to be bitten by ticks were analyzed for the presence of IgM and IgG to human monocytic ehrlichiosis and human granulocytic anaplasmosis agents. Results. IgG to A. phagocytophilum were found in 9 samples, IgG to E. chaffeensis/E. muris – in 1 sample; no IgM to both pathogens were found in any sample. Conclusions. The results obtained indicate regular infection of the population with anaplasmas and ehrlichia which is a testifies to the existence of active natural foci of human monocytic ehrlichiosis and human granulocytic anaplasmosis in the Baikal region. To clarify the real epidemic role of these infections, a detailed study of the immune status is required both among healthy individuals and among patients with symptoms of an infectious disease.

“…При оценке приверженности к вакцинации самих врачей в нашем исследовании было выявлено, что 96% (311/324) респондентов делают обязательные прививки по НКПП. В программе собственной иммунизации преобладает клещевой энцефалит (24,3%), что объясняется региональными особенностями распространения данного заболевания на территории Иркутской области [15,16]. Против пневмококковой инфекции прививаются 13,8% врачей, против менингококковой инфекции -10,4%, что также отражает знания врачей об эпидемиологической ситуации в регионе.…”

РезюмеЦель: изучение отношения к вакцинации врачей разных специальностей г. Иркутска.Материалы и методы. По данным кросс-секционного описательного многоцентрового исследования проведена оценка информированности в вопросах вакцинопрофилактики 324 врачей разных специальностей. Из указанной выборки респондентов были выделены 3 группы: группа 1 (n = 218) -врачи, назначающие вакцинацию детям (педиатры, неонатологи); группа 2 (n = 54) -врачи, назначающие вакцинацию взрослым (терапевты, акушеры-гинекологи); группа 3 (n = 52) -врачи, которые могут консультировать по вопросам вакцинации (неврологи, хирурги и другие специалисты). Статистический анализ результатов проведён с использованием программы «Statistica 6.0». Критический уровень значимости при проверке статистических гипотез о существовании различий показателей между группами p принят равным 0,05.

Introduction. The Republic of Altai is one of the regions of the Siberian Federal District endemic for tick-borne encephalitis with high altitude mountain belts with characteristic landscape and climatic conditions. The purpose of this study is to analyze the epidemiological situation of tick-borne encephalitis in the Republic of Altai from 2000 to 2017. Material and methods. In conducting a retrospective epidemiological study, data from sanitary-epidemiological and medical services for 2000-2017 were used. Statistical data processing was carried out with the software “Statistica 12.0”, the construction and analysis of cartograms - with the software ArcGIS. Results. The average long-term incidence rate of this infection in the period from 2000 to 2017 amounted to 21.7 ± 0.76 0/0000, which is 2.2 times higher than the similar indexby for the SFO (10.1 ± 0.23 0/0000). The number of persons affected by tick infestation in the period from 2000 to 2017 increased 3.5 times from 517.7 ± 15.95 0/0000 to 1810.5 ± 28.62 0/0000, respectively (p <0.001). Ranking on the level of the average long-term incidence allowed identifying three groups of the potential risk of infection of the population. Discussion. The factor analysis revealed the presence of an inverse correlation between the incidence of tick-borne encephalitis and the levels of seroprophylaxis (r = -0.93), acaricidal treatments (r = -0.95), vaccination (r = -0.10). The calculated levels of these factors were determined according to the results of the construction of spatial models of their mutual influences, capable of reducing the number of cases in the region to 6 per year. Conclusion. An analysis of the epidemic situation based on factor analysis and spatial modeling of the mutual influence of factors made it possible to determine the necessary volumes of preventive measures to reduce the incidence of the population to a given level. Such a calculation may be applicable in an endemic region to ensure the medical and economic effectiveness of preventive measures.
