The paper presents analysis of epidemiological situation on hemorrhagic fever with renal syndrome around the world and in the Russian Federation over the period of 2009–2018. 5855 cases of hemorrhagic fever with renal syndrome were registered in Russia in 2018 (3.99 per one hundred thousand of the population). Downward trend is observed as compared to 2017 (by 29.6 %). Cases of cluster infection were not reported. It is established that the highest level of morbidity, exceeding the average level across Russia 3.9 times, was noted in the Volga Federal District, where 77.5% of the total cases occurred. The territory of the Russian Federation was differentiated by the HFRS incidence rates. The areas with high levels of morbidity included the entities of the Russian Federation with intensive index range between 9.08 and 41.39 per one hundred thousand of the population, among them Republics of Bashkortostan, Mari El, Tatarstan, and Mordovia, Udmurt and Chuvashi Republics, Kirov, Nizhny Novgorod, Penza, Samara, Ulyanovsk, Kostroma, Yaroslavl, and Jewish Autonomous Regions. The forecast for preservation of tense epidemiological situation on HFRS incidence in the territory of the Volga Federal District was substantiated.

“…Both species overlap much spatially, occur within the same habitats, and demonstrate interspecific overlap in home ranges. They are active under the snow throughout the winter, even at air temperatures of −30° to −40°С, are generally similar in demography and population dynamic (Kravchenko, 1999 ), and experience a similar load of parasites and infections (Abramov et al, 2011 ; Krivopalov, 2011 ; Galbreath et al, 2013 ). At the same time, red‐backed and gray‐sided voles differ in their dietary habits and energetic performances.…”

We studied the seasonal variation of adaptive humoral immunity (AHI) in northern red‐backed vole ( Clethrionomys rutilus Pallas, 1779, RBV) and gray‐sided vole ( C. rufocanus Sundevall, 1846, GSV) in Tomsk region of Western Siberia. Immunoresponsiveness (IR) to sheep red blood cells was assessed by the number of antibody‐producing cells in the spleen. The use of a generalized linear model to analyze the effects of species, sex, year of research, and season of withdrawal of individuals from nature on IR showed a significant effect of species identity, season of animal capture, and the interaction of species with season. The RBV demonstrated higher immune responses during a year, and both species had higher IR in winter. Suppression of IR in spring was greater, started earlier, and lasted longer (March–May) in GSV. In RBV, immunosuppression was restricted to April. The significant negative within year correlations of IR with body mass and masses of reproductive organs in GSV indicated a trade‐off between AHI and growth and reproduction processes. A probable explanation for the difference between species in the seasonal variation of AHI may be related to the difference in tropho‐energetic requirements of each vole species. GSV is a predominantly herbivorous rodent and its thermoregulation seems less efficient than of RBV. The deeper spring immunosuppression in GSV may explain in part its higher mortality during the season of colds.

“…границы природных очагов расширяются, постепенно вовлекая в этот процесс территории, ранее считавшиеся свободными от глпс [12][13][14][15][16]. за последнее десятилетие обнаружены новые очаги хантавирусной инфекции в республике алтай, новосибирской, иркутской и кемеровской областях, а также выявлены новые серотипы хантавируса и установлены новые резервуары инфекции в природе [17] ской опасности, который рассчитывали формальнотерриториальным способом для каждого субъекта пФо (или его административных единиц) [18]. выбор подхода к районированию основан на ретроспективном анализе комплекса эпидемиологических и эпизоотологических данных, характеризующих эпидемический процесс глпс.…”

HFRS is a relevant threat to the sanitary-epidemiological welfare of the population of the Russian Federation. It takes a leading position in the structure of natural-focal ifections of viral etiology incidence around the country. The most unfavorable situation on HFRS morbidity rates (more than 80% of the overall incidence) is observed in the constituent entities of the Volga Federal District (VFD). The purpose of the work is to differentiate the territory of the Volga Federal District in terms of the potential epidemic hazard (PEH) of HFRS infection. Materials and methods. We used information on the HFRS incidence contained in the statistical reporting form No. 1 “Information on infectious and parasitic diseases” and the data on epizootic activity of natural HFRS foci from the established forms of surveys and forecasts of the state of population and the numbers of small mammals over the period of 2014-2018. The assessment of the PEH level of HFRS infection was carried out according to the original method developed with the participation of the authors. The software used was the analytical platform Deductor Professional and the geo-information system Arc GIS. Results and discussion. Among the constituent entities of the Volga Federal District an extremely high level of risk of HFRS infection (6 points), the first type of territories, was established for the Udmurt Republic, the Republics of Bashkortostan, Tatarstan, Mordovia, and Chuvash Republic. The second type of territories characterized by high level of risk, where the PEH was 5 points – Samara, Ulyanovsk, Nizhny Novgorod, Kirov, Saratov, Orenburg regions and the Republic of Mari El. The territories in which there is an increased risk of HFRS infection cover the territory of the Penza Region (PEH – 4 points). The average risk of infection was noted only in the Perm Region (PEH – 3 points). Prompt implementation of a complex of nonspecific preventive measures at sites with a pronounced increase in the potential epidemic hazard of HFRS infection will significantly reduce the incidence rate in the VFD and the Russian Federation as a whole.
