Analysis of the Epidemiological Situation of Hemorrhagic Fever with Renal Syndrome in the Russian Federation in 2022 and Forecast of its Development for 2023

The paper provides the analysis of epidemiological process of hemorrhagic fever with renal syndrome (HFRS) in the Russian Federation in the context of federal districts in 2022 and a forecast of the HFRS incidence for 2023. According to the results of the analysis, there was a three-fold increase in the morbidity rates of HFRS in Russia in 2022 as compared to the indicators of 2021. The evidence of epizootiological survey and laboratory studies in certain federal districts of the Russian Federation indicate the continuing tense epidemiological situation on HFRS. In a number of regions of the country, high risk of infection with HFRS is predicted due to the favorable natural and climatic conditions of the winter period 2022/2023 for reservoir hosts of pathogenic for humans Hantaviruses. The findings of infected rodents attest to a high probability of complication of the epidemiological situation in the territories of increased epidemic hazard as regards HFRS

Results of a Joint Epizootiological Survey of Transboundary Natural Plague Foci of the Russian Federation and Potentially Focal Territories of the Republic of Kazakhstan in 2019–2022

Consolidation of the efforts in implementation of epidemiological surveillance and control over plague and other dangerous natural-focal infections is an essential aspect in ensuring epidemiological well-being as regards particularly dangerous infectious diseases in the territory of natural plague foci and potentially focal territories located within the borders of the Russian Federation and the Republic of Kazakhstan. The aim of the work was to carry out a joint epizootiological survey of the transboundary territories of the Volga-Ural sandy natural plague focus and the territory of the East Kazakhstan region of the Republic of Kazakhstan (RK) potentially focal for plague over the period of 2019–2022. Materials and methods. Samples of field materials, collected during the epizootiological survey of the territory of Kazakhstan, were studied using bacteriological, molecular-genetic, and immune-serological methods. Results and discussion. We have obtained the current evidence on the spatial-biocenotic structure, the circulation of pathogens of dangerous natural-focal infectious diseases in the transboundary territories of Eastern and Western Kazakhstan. It has been established that the conditions that contribute to the possibility of human infection with plague and other dangerous infectious diseases in case of the aggravation of epizootic situation in the foci or importation of the pathogens into the territory are in place
