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

Abstract

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.
