Epidemiological Situation

The review presents an analysis of epidemic and epizootic situation of Crimean-Congo hemorrhagic fever in the Russian Federation in 2010–2019, summarizes the results of epizootiological monitoring of the CCHF natural focus territory in the south of European part of Russia. An unfavorable epidemiological situation regarding CCHF is maintained in the Russian Federation. In 2010–2019, 999 CCHF cases were registered in nine regions of Southern and North-Caucasian Federal Districts. In 2019, an increase in the CCHF incidence level in the entities of the SFD and NCFD was observed as compared to 2017–2018. The expansion of the territory with registered epidemic manifestations of CCHF continues. In 2010–2019, the number of imago and pre-imaginal phases of Hyalomma marginatum – the main vector of the CCHF virus in Russia, remained consistently high. High numbers of H. marginatum ticks and their CCHFV infection rates can contribute to the development of an unfavorable epidemiological situation in the south of the Russian Federation with a possible increase in the CCHF incidence in 2020.

Epidemiological Situation

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.

Objective– analysis of epizootiological manifestations of natural focal infections in the territory of the south of the European part of the Russian Federation in 2017.Materials and methods. Statistical documentation data from the Rospotrebnadzor Administrations, Centers of Hygiene and Epidemiology in the constituent entities of the Russian Federation, and Plague Control Research Institutes and Stations were used. The information was processed using Microsoft Excel 2010 software.Results and discussion. Epizootiological survey for 19 nosological forms of natural focal infections in the territory of the south of the European part of the Russian Federation was conducted. The total of 70155 samples of field material was tested; markers of 14 pathogens of natural focal infections were identified. The circulation of Crimean-Congo hemorrhagic fever virus was revealed in 11 constituent entities, tularemia and Lyme borreliosis pathogens – in 8 entities, West Nile virus – in 7. Markers of leptospirosis, Q fever, human granulocytic anaplasmosis and human monocytic ehrlichiosis pathogens were detected in 6 constituent entities, markers of the agent of hemorrhagic fever with renal syndrome – in 5 entities; markers of intestinal yersiniosis pathogen – in 3 constituent entities of the Russian Federation, pathogens of tick spotted fevers group, tick-borne viral encephalitis and pseudotuberculosis – in 2. The circulation of the virus Sindbis was identified in the Rostov Region.

Epidemiological Situation

The review presents an analysis of the epidemiological and epizootiological situation on Crimean hemorrhagic fever in the Russian Federation in 2020. During the stated period, 32 CHF cases were registered, which is the minimum indicator since the activation of the natural focus of CHF in 1999. The mortality rate was 3.1 %. The incidence was recorded in the Rostov, Astrakhan Regions, Stavropol Territory, the Republics of Dagestan and Kalmykia. A significant decrease in the incidence of CHF was noted in all entities of the Southern Federal District and the North-Caucasian Federal District. An imported from the Republic of Crimea case of CHF was detected in Moscow. The seasonality of morbidity, occupational, and age composition of CHF patients, modes of transmission, features of the clinical course of the disease in 2020 corresponded to the data of long-term observations. Epizootiological monitoring of the territory of the CHF natural focus showed that the abundance of Hyalomma marginatum adults and the percentage of Ixodidae tick pools positive for the presence of CCHF virus markers corresponded to the average long-term indicators at stationary observation points in 2020 , which indicates the persisting epizootiological disadvantage of the territory of the natural CHF focus in the Russian Federation. The persisting high numbers and infection rate of H. marginatum ticks can contribute to the development of an unfavorable epidemiological situation in the south of the country with a possible increase in the incidence of CHF in the Russian Federation in 2021.

Purpose. A dynamic comparative analysis of the results of identification ofVibrio cholerae(V. cholera) isolates from water and human specimens isolated during the monitoring of cholera throughout the Russian Federation in 2013–2019.Materials and methods. Total 385 strains ofV. choleraeO1 serogroup (including one toxigenicV. choleraeO1 El Tor Inaba — Rostov region, 2014) and the R-variant from environment objects were identified in the territory of 21 regions of the Russian Federation.Results. It was found that 91% of the strains were isolated in 7 regions of the Russian Federation: Republic of Kalmykia, Krasnodar Krai, Transbaikal Krai, Khabarovsk Krai, Primorsky Krai, Rostov region and Irkutsk region. 2.3% of strains were atypical in their agglutinability, and 75.3% of strains had atypical phagosensitivity. Phagotypes were identified for 13.2% of strains isolated in 11 administrative territories. Phageotype 11 included 48.8% of the strains isolated mainly in the Transbaikal Krai. Non-toxigenic strains ofV. choleraenonО1/nonO139 (n = 46) were isolated from 43 patients with acute intestinal infections and otitis in 8 regions of Russia. PCR-typing of 377 non-toxigenicV. choleraestrains demonstrated that they belong to 13 clusters and 71 genotypes. Strains with unique genotypes (probable cases of importation) and with the same genotypes repeatedly isolated in different years in one or several territories of the Russian Federation were identified, indicating the prevalence of strains in environment throughout the country.Conclusion. The results allowed us to characterize the epidemiological situation of cholera in Russia (in terms of the environment contamination withV. choleraeO1) as unstable, but not significantly changed over the past 7-year period. These data are important for substantiating the forecast for further development of the epidemiological situation.
