An immunoglobulin M (IgM) antibody capture enzyme immunoassay (MAC-ELISA) of sera from 153 patients with acute febrile diseases of unknown origin verified 60 cases of infections imported from tropical and subtropical countries to Russia, including 46 cases of dengue fever, 8 cases of Chikungunya fever, 4 cases of West Nile fever, and 2 cases of Neapolitan mosquito fever. The cases of dengue fever were associated with a visit to Indonesia (n = 22), Thailand (n = 11), Vietnam (n = 3), India (n = 3), Venezuela (n = 2), Singapore (n = 1), Sri Lanka (n = 1), Malaysia (n = 1), Costa Rica (n = 1), and Dominican Republic (n = 1). Seven dengue fever patients who had returned from Indonesia (n = 5), Thailand (n = 1), and Costa Rica (n = 1) were observed to have hemorrhagic syndrome. The patients with Chikungunya fever returned after a journey to the Maldive Islands (n = 2), Reunion Island (n = 1), India (n = 1), Indonesia (n = 2), and Singapore (n = 1). West Nile fever infection occurred in India (n = 1), Indonesia (n = 1), Costa Rica (n = 1), and Venezuela (n = 1) and mosquito fever cases were registered in the Malta and Majorca islands.

Purpose: analysis of the arbovirus infections incidence in the south of the European part of the Russian Federation in 2015–2019.Materials and methods. Data from statistical documentation (epidemiological examination of the infectious disease cases, reports on the arbovirus infections incidence) reported by Departments of Rospotrebnadzor to Scientific and Methodological Center for monitoring pathogens of infectious and parasitic diseases of 1–3 risk groups for subjects of the North Caucasian and Southern Federal Districts were analyzed. The obtained data were processed using Microsoft Excel 2010 program.Results. In the south of the European part of the Russian Federation Crimean-Congo hemorrhagic fever (CCHF), West Nile fever (WNF), tick-borne viral encephalitis and dengue fever cases are registered annually.An expansion of the territory with registered epidemic manifestations of CCHF and WNF was noted, reflecting an increase in the area of circulation of their pathogens. An expansion of CCHF and WNF epidemic season with the involvement into the epidemic process of people from all age groups including young children was observed. Significant increase in number of imported cases of dengue fever was documented. Markers of tick-borne viral encephalitis, Batai, Inko, Sindbis, and Tyaginya fevers were detected in residents of a number of territories. A high levels of population humoral immunity to West Nile, Batai, Inko, Sindbis Tyaginya, Ukuniemi, Bhanja, Dkhori viruses were identified in the Astrakhan region.Conclusion. The data obtained indicate the need for epidemiological surveillance both for arbovirus infections with a pronounced epidemiological and clinical manifestations, and for infections, the proportion of which in the structure of infectious pathology in southern Russia has not been sufficiently studied, but carrying a potential risk of spreading.

Between 28 June and 17 September 2018, 27 cases of human West Nile virus infections were recorded in Austria; four cases of West Nile neuroinvasive disease, 11 cases of West Nile fever, six infections detected by blood donation screening and six imported cases. In addition, 18 cases of human Usutu virus infections (all blood donors) were recorded. This is the highest number of annual infections recorded in Austria since the introduction of both viruses.

The epidemic rise in the incidence of West Nile fever (WNF) in the season of 2018 was observed in the countries of the European Union (EU) and bordering states and exceeded the values of all previously recorded epidemic rises of 2010–2012. An increase in the incidence rate was registered in the USA and Canada, however, it did not exceed the indicators of epidemic rises of 2007–2012. In the territory of the Russian Federation, the WNF epidemiological process became more intense mainly in the territory of the Southern and North Caucasian Federal Districts. In general, in Russia, the incidence rates were 2 times lower than the average annual rates, but significantly exceeded those of 2017. The epidemic process had a number of peculiarities in the seasonality, the structure of morbidity and the clinical manifestation of WNF. Genotyping of the isolated WNV RNA fragments from clinical and biological material showed that I, II and IV West Nile virus genotypes were circulating in the European part of Russia. Forecast of epidemic situation development in 2019 reveals further increase in the incidence and does not exclude the possibility of a significant localincrease of WNF incidence in certain regions of Russia.

The paper presents an analysis of West Nile Fever incidence in the Russian Federation in 2020, summarizes the results and identifies problematic issues of the pathogen monitoring. Manifestations of West Nile Fever in 2020 were characterized by a low incidence rate (10 times lower than the average long-term value) with sporadic cases registration in the endemic areas of the Southern (9 cases) and Central (1 case) Federal Districts. A discrepancy between the morbidity structure (distribution by age, sex, social status) and the trends that have developed in Russia in recent years is shown. The analysis of officially recorded cases doesn’t characterize the epidemic process of West Nile fever in Russia during 2020-season as a whole. The generalized results of monitoring of the West Nile virus circulation in environmental objects in 2020 indicate a decrease in the effectiveness of its implementation and a low detectability of pathogen markers. A decrease in the volume of diagnostic studies for the active detection of patients with West Nile fever in the epidemic season (5.7 times lower compared to 2019), as well as serological screening of healthy population samples (1.6 times) has been established. The results of a molecular-genetic study of the pathogen showed that lineage 2 of the pathogen was circulating in the European part of Russia. The circulation of the lineage 4 of the virus in the enzootic cycle in the Republic of Kalmykia was found out. The genome sequences of 11 West Nile virus isolates allocated in 2019 and 2020 were obtained. Phylogenetic analysis revealed that all isolates allocated in the Volgograd Region and isolates from the Rostov and Astrakhan regions belong to the Volgograd clade of the lineage 2 of the West Nile virus. Based on the assessment of abiotic and biotic factors, possible local increases in the incidence of West Nile fever in 2021 in the regions of the Southern and North Caucasian Federal Districts and in the south of Western Siberia have been substantiated.

The aim of the work was the study of serum from patients with suspected dengue fever by both enzyme immunoassay and immunochromatography. Markers of dengue fever were detected in 6 of 10 travelers returning from Southeast Asia. Analysis of the of immunoglobulin M and G antibody titers ratio (IgG/IgM) showed that the five travelers were infected with dengue fever virus for the first time. At the same moment one of patients was infected with dengue virus repeatedly that is a risk factor for severe complications. Thus, early laboratory diagnosis of dengue based on the detection of NSl=antigen and IgG/IgM ratio has been shown not only to help in making a differential diagnosis, but also in saving the life of the patient, because the dengue fever is characterized by rapid progression to the development of severe complications which are not compatible with life. In cases of fever in travelers which have been coming back from countries where hemorrhagic fever is endemic, we propose to make a differential diagnosis with dengue fever that was confirmed by our study.

The questions of spreading of West Nile fever in the territory of theRussian Federationand abroad are considered. The information on the main carriers and vectors of this infection and their interaction with virus population is presented. The tendency of spreading of the West Nile fever virus in theRussian Federationand the possibilities of its maintenance during the inter-epidemic period are shown. Recommendations are given on the organization of serologic monitoring ofWest Nilefever in natural and anthropurgic biocenoses.
