“…This suggests that the circulation of insect-specific viruses in mosquitoes may influence the spread of mosquito-borne viruses that are already known and pathogenic to humans. The expansion of West Nile virus’ range border to the north has increased the severity of this problem [ 61 ]. At the same time, the host’s innate immune system responds differently to viral infections.…”

In the last few years, there has been a dramatic increase in the number of discovered viruses that are transmitted by arthropods. Some of them are pathogenic for humans and mammals, and the pathogenic potential of others is unknown. The genus Orthoflavivirus belongs to the family Flaviviridae and includes arboviruses that cause severe human diseases with damage to the central nervous system and hemorrhagic fevers, as well as viruses with unknown vectors and viruses specific only to insects. The latter group includes Lammi virus, first isolated from a mosquito pool in Finland. It is known that Lammi virus successfully replicates in mosquito cell lines but not in mammalian cell cultures or mice. Lammi virus reduces the reproduction of West Nile virus during superinfection and thus has the potential to reduce the spread of West Nile virus in areas where Lammi virus is already circulating. In this work, we isolated Lammi virus from a pool of adult Aedes cinereus mosquitoes that hatched from larvae/pupae collected in Saint Petersburg, Russia. This fact may indicate transovarial transmission and trans-stadial survival of the virus.

Objective: to assess the quality and effectiveness of West Nile fever (WNF) causative agent’s monitoring in the Volgograd region and to develop a set of measures to its optimization. Materials and methods: data on the detection of WNV cases, results of serological and zooentomological monitoring in 2009–2021. A comprehensive methodological approach was applied, including statistical and epidemiological methods. Results: based on the assessment of WNF causative agent’s monitoring key aspects in the Volgograd region, it was shown that one of the priority problems is the insufficient and untimely detection of cases among the population. Among the urgent problems of serological monitoring are the lack of a clearly established frequency of serological examination in the population of the region’s administrative territories and the termination of one of the indicator population groups examination, regulated by the current regulatory and methodological documents. An assessment of the parameters of monitoring studies of the external environment indicates an insufficient territorial coverage and a decrease in the volume of studies, primarily in relation to the main carriers of the West Nile virus, which determines the overall low detection rate of West Nile virus markers. Conclusion: recommendations are proposed for optimizing monitoring, which will enhance the efficiency of WNF epidemiological surveillance and develop a scientifically based forecast of the development of the epidemiological situation.

Relevance. The relevance of this work is determined by obtaining new data on the geography of distribution and manifestations of the epidemic process of West Nile fever in Russia as a result of exploratory scientific research and systematization of the results of long-term (since 2010) monitoring of the causative agent of this infection. Aims: assessment of the state and effectiveness of epidemiological surveillance of WNV and optimization of its methodological, scientific and practical support. Materials & Methods. We used the reporting data of the Rospotrebnadzor Directorates for the constituent entities of the Russian Federation, received by the Reference Center for monitoring the causative agent of West Nile fever, materials from scientific publications, monographic publications and dissertation research. The main research method is epidemiological. Results and discussion. The problems of monitoring the causative agent of West Nile fever are identified, which make it difficult to obtain objective data on the manifestations of epidemic and epizootic processes, the frequency of contacts of the population with the causative agent of the disease, and the possibility of developing epidemiological forecasts. The key areas for improving the monitoring system for the causative agent of West Nile fever are considered: conducting active reconnaissance surveys aimed at clarifying the nosoarea, performing an assessment zoning of the territory of Russia, establishing minimum volumes of epizootological monitoring, ensuring the readiness of medical organizations to identify and diagnose cases of diseases, strengthening organizational and control functions Directorates of Rospotrebnadzor for the constituent entities of the Russian Federation, the frequency of studies in administrative territories to study the immune layer of the population to the West Nile virus and the differentiation of the immune response to the tick-borne encephalitis virus. Conclusions. The proposed set of measures will improve the objectivity and reliability of information received within the framework of the functioning of the epidemiological surveillance system, timely adjust preventive measures and take maximum control over the development of the epidemiological situation in the territory.
