Monitoring Studies Of
Arbovirus Infections Transmitted by Mosquitoes on The
Territory of the Volgograd Region

Relevance. Natural and climatic conditions, a variety of species composition of arthropods and vertebrates determine the possibility of circulation of arboviruses in the Volgograd region. The existence of natural foci of some arbovirus infections and the possibility of the formation of others suggests the need for annual monitoring of the causative agents of arbovirus diseases. Аim. Evaluation of the results of monitoring of arbovirus infections in the Volgograd region in 2019.Materials and methods: 806 blood serum samples from donors, 44 blood serum samples from febrile sick people, 300 blood serum samples from horses and 94 pools of blood-sucking mosquitoes were examined by immunofernal analysis. Result of the study of serum samples from donors in the Volgograd region, in 140 (17.4%) of 806 were found to have antibodies to the pathogen of West Nile fever (in 35 (4.3%) – IgM, in 105 (13.0%) – IgG), in 7 (2.2%) of 319 – to the Crimean hemorrhagic fever virus (in 4 (1.3%) – IgM, in 3 (0.9%) –IgG), and in 7 (2.9%) of 240 – IgG to the viruses of the California serogroup. Specific antibodies against viruses of Sindbis, Batai and Uukuniemi in the samples was not detected. The largest number of positive samples with the presence of IgG and IgM to the West Nile virus was found among residents of Volgograd (61 out of 240, 25.4%) and Volzhsky (25 out of 100, 25, 0%). Among 44 blood serums of febrile patients, 1 sample (2.3%) was found to contain an antigen of the Sindbis virus, and 2 samples (4.5%) – antigens California serogroup viruses. Specific immunoglobulins against West Nile virus were detected in 84 (28%) of 300 blood serums of farm animals (horses). In the study of 94 samples of field material (blood-sucking mosquitoes), West Nile virus antigen was detected in 14 (14.9%), Sindbis virus – in one sample (1.0%), Batai virus – in four samples (4.2%). Conclusions: the obtained results, along with the circulation of West Nile virus and Crimean hemorrhagic fever virus virus in the Volgograd region, indicate the presence of Sindbis, Batai and California serogroup viruses and necessitate further study of their role in the infectious pathology of the population.

Резюме Актуальность. Широкое распространение лихорадки Западного Нила (ЛЗН) в Российской Федерации и различная интенсивность проявлений эпидемического процесса определяют актуальность разработки методологии эпидемиологического районирования и дифференциации территории страны по уровню потенциальной эпидемической опасности, что позволит оптимизировать мониторинг за возбудителем ЛЗН и комплекс профилактических мероприятий. Цель. Разработать методику дифференциации территории по степени потенциальной эпидемической опасности заражения вирусом Западного Нила (ВЗН) и апробировать ее на примере Волгоградской области. Материалы и методы. На основе разработанной нами методики с использованием пространственного кластерного анализа и метода балльной оценки показателей выполнено эпидемиологическое районирование Волгоградской области по риску инфицирования вирусом Западного Нила. В работе использованы:
