Transmissible arboviruses of the Ukrainian Black Sea region

Abstract

The article presents a retrospective analysis of epidemiological and ecological-virological studies of authors' teams in the field of landscape-faunistic features and noso-geography of biocenoses. The endemicity of arboviruses in the south of Ukraine was established for the first time. The spread of transmissible forms such as West Nile fever and tick-borne encephalitis on models of blood-sucking arthropods (carriers), warm-blooded animals and birds - migratory / local birds (carriers) in the zones of their concentration (reserves, "bird colonies") in natural biocenoses of Odessa, Kherson, Nikolaev regions and Crimea. Among the population of the southern regions, an immunological background has been established regarding their transmissible nature. So, from the cerebrospinal fluid of a patient with neuroinfection, a strain of arbovirus was isolated on transplanted cells. Genetic features, epidemic risks are determined, biotic and abiotic factors of their natural circulation are reflected in nature [49, 50]. According to the theory of the dynamics of averages, taking into account the influence of environmental factors and infection of biological objects, a mathematical model of the intensity of the epidemic process in West Nile fever has been created.
