On the problem of vector-borne viral diseases and the area of spread of pathogen vectors

The results of the generalization of data on the spread of vector-borne viral diseases, the distribution area of the potential vector of West Nile viruses, bluetongue, Schmallenberg disease, and Crimean-Congo hemorrhagic fever in certain regions of Ukraine are presented. It has been established that the distribution areas of vector-borne diseases on the planet are determined by a complex of biotic and abiotic circumstances, in which the key role is played by live vectors of these infections
