Assessment of the efficiency of acaricidal treatment territories with respect to tick virus encephalitis in the regions of the Siberian federal district
Aim of the study is to assess the area of acaricidal treatments for the incidence of tick-borne viral encephalitis in the population of the regions of Western Siberia within the Siberian Federal District of the Russian Federation. Materials and methods. In conducting a retrospective epidemiological analysis, materials were used by the sanitary-epidemiological service of the Russian Federation and the regions of the Siberian Federal District, regional ministries and health services for the period from 2000 to 2017. Statistical analysis of data with the calculation of mutual dependencies between the phenomena was carried out using the program Statistica 12.0, mapping - in the program ArcGIS. Results. The contribution of acaricidal treatments of the territory to the formation of a tendency to a decrease in the incidence of tick-borne viral encephalitis is determined by the presence of a strong correlation (r = -0.82; p < 0.001). Taking into account the high virus-likeness of ticks in the endemic regions of the Siberian Federal District, averaging 4.0 ± 0.15%, reducing the number of ticks per km of the path is an effective measure to reduce the incidence, as evidenced by the presence of strong correlations (r = 0.64; p < 0.001). On the basis of the spatial distribution of the level of tick-borne virus mites over the territory of the regions of the Siberian Federal District, groups of regions of high, medium and low potential danger of infection of the population are identified. Conclusion. The assessment of the effectiveness of acaricidal treatments in relation to the incidence of tick-borne viral encephalitis in the endemic regions of Western Siberia has determined the need to increase their volume in areas characterized by the greatest potential risk of infection of the population.
