Effect of the natural and climatic factors on epidemiological situation related to natural focal infections

This article is dedicated to the analysis and generalization of Russian foreign research results on natural climatic factors effect intensity epidemic process manifestations focal infections pathogens vectors vital activity which are most widespread in Federation. Over past seven years tick-borne have been accounting for more than 50 per cent diseases general nosological structure. Among this group Lyme borreliosis leads prevalence frequency cases identification. Tick-borne viral encephalitis still a serious danger national health. Crimean-Congo hemorrhagic fever epidemiological situation remains unfavorable south European part Russia. In addition annual patients identification, demonstrable trend shifting expansion pathogen’s area northerly direction was established. It creates risk spread virus outside southern regions country. High incidence dangerous vector-borne infection — West Nile with involvement new subjects emergence local previously non-endemic territories registered. Expansion renal syndrome foci borders, zoonosis etiology Federation second by identification after infections, noted. Research data dependence carriers number dynamics values factors, confirmed using various methods mathematical statistics (time-series analysis, autoregression integrated moving average, logistic regression, correlation one-way variance other) were systematized. found that temperature humidity air soil, amount precipitation, height snow cover common abiotic all investigated infections. The these can be used subsequent forecast. further study relationship between rate population, arthropod small mammals indicators soil moisture at different depths, hydrothermal coefficient, normalized relative vegetation index, accumulated as well similar studies other actual will very promising.
