“…This viral non-transmissive zoonosis in Russia is leading among zoonotic viral infections and takes almost the first place among all natural human focal diseases. During several years the number of the registered cases reaches 20,000 and more [5,6]. Rodents are HFRS infection source, and the virus does not have a pronounced monohostality, so many local rodent fauna can become dangerous.…”

The research deals with the assessment of the epidemiological and epizootic situation in the Vladimir region, concerning natural focal infections in the context of agricultural activities. The retrospective analysis of statistical data on morbidity anthropozoonoses taken from the Report forms №2 “Information on infectious and parasitic diseases” FBUZ “Hygiene and Epidemiology Center in Vladimir region” of Rospotrebnadzor Department of the Vladimir region during the period of 1958 – 2016. The study of the biological material in respect of pathogen the natural focal infections were conducted in the laboratory of natural-focal and especially dangerous infections FBUZ “Hygiene and Epidemiology Center in Vladimir region” Rospotrebnadzor Department of the Vladimir region. The following natural-focal diseases have been stated to be registered as important in the context of agriculture in the Vladimir region: hemorrhagic fever with renal syndrome (HFRS), leptospirosis and tularemia. HFRS domonates in the morbidity structure. Annual laboratory tests of the biological material regarding the pathogens of natural focal infections indicate the presence of epizootics among mouse-like rodents, red vole (M. glareolus) being the dominant species among them. The ratio of HFRS male to female is approximately 3 to 1 Positive results of the laboratory studies indicate epizootic activity and constant risk of exacerbation of the epidemic situation regarding zooanthroponotic infections, and zero human morbidity during a number of years does not speak of the attenuation of the natural infection focus and the basis for stopping the preventive measures.

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

The features of clinical and laboratory diagnostics of hantavirus infection at the prehospital stage in the regions of the Northwestern Federal District is considered. The analysis of the terms of patients treatment from the moment of the appearance of the first symptoms of the disease was carried out. It was found that more than half of the patients sought a medical help during the height of the disease. The structure of hospitalizations of the patients with a hemorrhagic fever with renal syndrome who were admitted to inpatient treatment was studied; most patients were hospitalized by the ambulance team. The data of our own research are presented, indicating the predominance of the nonspecific symptoms in the onset of the disease. The overwhelming majority of the patients in the initial period of the disease had fever, severe headache, myalgia. Hemorrhagic syndrome was detected in a minimal number of the patients. The dynamics of the clinical picture of a hemorrhagic fever with the renal syndrome in patients admitted to hospitals in St. Petersburg was analyzed. Diversity and a rapid change of the symptoms and syndromes in dynamics were noted. In the structure of diagnoses of the direction, diseases of the respiratory system prevailed. A smaller proportion of a preliminary diagnoses were diseases of the gastrointestinal tract, pathology of the kidneys and urinary tract, diseases of the central nervous system, and only one patient was diagnosed with the hemorrhagic fever with renal syndrome. The laboratory parameters of the early period of the disease in patients were assessed. The most frequent and characteristic changes in the blood and urine parameters were revealed. Signs of hemoconcentration and thrombocytopenia were noted in almost half of the patients in the initial period of the disease. In a small part of outpatients, impaired renal nitrogen excretory function was found; the intensity of azotemia in the initial period of the diseases was low. Urine changes in the initial period were characterized by the moderate proteinuria, leukocyturia, erythrocyturia, cylindruria. The need for a thorough comparison of a clinical, laboratory, epidemiological data for a timely and correct diagnosis is noted.
