Journal Title: Актуальна інфектологія - Year 2015, Vol 4, Issue 9
Abstract
Introduction. In the Orenburg region, as well as in the Russian Federation as a whole, hemorrhagic fever with renal syndrome caused by Puumala virus occupies a leading position among the natural focal diseases. The objective of research — to identify the epidemiological features of the epidemic hemorrhagic fever with renal syndrome among the population of the Orenburg region in comparison with the manifestations of the epidemic process of this infection in the other areas of the region. Materials and methods. We have studied the morbidity in the Orenburg district of the Orenburg region, which is the territory of stationing of some military units. The incidence was analyzed according to the data of Federal Service for Surveillance on Consumer Rights Protection and Human Wellbeing for the 1970–2014. Results. Since 1997, it showed a trend toward a decrease of morbidity in the region. The beginning of the epidemic year in September was determined. 7 areas were identified as areas of risk. We have noted the unfavorable epidemiological situation in neighboring (Perevolotsk) region. The tendency towards stabilization of morbidity in the Orenburg region and the close correlation between the morbidity of the population of Orenburg and Perevolotsk areas was shown. Discussion. The differences of seasonality in the Orenburg region from that of in Russia as a whole are due to landscape features. Orenburg and Perevolotsk areas with steppe landscape are characterized by the development of the epidemic process in similar conditions. The upward trend in morbidity of the population of Perevolotsk district is alarming harbinger of the epidemiological situation in the Orenburg region, where today the epidemiological situation is safe. 2015 should be considered as a year of stabilization or a year of the incidence decrease. Conclusion. There was determined the heterogeneity of the Orenburg region in terms of the level and long-term trend of morbidity. Orenburg district is not a risk area. Seasonal manifestations in the region are characterized by parameters specific to the forest steppe and steppe landscapes.
