Abstract

As a result of social and economic transformation taking place in the Russian Federation over the last 20 years the number of urban inhabitants has been steadily elevating. Urban areas are increasing. Cities absorb not only the surrounding communities, but also the non-urban fauna and flora, and with them the natural foci of certain feral herd infectious (FHI) diseases. The study found that the results confirm the existence of the necessary conditions for the formation and operation of natural foci in the metropolis - Ulyanovsk. 3 out of the 4 infections mentioned above: leptospiroses (39.2%), followed by Hemorrhagic fever with renal syndrome (HFRS) (17,9%) and Ixodes tick-borne borreliosis (ITB) (14,7%) obtained a wide dissemination. In such separate territories of the region center as Park Pobedy, Belyy Klyuch», Park Karamzina, park «Yunost'» the existence of conjugate foci of the FHI (HFRS, Tick-borne viral encephalitis (TVE), leptospirosis) has been proved.
