title: [Epidemiological characterization of Ixodes tick-borne borreliosis in the Krasnoyarsk territory].
abstract: The analysis of morbidity in tick-borne infections for many years indicates that in the 1960s-1990s in the total structure of the clinical forms of tick-borne encephalitis the erythematic form amounted to 1.4-20.9, which 1.9- to 3.1-fold exceeded the morbidity characteristics for the whole of Russia. The epidemiological analysis of morbidity at the territory for the period of 1992-2001 is indicative of the presence of the combined foci of tick-borne encephalitis and Ixodes tick-born borrelioses (TBB) in 42 regions of the territory. The cyclic character of morbidity and the irregularity of its spread in different regions of the territory can be observed. Among the TBB patients, town dwellers constitute, on the average, 75.8%. These tick-born infections exhibit regional differences connected with landscape variations and the patients age. However official statistics does not reflect the real epidemic situation at the territory: hypodiagnostics is primarily due to the absence of reliable laboratory confirmation in remote regions of the Krasnoyarsk territory.
