title: [Epidemiology of Ixodes tick-borne borreliosis in the north of the Volga-Viatka region].
abstract: Among the territories of the Volga-Vyatka Region of Russia, the Kirov Region is characterized by the highest incidence of Ixodes tick-borne borreliosis. Its incidence rates ranged from 10.5 to 48.6 per 100,000 inhabitants. The average long-term regional rate was 8 times as high as the federal one. The bulk of cases was notified in the central regional districts referred to as a southern taiga subarea. The infection with the borreliae I. persulcatus and I. ricinus was 21-29%. Urban inhabitants infected for domestic reasons were prevalent among those who had been ill. Patients aged above 40 years accounted for 64.5%. There was an increase in the proportion of patients referring for medical care for the bites being stuck. Cases of mixed infections (Ixodes tick-borne borreliosis and tick-borne encephalitis) came to be more frequently detected; these constituted about a third of all tick-borne infections.
