Abstract
Tick-borne encephalitis and Lyme disease are the most widespread natural focal neuroinfections in the Russian Federation. The analysis of clinical and epidemiological data on 1421 cases of tick-borne encephalitis and Lyme disease (782 and 639, respectively) in the Republic of Bashkortostan from 2000 to 2023 was carried out. The clinical picture of 47 cases of focal tick-borne encephalitis and borreliosis of the nervous system (neuroborreliosis) is considered according to the analysis of 200 cases of acute Lyme disease. Most cases of tick-borne encephalitis infections are observed in the climatic and geographical zone of the Southern Urals of the Republic of Bashkortostan. The average long–term incidence of tick-borne encephalitis was 0.9 ± 0.5 cases, Lyme disease - 0.8± 0.4 per 100 thousand population. Focal forms of tick-borne encephalitis in the Republic of Bashkortostan in the 2000s were found in 6.0 ± 5.1% of patients. The neuroborreliosis clinic in 10 patients (5.5%) was characterized by the phenomena of monoradiculoneuropathy of various localization, sensory polyneuropathy, neuritis of the facial nerve, trigeminal nerve damage and meningeal syndrome. Thus, the Republic of Bashkortostan in the current 2000s is an area with an average level of epidemic danger for tick-borne encephalitis and a low level of epidemic danger for Lyme disease. The clinic of focal forms of tick-borne encephalitis manifests itself in the whole spectrum of possible neurological syndromes, up to the most severe with fatal outcome. The clinical picture of neuroborreliosis is characterized mainly by symptoms of damage to the peripheral nervous system.
