“…The epidemiology of TBE comprises geographical distribution, age aspects, the influence of landscape, agricultural activities, leisure time activities, migration and travel of populations as well as political and climate changes occurring in the respective region . The total number of annual cases is estimated to be up to 13 000 in the Eurasian northern hemisphere where this zoonotic flavivirus infection constitutes the most important tick‐borne viral disease .…”

“…A considerable increase in TBE morbidity has been observed in Europe over the decades, but different developments with fluctuations including periodical decreases of cases in some countries have been reported in recent years. However, a tendency for increase of areas and prolongation of the season has occurred across large endemic regions of Europe and Asia . The risk of TBE is related to occupational exposure, outdoor leisure activities and travelling from non‐endemic to endemic regions.…”

“…Three subtypes of TBEV with different phylogenetic and pathogenic characteristics have been distinguished, the Western subtype (W-TBEV), the Siberian subtype (S-TBEV), and the Far-Eastern subtype (FE-TBEV) (3). In the past decade Europe has suffered an increase of tick-borne encephalitis (TBE), which can cause a disease of the central nervous system (4). In the unvaccinated population of Austria, a total of 8,493 cases of TBE have been reported from 1972 to 2011, with an average incidence rate of about 6 cases per 100,000 population (5).…”

“…The virus is transmitted to susceptible individuals through tick bites or consumption of unpasteurized milk from recently infected animals [1]. TBE is restricted to geographical areas referred to as endemic foci [1,2]. Factors influencing survival of ticks, large mammals and transmission-competent rodents may explain the distribution of these foci and their changes over time [3,4].…”

New endemic foci of tick-borne encephalitis (TBE) identified in districts where testing for TBE was not available before 2009 in Poland

BackgroundTick-borne encephalitis (TBE) is found in limited endemic foci in Poland. Lack of diagnosis limits disease detection in non-endemic provinces.MethodsIn 2009, we enhanced TBE surveillance to confirm the location of endemic foci and inform vaccination policy. In 105 hospitals located in 11/16 provinces, we identified suspected TBE cases through admission ICD-10 codes indicating aseptic meningo-encephalitis or from specimens tested for TBE. The National Reference Laboratory confirmed cases at no cost, by testing serum and/or cerebrospinal fluid using ELISA method. We calculated TBE reported rates as the number of confirmed TBE cases per 100,000 inhabitants. Adjusting to neighbouring districts, we classified districts as non-endemic (<0.1 cases per 100,000 inhabitants), low endemic (> = 0.1 to <1), moderately endemic (> = 1 to <5) and highly endemic (> = 5). We compared surveillance data obtained in 2009 with 2004–2008 baseline data.ResultsAmong 166,099 admissions, we identified 1,585 suspected TBE cases of which 256 were confirmed. Physicians reported more suspected cases among patients <40 years old (12 cases per 1,000 admissions) than among older patients (8 cases per 1,000 admissions). However, patients <40 years of age were confirmed less frequently (16%), than older patients (35%). Physicians reported more suspected cases in districts classed as endemic during 2004–2008 (12 cases per 1,000 admissions, 77% tested for TBE) than in districts classed as non-endemic (7 cases per 1,000 admissions, 59% tested). Of the 38 newly identified endemic districts, 31 were adjacent to 2004–2008 endemic districts and 7 were isolated.ConclusionsEnhanced surveillance detected 38 new endemic districts to be considered for TBE vaccination. However, lack of consistent testing in districts believed to be TBE-free remained an obstacle for mapping TBE risk. Although the disease affects mostly older adults and the elderly, more attention is given to the diagnosis of TBE in young patients. Solutions need to be identified to sustain sensitive, acceptable and affordable TBE surveillance in all districts of Poland. Also, higher attention should be given to the diagnosis of TBE in the elderly.
