Chapter 12b: TBE in Poland


           Table 2: TBE reporting and vaccine prevention in Poland
                          ONLY cases of neuroinfection
                          Case definition—per ECDC (2.44) 19

                          Clinical Criteria: Any person with symptoms of inflammation of the central nervous
                          system (CNS): e.g. meningitis, meningoencephalitis, encephalomyelitis, encephalo-
                          radiculitis.

                          Laboratory Criteria: Laboratory criteria for case confirmation
                          At least 1 of the following 5 criteria:
                           TBE-specific IgM AND IgG antibodies in blood
                           TBE-specific IgM antibodies in cerebrospinal fluid (CSF)
                           Seroconversion or 4-fold increase of TBE-specific antibodies in paired serum samples
                           Detection of TBE viral nucleic acid in a clinical specimen
          Mandatory TBE    Isolation of TBEV from clinical specimen
          reporting
                          Laboratory criteria for a probable case:
                           Detection of TBE-specific IgM-antibodies in a unique serum sample
                           Serological results should be interpreted according to the vaccination status and
                            previous exposure to other flaviviral infections. Confirmed cases in such situations
                            should be validated by serum neutralization assay or other equivalent assays

                          Epidemiological Criteria: Exposure to a common source (unpasteurized dairy products)

                          Case Classification
                           Probable case: Any person meeting the clinical and laboratory criteria for a probable
                            case; any person meeting the clinical criteria and with an epidemiological link
                           Confirmed case: Any person meeting the clinical and laboratory criteria for case
                            confirmation
          Other TBE       Obligatory reporting by diagnostic laboratory of any positive results from serological (IgM)
          surveillance    examination to local health service in the patient’s place of residence
          Special clinical   Contact with ticks; consumption of non-pasteurized dairy products 14,15

          features        Mortality 0.5-2.8%
                          Since 1993:
                            FSME-Immun (manufacturer: Pfizer) in 2 formulations
          Available vaccines   (adults and children <16 years of age)
                            Encepur (manufacturer: GSK) in 2 formulations
                            (for adults and children 1-11 years of age).

          *In Poland, vaccination against TBE is recommended (but not financed from the budget of the Ministry of Health) for persons
          in areas with severe occurrence of the disease, in particular: forest workers, foragers (e.g. persons who harvest mushrooms,
          berries, etc – commercially or recreationally), stationed military, guards brigade and border, farmers, young people in practice
          (outdoor play and recreation), tourists and visitors to camps and colonies.
