These cases were reported mostly from patients in the districts of Beroun (Central Bohemia), Hradec Kr\u00e1lov\u00e9 (East Bohemia), Vy\u0161kov (South Moravia), and occasionally from the neighborhood of Prague. The official reports of these probable cases of \u201dtick-borne encephalitis\u201d were registered in the database of the National Institute of Public Health in Prague since 1945. The first TBEV isolation was accomplished from blood and cerebrospinal fluid of a patient with meningoencephalitis. Other successful isolations were from subjects with a history of a tick bite. The first successful attempt of isolation of the TBE virus from different developmental stages of I. ricinus ticks, collected in forests of the district Beroun, was in 1949. The analysis of an outbreak of meningoencephalitis in Ro\u017e\u0148ava in south-eastern Slovakia in 1951 from Czech and Slovak specialists ended with the discovery of the alimentary transmission of the TBE virus. The definition of TBE for reporting changed in the following decades. Following a ministerial decree from 1970, only clinically-manifested, laboratory-confirmed cases of TBE were to be reported to the central surveillance center. The number of case characteristics collected from TBE patients has gradually increased ever since 1982. Since 1993, the national reporting system (EPIDAT) has been computerized. TBE surveillance was established by Regulation No. 275\/2010, Annex No. 28. The Czech Republic is a highly TBE endemic country. Many cases are associated with outdoor activities (camping, living in secondary residences in the countryside, hiking, hunting, fishing, mushrooming), while the incidence of occupational transmission has decreased over the last years (in 2022: 20 cases, i.e., 2.8% among foresters and farmers). Numbers of imported cases from abroad are very low with only 1 case (0.2%) in 2021 and 5 cases (0.7%) in 2022. The geographical distribution of TBE is changing. The gradual spread of TBE into formerly unaffected districts, namely into the border districts of the country at higher altitudes is highlighted. Long-term observations confirm a shift of age-specific incidence rates to older age groups. The period of the transmission of TBE is changing too. The \u201cTBE-season\u201d with detection of cases is longer than 30\u201350 years ago and lasts from March to December. These changes of basic epidemiological characteristics may be due to climatic changes, changes of environmental and\/or other factors. These factors are affecting the different interactions between TBEV, its vectors and vertebrate hosts too. Vaccine uptake is very low, the highest rate is reached in the age group of 18\u201324-year-olds, the lowest among children younger than 4 years; however, there is no central vaccination registry. Data from 8 international telephone surveys in 2009, 2013, 2015, 2018, 2019, 2020, 2021, and 2022 which covered the whole Czech population and defined a \u201cvaccinated person\u201d as someone having received \u22651 dose vaccine uptake, was estimated to be 16, 23, 24, 25, 29, 33, 33 and 38%, respectively. Unpublished data from some Czech regions indicate that vaccine uptake with \u22653 doses is even lower.
