The aim of this review is to follow the history of studies on endemiv arboviruses and the diseases they cause which were detected in the Czech lands (Bohemia, Moravia and Silesia (i.e., the Czech Republic)). The viruses involve tick-borne encephalitis, West Nile and Usutu flaviviruses; the Sindbis alphavirus; Ťahyňa, Batai, Lednice and Sedlec bunyaviruses; the Uukuniemi phlebovirus; and the Tribeč orbivirus. Arboviruses temporarily imported from abroad to the Czech Republic have been omitted. This brief historical review includes a bibliography of all relevant papers.

UNLABELLED: This study of 170 children in the Czech Republic examines the clinical course and sequelae for tick-borne encephalitis. Evaluated were demographic and epidemiological data, signs and symptoms at admission, clinical course during hospital stay and laboratory findings. Cerebrospinal fluid was analysed for white blood cells, protein, impairment of blood-cerebrospinal fluid (CSF) barrier and tick-borne encephalitis virus (TBEV)-specific antibodies. Subjective complaints and objective neurological deficits were investigated. Tick bites were reported in 74 % of the children. The illness had a biphasic clinical course in 58 % of cases. The second phase was characterized by headache in 98 %, high fever in 86 % (more than 38.5 °C), vomiting in 64 % and meningeal signs in 92 % of children. Meningitis (77 %) dominated over meningoencephalitis (13 %). Inflammatory changes in CSF were found in 90 % of children. Immunoglobulin M (IgM) antibodies against TBEV in serum were found early in the infection in 99 %. IgM positivity lasted up to 1,126 days. Neurocognitive abnormalities were found in 19 (11 %) of children. Acquired aphasia, lasting tremor of the upper extremities, speech impairment, inversion of sleep and wakefulness, abnormal hyperkinetic movements and vertigo were found to be permanent but not progressing. Severe sequelae persisted in two children (1 %) while in three (2 %) were classified as mild or moderate. CONCLUSION: Tick-borne encephalitis in children has a benign course with minimal sequelae. Meningitis with biphasic course is the prevalent involvement and the duration of IgM antibodies in serum and index of positivity are not decisive for postencephalitic disorders.

BACKGROUND: The Czech Republic ranks among the countries with the highest prevalence of tick-borne encephalitis worldwide. The region of West Bohemia has the second highest morbidity within the Czech Republic. METHODS: Between 1960 and 2007, laboratories confirmed 410 cases of tick-borne encephalitis in children and adolescents of West Bohemia. Available epidemiological data were analyzed. RESULTS: The highest incidence (per 100 000 population) was found in the group of 15-19 years for both genders (males: 6.2; females: 4.3). Data on the consumption of non-pasteurized milk were found in 5.4% of patients. The preschool age group showed its highest incidence in June and September, and the risk of infection for older children was in July and August. CONCLUSIONS: The current low coverage of vaccination leads to an insignificant improvement to the overall frequency of this disease.
