Although recent reports of Tick-borne encephalitis (TBE) in Croatia belie the fact that this disease has been steadily declining for five decades, the impact of TBE in Croatia is comparable to that of the main form of arthropod-borne encephalitis in the United States. See graph
TBE was first reported in Croatia in 1953, and mandatory reporting was instituted in 1987. There is only one natural focus in the northern part of the country, between the Sava and Drava Rivers. Alleged cases in Zadar and Pula, have not been certified. 75% of cases occur from May to July.
Approximately 20 cases per year are reported in Koprivnica-Krizevci County, characterized by a relatively mild illness without neurological residua.
