The first tick-borne encephalitis (TBE) cases in Kotka, Finland appeared in 2010. Altogether ten human cases have been diagnosed by 2014. Four had long-lasting sequelae. We collected 195 Ixodes ricinus ticks, nine rodents, and eleven shrews from the archipelago of Kotka in 2011. Three Siberian subtype TBE virus (TBEV) strains were isolated from the ticks and three mammals were positive for TBEV antibodies. The archipelago of Kotka is a newly emerged TBE focus of Siberian subtype TBEV circulating notably in I. ricinus. The patients had on average longer hospitalization than reported for the European subtype infection.
芬兰科特卡的首例蜱传脑炎（TBE）病例于2010年出现。到2014年，共诊断出10例人类病例。其中4例有长期后遗症。2011年，我们从科特卡群岛采集了195只蓖麻硬蜱、9只啮齿动物和11只鼩鼱。从蜱中分离出3株西伯利亚亚型TBE病毒（TBEV）毒株，3只哺乳动物TBEV抗体呈阳性。科特卡群岛是一个新出现的西伯利亚亚型TBEV的TBE疫源地，该病毒在蓖麻硬蜱中尤为流行。与欧洲亚型感染的报告相比，这些患者的平均住院时间更长。
