In most locations except for Russia, tick-borne encephalitis is mainly caused by the European virus subtype. In 2015, fatal infections caused by European and Siberian tick-borne encephalitis virus subtypes in the same Ixodes ricinus tick focus in Finland raised concern over further spread of the Siberian subtype among widespread tick species.
在俄罗斯以外的大多数地区,蜱传脑炎主要由欧洲病毒亚型引起。2015 年,在芬兰的同一个硬蜱媒介中,欧洲和西伯利亚蜱传脑炎病毒亚型引起的致命感染引起了人们对西伯利亚亚型在广泛分布的蜱种中进一步传播的关注。
