Tick-borne encephalitis (TBE, in French MEVE) is a viral disease usually transmitted to man through an infected tick belonging to the genus Ixodes. Every year about 135 cases of TBE are reported to the Swiss Federal Office of Public Health. Emerging in north-east of Switzerland in the seventies, endemic areas have been slowly spreading. Actually 18 cantons out of 26 have been reached. In the western part of Switzerland, spared until not long ago, new endemic foci are spreading toward the lake of Geneva and recently in Valais. The precise exposure history of human cases, as well as the evaluation of collected tick samples allow the detection of endemic foci which are discontinuous and of variable size. New and more efficient methods are needed to monitor the changing epidemiology of TBE.
蜱传脑炎（TBE，法语为MEVE）是一种病毒性疾病，通常通过感染的硬蜱属蜱虫传播给人类。每年约有135例蜱传脑炎病例报告给瑞士联邦公共卫生局。该病于70年代在瑞士东北部出现，流行地区一直在缓慢蔓延。实际上，已经蔓延到了26个州中的18个。在瑞士西部，直到不久前还未受影响，现在新的流行病灶正朝着日内瓦湖蔓延，最近在瓦莱州也出现了。通过了解人类病例的精确暴露史以及对采集的蜱虫样本进行评估，可以发现不连续且大小各异的流行病灶。需要新的更有效的方法来监测蜱传脑炎不断变化的流行病学情况。
