We describe an important Q fever human epidemic involving 415 serologically confirmed cases in the Val de Bagnes (Valais, Switzerland) during the autumn of 1983. The ages of the 415 cases with acute Q fever ranged from 8 to 82 years with a mean of 35 years, of whom 58% (240) were men and 42% (175) were women. This outbreak started about three weeks after 12 flocks of sheep (between 850 and 900 animals) descended from the alpine pastures to the valley. Geographically, the epidemic reached all the villages in the lower part of the Val de Bagnes located along the road followed by the sheep. As a result, 21.1% of the population of these villages contracted Q fever during this period. In contrast (p less than 0.001), the inhabitants of the higher villages away from the road followed by the sheep were only slightly affected (2.9%). Better collaboration between physicians and veterinarians would prevent such outbreaks in the future.
我们描述了1983年秋季在瑞士瓦莱州巴涅谷地发生的一起重要的人Q热疫情，有415例血清学确诊病例。415例急性Q热病例的年龄在8岁至82岁之间，平均年龄为35岁，其中58%（240例）为男性，42%（175例）为女性。此次疫情在12群绵羊（850至900只）从高山牧场下到山谷大约三周后开始。从地理范围来看，疫情蔓延到了巴涅谷地下游沿绵羊经过道路分布的所有村庄。结果，这些村庄21.1%的人口在此期间感染了Q热。相比之下（p<0.001），远离绵羊经过道路的上游村庄居民仅受到轻微影响（2.9%）。医生和兽医之间更好的合作将预防未来此类疫情的发生。
