Q fever is a zoonosis. Humans are infected through the inhalation of Coxiella burnetii particles that are dispersed into the air from the birth products or faeces of ruminants. Major outbreaks can occur in association with farming activities. C. burnetii can be disseminated by wind up to several tens of kilometres and infect humans far from its zoonotic source. As a result, the sources of sporadic cases are rarely identified. We report a sporadic case of acute Q fever in a French farmer returning from a cruise in the Caribbean. Careful examination found that the infection was not associated with travel, and a veterinary investigation identified C. burnetii DNA (MST genotype 8) in the faeces, nasal and vaginal swabs of several ewes from her herd of sheep. As a consequence, the herd was slaughtered to avoid dissemination of the infection.

零星的急性Q发热病例，并确定了感染的动物来源。

Q发烧是人畜共患病。人体通过吸入燃烧的柯氏杆菌颗粒而被感染，该颗粒从反刍动物的出生产物或粪便中散布到空气中。与农耕活动有关的地方可能发生重大疫情。伯氏梭状芽胞杆菌可通过长达数十公里的风传播，并从远离人畜共患源的地方感染人类。结果，很少发现零星病例的来源。我们报告了从加勒比海游船返回的一名法国农民零星发生的急性Q发热病例。仔细检查发现感染与旅行无关，兽医检查发现羊群中几只母羊的粪便，鼻和阴道拭子中存在伯氏梭菌DNA（MST基因型8）。结果，牛群被宰杀以避免传播感染。
