Q fever is a zoonosis caused by Coxiella burnetii, and transmission to humans is often associated with contact with ovine and caprine livestock. Those exposed to sheep are particularly at high risk of infection. Recent studies show that Q fever is increasing in sheep farms in Portugal raising alerts on spillover to humans. We detected anti-C. burnetii IgG in shepherds and sheep milk cheesemakers (27 [28.1%] in a total of 96; 95% confidence interval [CI] 19.4–38.2%) and in controls (21 [8.1%] in a total of 260; 95% CI 5.1–12.1%), pointing to an increased risk of C. burnetii infection (P = 0.0001), with an odds ratio for anti-C. burnetii of 4.45 (95% CI 2.4–8.4%; P = 0.0001), in individuals with occupational contact with sheep in Portugal.

在牧羊人和羊奶奶酪制造者中职业性地获得了Q发烧。

Q热是由伯氏柯氏杆菌引起的人畜共患病，而传播给人类通常与绵羊和山羊牲畜接触有关。那些暴露于绵羊的人特别容易受到感染。最近的研究表明，葡萄牙养羊场的Q热正在增加，引起人们向人类溢出的警报。我们检测抗贝氏柯克斯的IgG在牧羊人和绵羊奶奶酪（27 [28.1％]在总共96; 95％置信区间[CI] 19.4-38.2％）总共和对照组（21 [8.1％]的260; 95％CI 5.1-12.1％），指向的风险增加贝氏柯克斯感染（P  = 0.0001），与比值比为抗-C。Burnetii为4.45（95％CI 2.4–8.4％；P = 0.0001），在葡萄牙与绵羊有职业接触的人。
