Q fever as one of infections with natural foci is characterized by epidemic outbreaks. Biologic plasticity and ecologic peculiarities of Coxiella determine its wide distribution and development of Q fever infections which are disseminated almost every-where. They occur in two, i. e. natural and agricultural types of foci. Present paper characterizes their structures, maintenance and peculiarities if their existence. It should be emphasized that single cases of disease as well as outbreaks of Q fever originate usually from agricultural foci, where the source of the infection are livestock, sheep and goats. Data are presented on the involvement of these animals into circulation of coxiellae in various countries of the world. It was shown that agricultural foci of Q fever depending upon close connection with domestic animals are determined in many aspects by basic factors of an epidemic process of the infection, i. e. seasonal occurrence, social conditions, professional relations, etc. which also enhance the course of the infection. Principles on prophylaxis complete the given paper.
Q热作为一种自然疫源性感染，其特点是会出现流行暴发。柯克斯体的生物学可塑性和生态学特性决定了它的广泛分布以及Q热感染的发展，这种感染几乎在各地都有传播。它们出现在两种类型的疫源地，即自然疫源地和农业疫源地。本文描述了它们的结构、维持情况以及存在的特点。需要强调的是，Q热的散发病例以及暴发通常源于农业疫源地，在那里，感染源是家畜、绵羊和山羊。文中给出了关于世界各国这些动物参与柯克斯体传播的数据。结果表明，Q热的农业疫源地由于与家畜的密切联系，在很多方面由感染流行过程的基本因素决定，比如季节性出现、社会条件、职业关系等，这些因素也会加重感染进程。预防原则完善了本文。
