Q fever due to Coxiella burnetii is a zoonotic disease affecting ruminants worldwide. Although large outbreaks in human have been also reported, usually linked to infected livestock, several aspects of the pathogen dynamics in the affected animal populations are yet to be elucidated, including its spatial distribution, prerequisite to identify the strength of the association with epidemiological factors that could promote or prevent disease spread and transmission. Here, the distribution of C. burnetii seropositive cattle herds has been assessed in the region of Madrid, Spain, using the Cuzick-and-Edwards test and the spatial scan statistic. Strong spatial dependence was identified at the first level of neighborhood using the Cuzick-and-Edwards`s test. However, no local cluster was identified using the spatial scan statistic. These findings are likely to be associated with a relatively simple dynamics for disease transmission at the local level throughout the entire region, rather than at particular areas at high risk
