Spatial clustering of infection probability in the Finistère department. Seven statistically significant spatial clusters (circled in red) with high relative risk (values are indicated in the legend) of presence of predicted incident herds (red dots), initially susceptible and infected by C. burnetii after one year of inter-herd spread. The positivity of a herd was defined based on a cut-off value of 0.25 for the probability of infection. Herds initially seroprevalent according to the data (orange dots) and herds which remain uninfected (green dots) are also represented.
