Simultaneous space-time clusters of Campylobacter spp. in humans and broilers. Geographical location of simultaneous space-time clusters of human campylobacteriosis cases and broiler flocks positive for Campylobacter spp. each year 2002-2007 in Norway. Clusters were identified by the multivariate SaTScan™ Poisson model. The shaded areas indicate the study area during different years (municipalities with broiler farms). The clusters are ranked according to their likelihood ratio test statistic.
