Between 2009 and 2012, slightly more than 10% (n = 193) of towns in the study area were involved in at least one consolidated cluster (Table 3). Repeated clusters occurred in only 14% of the positive towns (with at least one cluster during the 4-year study period), and in only 1.5% of all towns. The maximum number of repetitions was four consolidated clusters for one town.
