Permutation test results by random walk modeling for incidents 1 (a-d) and 2 (e-h). a The observed number of 19 cases in incident 1 was unlikely to be due to pure waterborne infections. b-d Simulated number of cases by different probability of interpersonal transmission from 1000 experiments. e The observed number of 12 cases in incident 2 was unlikely to be due to random infections. f-h Simulated number of cases by different relative visit frequency intensity from 1000 experiments
