Kaplan-Meier survival functions showing time to detection of first three cases; according to different sample sizes calculated for 1% (a), 2% (b) and 5% (c) design prevalence, and stratified by surveillance strategies. HC: high consequence, HR: high risk, HR/HC: high risk- high consequence. Only simulations with at least three infected sites were eligible for this outcome
