Before revision:  Finally, we use "face-to-face" experiments to generate a more accurate distribution of normalized contact times, and we repeat the analysis for this distribution  .
After revision:  Finally, we use "face-to-face" experiments to generate a more accurate distribution of normalized contact times, and we repeat the analysis for this distribution _1 = T_c / \beta below which the strategy can bring the system from an epidemic to a non-epidemic phase, even when close contacts have the longest time durations .
