Figure 2. (A) Distribution of contact durations: Estimated kernel density from the empirical distribution of contact durations, by contact pair type. For this plot, only contacts between 6 am and 8 pm, and durations between 1 minute and 5 hours were considered. Both x-axis and y-axis are on the log scale; (B) distribution of time spent close to a static sensor: Estimated kernel density from the empirical distribution of time spent close to a static sensor, averaged over all individuals, during the study period. The x-axis is on the log scale.
