Contact network of health-care workers. a Visualization of the contact network of HCWs, aggregated over the whole data collection. Each node represents a HCW (the number stands for the RFID number, the color for the category as indicated in the color code). A link between two nodes exists if at least one contact between the corresponding HCWs was detected, and the link thickness gives the aggregate duration of contacts. The size of each node is given by its degree (number of links). b Cumulative duration (blue bars) of the contacts of each HCW, and number (green) of distinct other HCWs met by each HCW, during the whole data collection. These quantities correspond respectively to the strength and the degree of each node in the network of a. c Contact patterns of a specific HCW along several days. Each bar gives, for each hour of the day, the cumulative duration of contacts between HCW 113 (housekeeping staff) and other HCWs identified each by a specific color.
