Networks of HCWs contacts informed by the hand-hygiene compliance data. In each network, similarly to Fig. 2 a, nodes represent HCWs, with a different color according to each HCW’s category, and a link between two nodes indicates that the corresponding HCWs have been in contact at least once. Here only contacts for which at least one of the HCWs was monitored by the MediHandTrace (MHT) infrastructure, and occurring after at least one of the HCWs involved had a contact with a patient, are taken into account. We create two contact networks by integrating the information about hand-hygiene compliance of HCWs: the network of green links corresponds to contacts in which HCWs monitored by MHT have used HAS before the contact; the network of red links corresponds to contacts occurring after at least one of the HCWs had a contact with a patient and did not use HAS afterwards. In each network, the links thickness depends on the aggregate duration of contacts. a Networks aggregated over the whole data collection; b two examples of daily contact networks.
