Overview This dataset contains the temporal network of contacts between patients, between patients and healthcare workers (HCWs), and among HCWs in a hospital ward in Lyon, France, from Monday, December 6, 2010, at 1:00 pm to Friday, December 10, 2010, at 2:00 pm. The study included 46 HCWs and 29 patients. Timestamps were recorded in 20-second intervals. In the original data, each line has the form "t i j Si Sj", where i and j are the anonymous IDs of the persons in contact, Si and Sj are their labels (NUR=paramedical staff, i.e. nurses and nurses' aides; PAT=Patient; MED=Medical doctor; ADM=administrative staff), and the interval during which this contact was active is [ t – 20s, t ]. We form hyperedges through cliques of simultaneous contacts. Specifically, for every unique timestamp in the dataset, we construct a hyperedge for every maximal clique amongst the contact edges that exist for that timestamp. All timestamps are in standard ISO8601 format. Statistics number of nodes: 75 (46 HCWs and 29 patients) number of timestamped hyperedges: 21,398 there is a single connected component of size 75 Changelog v0.1: Updated format to HIF Source of original data Hospital ward dynamic contact network References If you use this dataset, please cite the following: Estimating Potential Infection Transmission Routes in Hospital Wards Using Wearable Proximity Sensors.
