The temporal and spatial transmission map with three potential risks for C. difficile NAP1/BI/027 spreading. The transmission connections in two consecutive years were marked using blue and red lines, respectively. The full lines represent the potential transfer route with both genomics and epidemic evidence, and dashed lines connected the patients among whom only have potential genetic links. ”?” represented the unknown nodes during the transmission and evolution. The architectural structure, room arrangement, and distribution of NAP1/BI/027 cases in this ward were displayed at the bottom. Patients during the two outbreaks are distinguished by different colors of background: red for those in 2012 and blue for those in 2013 to 2014
