Fig. 2From: Mathematical modelling of vancomycin-resistant enterococci transmission during passive surveillance and active surveillance with contact isolation highlights the need to identify and address the source of acquisitionVRE transmission model. U = the number of patients who were not known to be colonised/infected (i.e. uncolonised); C = the number of patients colonised/infected and not detected (and therefore not contact isolated); D = the number of patients who were detected (observed as VRE colonised/infected) and contact isolated; αU, αC and αD are the admission rates for U, C and D patients, respectively, and μU, μC and μD are the discharge rates for U, C and D patients, respectively. Pr U → C = probability of VRE colonisation or infection in uncolonised patients. The detection probability (λ) is expressed as the probability of being detected given that a patient is VRE colonised/infectedBack to article page
