  1. Sampled data for three different transmission assumptions and five levels of HHC for one colonised nurse starting in a random room in the hospital ward, a hand hygiene efficacy (γ) of 0.83. P= probability of transmission, λ= HHC level, RO1= amount of time spent colonised, RO2= number of contact moments, RO3= number of HCWs or patients made contact with, RO4= number of transitions between hospital ward rooms, RO5= expected number of HMO transmissions
