Figure 4

Effect of the patient isolation efficacy when combined with biannual decolonization of health care workers. The two graphs correspond to scenarios with minimum effect of decolonization of HCWs (A) (10% of the HCWs are persistently colonized and responsible for 10% of acquisitions) and maximum (B) (1% of the HCWs is persistently colonized and responsible for 50% of acquisitions). The efficacy of HCW decolonization is 100%. Lines with patient decolonization (100% efficacious) and only isolation (50% efficacious) are added for comparison.
