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.
