MRSA concentrations at baseline scenario without intervention. The Y-axis represents MRSA concentrations on the entire surface area (cfu/2000 cm²) from the seven compartments. These compartments starting with the highest MRSA concentrations, are: 1) the porous surface in the colonized patient’s room; 2) the nonporous surface in the colonized patient’s room; 3) the exposed skin and hands of the colonized patient; 4) the exposed skin and hands of the HCW; 5) the nonporous surface in the uncolonized patient’s room; 6) the porous surface in the uncolonized patient’s room; and 7) the exposed skin and hands of the uncolonized patient.
