Distribution of subjects colonized with strain-specific MRSA over time under selected scenarios derived from the deterministic model. The curve Observed represents the percent of colonized subjects over time based on the observed data; Scenario 1 shows the percent of colonized subjects under the assumption of no intra-facility cross-transmission; Scenario 2 reflects the percent of colonized subjects when MRSA clearance rates are increased two-fold; Scenario 3 represents the percent of colonized over time when all positive MRSA admissions are eliminated; Scenario 4 shows the percent of colonized over time when a half of all positive MRSA admissions are eliminated. a Percent colonized with non-USA300; b Percent colonized with USA300; c Percent co-colonized with non-USA300 and USA300
