Abstract
We assessed characteristics associated with community-associated methicillin-resistant Staphylococcus aureus(CA-MRSA) carriage among residents of 22 nursing homes. Of MRSA-positive swabs, 25% (208/824) were positive for CA-MRSA. Median facility CA-MRSA percentage was 22% (range, 0%-44%). In multivariate models, carriage was associated with age less than 65 years (odds ratio, 1.2; [Formula: see text]) and Hispanic ethnicity (odds ratio, 1.2; [Formula: see text]). Interventions are needed to target CA-MRSA.
