In this cross-sectional multicenter study, we determined the rate of nasal carriage of methicillin-resistant Staphylococcus aureus (MRSA) in children admitted to 9 training hospitals in Switzerland during 1 month. From 1337 patients, 1363 nasal swabs were obtained (mean age 6.1 years, median 4.7 years, interquartile range 1.3–10.4 years) and 562 (41.3%) grew S. aureus. Only one isolate was MRSA (0.18%) which encoded mecA and femA genes as well as SCCmec type IV, whereas Panton-Valentine leukocidin (PVL) was absent.
