Molecular characteristics of S. aureus isolates from participants

	Unadjusted mecA (%)	Adjusted mecA (%)	Unadjusted PVL (%)	Adjusted PVL (%)
Urban county	10/86 (11)	7/56 (12.5)	0/86 (0)	0/56 (0)
Rural county	2/61 (3)	1/42 (2)	7/61 (11)	5/42 (11)
Total	12/147 (8)	8/98 (8)	7/147 (4.8)	5/98 (5)

Note: Unadjusted values include all S. aureus isolates from participants broken down my county. Adjusted values include only a single copy of isolates with the same molecular profile (same spa type and presence/absence of mecA and PVL) to account for familial clustering and the presence of clonal isolates in the nares and oropharynx of adult participants.

PVL, Panton-Valentine leukocidin.
