Summary
Objectives

The relationship between community-associated methicillin-resistant
Staphylococcus aureus (CA-MRSA) nasal colonization and subsequent
infection in children is unknown. We sought to define risk factors for
skin and soft tissue infection (SSTI) in community children.

Methods

A prior study measured S. aureus nasal colonization prevalence for
1300 community children. To detect subsequent SSTI in these children
or a household member, surveys were administered 6 and 12 months
following enrollment.

Results

SSTIs were reported by 56/708 (8.1%) respondents during the initial
6-month interval. SSTI developed in 6/26 (23%) initially colonized
with MRSA, 16/194 (8%) with methicillin-sensitive S. aureus
colonization, and 34/474 (7%) not colonized with S. aureus (MRSA vs.
not MRSA, univariate analysis, p=0.014). In multivariable analysis,
factors associated with SSTI included history of SSTI in the child
during the year preceding enrollment (p<0.01) and SSTI in household
contacts during the follow-up interval (p<0.01); MRSA nasal
colonization approached statistical significance (p=0.08).

Conclusions

In the current era of community MRSA transmission, SSTI is a disease
of households, with recurrences in index cases and occurrences among
household contacts. Children with MRSA colonization may be at risk for
subsequent SSTI. Further study of MRSA transmission dynamics in
households and preventive strategies should receive high priority.
