A Washington University School of Medicine study suggests that MRSA colonization rates among household contacts of children with Staphylococcus aureus appear to be higher than those of the general population. Of household contacts of children with MRSA, MSSA, or both:
53% were colonized with S aureus.
19% were colonized with MRSA.
32% were colonized with MSSA.
2% were colonized with both MRSA and MSSA.
Parents were more likely than other contacts to be colonized with MRSA (odds ratio, 1.72).
