Study Finds MRSA on Common Household Surfaces
AHRQ-funded researchers at the Washington University School of Medicine in St. Louis, Missouri, found methicillin-resistant Staphylococcus aureus (MRSA) on household surfaces in 46 percent of homes where children had a culture-positive active or recent community-associated MRSA infection. Researchers took samples from 50 households and found MRSA on commonly touched surfaces, most frequently on bed linens (18 percent), TV remote-control devices (16 percent), and bathroom hand towels (15 percent). There was also an association between MRSA contamination and more individuals present per 1,000-square-foot area. MRSA strains matching those infecting and colonizing household members were present on commonly handled surfaces, a factor that likely perpetuates MRSA transmission and recurrent disease. The study, “Contamination of Environmental Surfaces WithStaphylococcus aureus in Households With Children Infected With Methicillin-Resistant S. aureus,” was published online September 8 inJAMA Pediatrics.
