Heterosexual Transmission of Community-Associated Methicillin-Resistant Staphylococcus aureus

Abstract
Community-associated (CA) methicillin-resistant Staphylococcus aureus (MRSA) has emerged as a major cause of cutaneous and invasive infections [1,2–3]. CA-MRSA infection occurs in a wide range of individuals, including members of sports teams, military recruits, and children in day care facilities [4, 5]. Increasingly, reports have also suggested behavioral risks, including injection drug use and poor personal hygiene [4, 6,7–8]. Absent from this list have been reports of heterosexual activity as a potential means of CA-MRSA transmission. This potential means of transmission might help to explain the ability of these new strains to become established in what would otherwise be considered low-risk communities. In this report, we describe 3 households in which heterosexual transmission of CA-MRSA is likely to have occurred.
