Relationship between Overcrowding, Other Markers of Poverty and Community Acquired Methicillin Resistant Staphylococcus aureus

We studied familiar SSTI at community level as the presence of any of the following conditions: suppurative lesions, wound infections, consultations or prior hospitalizations for these diseases, isolation of Staphylococcus aureus by culture in a member of the family, treatment with Beta-lactams, cephalexin, co-trimoxazole, clindamycin, erythromycin, azithromycin or clarithromycin for SSTI, mupirocin treatment, and drainage of suppurative lesions. We could determine a statistical association of these infections with familial overcrowding and location of the home at the poorer neighborhoods.
