Does nasal colonization or mupirocin treatment affect recurrence of methicillin-resistant Staphylococcus aureus skin and skin structure infections?

Some patients with community-associated methicillin-resistant Staphylococcus aureus skin and skin structure infections have experienced frequent recurrences. We performed a retrospective study and determined that the presence of nasal colonization did not affect recurrence and nasal mupirocin treatment marginally decreased recurrence.
