Staph aureus: Is the most common organism involved. You may be able to reduce the frequency of recurrence by trying to eliminate nasopharyngeal and skin carriage. Use Mupirocin ointment in nares bid for a month combined with bathing solely with chlorhexadine containing soap for a month. Do not use other soaps because it washes off the film of chlorhexadine created.
