Recurrent familial staphylococcal furunculosis causes severe physical and especially socio-psychological problems to the families involved. In the present study 6 families with 28 persons were not treated with antibiotics but with a combination of chlorhexidine bathing, nasal 1% chlorhexidine gel and improved cleaning and hygiene in the surroundings. The infecting Staphylococcus aureus strain was eradicated from the surroundings and the skin in all 6 families, but several of the family members still retained the strain in the nose. All family members were, however, cured and remained without infections during an observation period of 2 years.
