Return of the staph

When a young boy’s boils keep coming back, what is the best course of action?

Leo, a nine-year-old, previously well boy, is brought to his GP by his mother, who is visibly upset and stressed.

Leo has a six-month history of recurrent furunculosis over the thighs and lower torso, which are becoming increasingly frequent.

The lesions are painful and large, sometimes reaching more than 6cm in diameter. They are now recurring every 3-4 weeks. There is no clear precipitant. 

Leo has been systemically well. However, the associated pain is affecting his sleep and limiting his ability to participate in sport.
