Approximately 3.5% of children at TCH have a proven recurrence of S. aureus infection within 12 months; we believe this is a minimal estimate and that overall at least 10% of children have recurrences. There is no consensus on the best strategies for preventing recurrent S. aureus infections or spread of S. aureus among family members. At TCH, in addition to routine preventative measures, we often recommend for the patients to take a bath at least twice a week in water to which one teaspoon of household bleach (Clorox) has been added per gallon of water. Anecdotally this approach has decreased the recurrence rate of S. aureus infections, but this common strategy among dermatologists has not been formally evaluated and is thus controversial.
