The natural history of contemporary Staphylococcus aureus nasal colonization was evaluated in community children during a 1-year period. Methicillin-susceptible S. aureus nasal carriage was more persistent than methicillin-resistant S. aureus nasal carriage, which was usually self-limited. Children with persistent staphylococcal colonization often carried identical strains. Identification of persistent methicillin-resistant S. aureus carriers might inform strategies for decolonization and reduction of staphylococcal transmission.
