Recurrent acute otitis media occurring within one month from completion of antibiotic therapy: relationship to the original pathogen

Abstract

Most recurrent AOM episodes occurring within 1 month from completion of antibiotic therapy are in fact new infections. Most of the true bacteriologic AOM relapses occur within 14 days after completion of therapy, but even during this time interval most of the recurrences are caused by new pathogens. H. influenzae is very unlikely to cause true bacteriologic AOM relapses 14 days or later after completion of therapy.
