Hemophilus influenzae type f meningitis in an adolescent.

A 17-year-old male with Hemophilus influenzae type f meningitis is reported. Recent studies which suggest that the incidence of H. influenzae meningitis in older individuals is increasing are reviewed. Therefore, we recommend that antimicrobial therapy directed against H. influenzae be included in the initial management of older children, adolescents, and adults with acute bacterial meningitis.
