MENINGITIS DUE TO HAEMOPHILUS-INFLUENZAE TYPE-F

Objective: To describe a case of Haemophilus influenzae type f (Hif) m eningitis occurring in the H. influenzae type b (Hib) vaccine era. Res ults: Successful treatment of a case of Hif meningitis in a previously vaccinated 3-year-old girl is described. The outcome was complicated by deafness. No underlying immunosuppression was demonstrated. Conclus ions: Despite the great success of Hib vaccines in reducing invasive d isease due to H. influenzae, cases of H. influenzae meningitis continu e to occur, caused by less common encapsulated serotypes. Whether ther e will be an increase in the number of these cases in the vaccine era is unknown and infection due to non-b serotypes requires close monitor ing.
