[Two cases of invasive Haemophilus influenzae type f infection]. / To tilfaelde af invasive infektioner med Haemophilus influenzae type f.

Two cases of invasive Haemophilus influenzae type f infection are presented: a three-week-old boy with meningitis and a 62-year-old woman with arthritis and bacteremia. Since 1993 vaccination against H. influenzae type b (Hib) has been offered to Danish children. The result has been a remarkable decrease in invasive Hib disease. However, physicians need to be aware of the existence of non-type b invasive H. influenzae disease.
