[Type B Haemophilus influenzae infections: epidemiology, vaccination, chemoprophylaxis].

In the new countries of the Federal Republic Germany the incidence of systemic Hib-infections is lower than in the old FRG. In children under the age of 5 years the incidence of Hib-meningitis is 8/100,000 and of all systemic Hib-diseases about 17/100,000. By Hib-vaccination (PRP-D) severe diseases can be prevented. The recommended chemoprophylaxis with Rifampicin is important in this connection, too.
