[Epidemiology and etiology of bacterial meningitis in postnatal period].

In south-east Poland in the years 1993 till 1995 we observed a decreasing number of meningococcal meningitis in children and a growth of cases caused by Haemophilus influenzae. Changes in ethiology of bacterial meningitis should give a reason for epidemiological research in Poland because there is a chance to reduce number of patients when wider use of new vaccines is introduced.
