title: [Meningitis and encephalitis in Poland in 2009].
abstract: In Poland, 2 517 cases of neuroinfections were reported in 2009, of which 865 had bacterial aetiology, 1 244--viral aetiology, and 408-- other or unknown origin. The etiological agent was determined in 493 (57%) cases of bacterial neuroinfections. Among them Neisseria meningitidis was found in 190 cases, Haemophilus influenzae type B (Hib) in 13 cases and Streptococcus pneumoniae in 163 cases. An increasing trend in pneumococcal infections incidence has been observed since 2005, and a substantial decrease of Hib incidence, related to increasing vaccination coverage. Viral neuroinfections incidence in 2009 increased compared to year 2008. Among confirmed cases, there were 351 cases of tick-borne encephalitis. Most of the cases were reported from endemic areas of north-eastern part of the country.
