This study discusses in detail bacterial meningitis and\/or encephalitis in which the etiological<br \/>factors are: <em>Neisseria meningitidis, Streptococcus pneumoniae, Haemophilus influenzae<\/em> and viral - in Poland,\u00a0most often caused by tick-borne encephalitis virus. In addition to routine epidemiological surveillance of diseases\u00a0caused by these etiological factors, mandatory and recommended vaccinations are carried out in Poland aimed\u00a0at reducing the number of cases caused by <em>N. meningitidis, S. pneumoniae, H. influenzae<\/em> and TBEV.<br \/><strong>AIM OF THE STUDY.<\/strong> The aim of the study is to assess the epidemiological situation of meningitis and\u00a0encephalitis in Poland in 2019.<br \/><strong>MATERIAL AND METHODS.<\/strong> The epidemiological situation of meningitis and encephalitis in Poland was\u00a0assessed on data sent to NIPH NIH - NRI by voivodeship sanitary-epidemiological stations and published in\u00a0the annual bulletin \u201cInfectious diseases and poisoning in Poland in 2019\u201d and \u201cVaccinations in Poland in 2019\u201d.<br \/><strong>RESULTS.<\/strong> In 2019, a total of 2,239 cases of meningitis and encephalitis were registered in Poland. This\u00a0is a decrease by approximately 19,9% compared to 2018. In the case of bacterial infections, including\u00a0neuroborreliosis, the number of cases decreased by 27%, from 1265 to 921 cases. In the group of viral\u00a0infections, a decrease by 14% (from 1,533 to 1,318 cases) was recorded. In 31% of all the cases of bacterial\u00a0etiology, the etiological factor was one of three: <em>Neisseria meningitidis, Streptococcus pneumoniae<\/em> and\u00a0<em>Haemophilus influenzae<\/em>. Infections of viral etiology accounted for 58.9% of all registered cases. Compared\u00a0to 2018, the number of <em>S. pneumoniae<\/em> cases decreased by 14.6%, and in the case of <em>N. meningitidis<\/em> by 6.9%.<br \/>In the case of <em>H. influenzae<\/em>, there was an increase in the number of cases, compared to the previous year. In\u00a0addition, there was a slight increase in the number of cases of tick-borne encephalitis \u2013 from 197 cases in 2018\u00a0to 265 cases in 2019 (an increase of 34.5%).<br \/><strong>SUMMARY AND CONCLUSION.<\/strong> The analysis showed a generally declining disease trend, both in bacterial<br \/>and viral meningitis and encephalitis. Only in cases caused by H. influenzae and tick-borne encephalitis virus,\u00a0an increase was observed compared to the previous year. Meningitis and encephalitis continues to be a challenge\u00a0for the healthcare system, with particular emphasis on the correct differentiation of the etiology at an early stage\u00a0of infection detection.<\/p>\n<p><strong>STRESZCZENIE<\/strong><br \/><strong>WST\u0118P.<\/strong> Najcz\u0119stsz\u0105 postaci\u0105 chor\u00f3b zaka\u017anych uk\u0142adu nerwowego jest zapalenie opon m\u00f3zgowo-rdzeniowych\u00a0i\/lub m\u00f3zgu.
