Evaluation of the epidemiological situation of hepatitis B in Poland in 2017 in relation to previous\u00a0years.<br \/>MATERIAL AND METHODS. Analysis was carried out on data on hepatitis B and HBV infections registered\u00a0in the Epidemiological Interview Registration System (SRWE) kept in NIPH-NIH. Aggregate data published\u00a0in the annual bulletins \u201cInfectious Diseases and Poisonings in Poland\u201d and \u201cVaccinations in Poland\u201d were also\u00a0used.<br \/><strong>RESULTS<\/strong>. In 2017, a total of 3,363 cases of hepatitis B were registered, including 29 cases of HBV and HCV\u00a0co-infections. The number of acute hepatitis B cases was 56, accounting for 1.7% of all hepatitis B cases. The\u00a0incidence of acute hepatitis B was 0.15 per 100,000 population. In comparison with 2016 there was a slight\u00a0increase the incidence of acute hepatitis B (In 2016, incidence was 0.13 per 100,000 population and the number\u00a0of acute hepatitis B was 50). 887 cases of chronic and 2420 of uknown stage hepatitis B were registered (26.4%\u00a0and 71.9%, respectively) The incidence of chronic or UNK stages was lower by almost 12% than in previous\u00a0year. As in previous years, incidence varied a lot at level of voivodeships. The highest incidence was recorded\u00a0in Pomorskie voivodeship (15 per 100,000). Acute, chronic and unknown stage (UNK) hepatitis B were more\u00a0often detected in men and in urban residents. In most of HBV cases the probable route of transmission were still\u00a0medical procedures. In 2017, HBV vaccination coverage in children with the third HBV vaccine dose for the first\u00a0time in many years decreased below the required 95% in the elimination strategy.<br \/><strong>CONCLUSIONS<\/strong>. Compared to the previous year a similar number of cases of acute hepatitis B was registered.<br \/>The good epidemiological situation in the area of acute hepatitis B is mainly the result of effective vaccinations\u00a0of newborns, however, there has been observed a systematic decline in children\u2019s vaccination coverage for\u00a0several years. Slight annual fluctuations in the number of chronic and UNK cases detected may be related to the\u00a0number of tests performed in a given year.<br \/><br \/><strong>STRESZCZENIE<\/strong><br \/><strong>CEL PRACY<\/strong>: Ocena sytuacji epidemiologicznej wzw B w Polsce w 2017 r. w odniesieniu do lat wcze\u015bniejszych.<br \/><strong>MATERIA\u0141 I METODY<\/strong>. Analizowano dane o zachorowaniach na WZW typu B i zaka\u017ceniach HBV, kt\u00f3re\u00a0zarejestrowano w elektronicznym systemie Rejestracji Wywiad\u00f3w Epidemiologicznych dzia\u0142aj\u0105cym w NIZP-PZH. Podczas analizy korzystano tak\u017ce z danych opublikowanych w biuletynach rocznych: \u201eChoroby zaka\u017ane\u00a0i zatrucia w Polsce\u201d oraz \u201eSzczepienia ochronne w Polsce\u201d.<br \/><strong>WYNIKI<\/strong>. W 2017 roku zg\u0142oszono 3363 przypadki wirusowego zapalenia w\u0105troby typu B, w tym 29 zaka\u017ce\u0144,\u00a0w kt\u00f3rych wyst\u0105pi\u0142o wsp\u00f3\u0142zaka\u017cenie HCV.
