Aggregate data\u00a0published in the annual bulletins \u201cInfectious Diseases and Poisonings in Poland\u201d and \u201cVaccinations in Poland\u201d\u00a0were also used.<br \/><strong>RESULTS.<\/strong> In 2018, a total of 3 196 hepatitis B cases were registered, which corresponds to an incidence of\u00a08.3 cases per 100,000 population. Acute hepatitis B cases accounted for about 1.3 % of total. The incidence of\u00a0acute hepatitis B was lower by 33% than in 2017 and lower by 44% than median of the years 2012-2016. No\u00a0acute cases were reported among children and adolescents aged 0-19 years and in the age group 20-24. The\u00a0incidence of chronic and unknown (in terms of the stage) was lower by 4.5% than in the previous year however,\u00a0in comparison to median incidence of chronic hepatitis B in 2012-2016 an increase of 17% was noted. As in the\u00a0previous years, acute, chronic and unknown stage (UNK) hepatitis B were more often detected in men and in\u00a0urban residents. The dominant route of transmission of HBV infections still remains procedures performed in\u00a0medical settings - 86% of cases with a known transmission route. The coverage with the third HBV vaccine\u00a0dose in children aged two years was 91 % and remains ( since 2017) below the 95% required in the elimination\u00a0strategy. In 2018 three people died due to acute hepatitis B and 35 people due to chronic hepatitis B.<br \/><strong>CONCLUSIONS.<\/strong> In 2018 decrease in the incidence of acute and chronic hepatitis B was observed. In group\u00a0of persons born after 1994 covered by obligatory hepatitis B vaccinations as newborns no acute cases have been\u00a0reported, however, a progressive decline in children\u2019s vaccination coverage poses a risk for new HBV infection\u00a0also among people subjected to mandatory vaccinations. Maintenance of a low incidence of acute hepatitis B\u00a0requires improvement in carrying out of mandatory vaccination among newborns and further recommendation\u00a0of vaccination for all persons previously unvaccinated. A slight decline in the detection of chronic and UNK\u00a0cases may be related to the number of tests performed in a given year.<br \/><br \/><strong>STRESZCZENIE<\/strong><br \/><strong>CEL PRACY.<\/strong> Ocena sytuacji epidemiologicznej wirusowego zapalenia w\u0105troby typu B w Polsce w 2018 r.\u00a0w por\u00f3wnaniu z sytuacj\u0105 w latach wcze\u015bniejszych.<br \/><strong>MATERIA\u0141 I METODY.<\/strong> Przeprowadzono ocen\u0119 sytuacji epidemiologicznej na podstawie wynik\u00f3w analizy\u00a0danych indywidualnych o zachorowaniach na wzw B i zaka\u017ceniach HBV zarejestrowanych przez stacje sanitarno-epidemiologiczne w elektronicznym Systemie Rejestracji Wywiad\u00f3w Epidemiologicznych - SRWE.
