The highest percentage\u00a0of registered cases of pertussis concerned people aged 15 and over. The causes of the increased incidence of\u00a0pertussis are a complex problem. Immunity after pertussis vaccination is unstable, disappears within 4-12 years,\u00a0and the risk of the disease increases with time after the last dose of the vaccine. Due to the loss of protection\u00a0against pertussis in adults, it is important to repeat immunization with dTpa every 10 years.<br \/><strong>OBJECTIVE.<\/strong> The aim of the study was to assess the epidemiological situation of pertussis in Poland in 2018-2019 compared to the situation in previous years, with particular emphasis on the assessment of the vaccination\u00a0status of children against pertussis.<br \/><strong>MATERIAL AND METHODS.<\/strong> The assessment of the epidemiological situation of pertussis in Poland was\u00a0performed on the basis of the results of the analysis of unit reports of pertussis registered in the NIPH-NIH\u00a0through the SRWE system and data from the bulletins \u201cInfectious diseases and poisonings in Poland\u201d for 2018\u00a0and 2019 and the bulletins \u201cVaccinations in Poland\u201d for 2018 and 2019.<br \/><strong>RESULTS.<\/strong> In 2018, 1 548 were registered, and in 2019 \u2013 1 629 cases of pertussis. The incidence was respectively:\u00a04.0 and 4.2 per 100 000 population and was lower compared to the incidence in 2017 (8.0). The highest incidence\u00a0of pertussis was in the age group 0-4 years (20.6 and 23.6 respectively), and high in children and adolescents\u00a0aged 5-9 (10.9 and 11.5 respectively) and 10-14 years (respectively: 12.2 and 11.2 - per 100 000 population).<br \/>About half of the cases concerned people over 15 years of age. In general, a higher incidence among women\u00a0was observed than in men, as well as a higher incidence in cities than in rural areas. In 2018, among people with\u00a0pertussis, 434 people (i.e. 28%) and in 2019 \u2013 482 people (i.e. 29.6%) were hospitalized. In 2019, one fatal case\u00a0of the disease was reported to the epidemiological surveillance system.<br \/><strong>SUMMARY AND CONCLUSIONS.<\/strong> In Poland, in the years 2018-2019, there was a decrease in the number\u00a0of cases of pertussis, the most common were children under the age of four (the highest incidence). A worrying\u00a0trend is the decreasing number of vaccinations in children aged 2 years against pertussis covered by compulsory\u00a0primary vaccinations in individual provinces. In the current epidemiological situation, the best way to prevent\u00a0new cases of pertussis is to use vaccination according to the current regimen and to recommend to adults\u00a0a single dose of dTpa vaccination, which should be repeated every 10 years.<\/p>\n<p><strong>STRESZCZENIE<\/strong><br \/><strong>WST\u0118P.<\/strong> Krztusiec jest endemiczn\u0105, wysoce zara\u017aliw\u0105 chorob\u0105, kt\u00f3rej mo\u017cna zapobiega\u0107 poprzez szczepienia.
