In 2020, there was a further decrease in the number of registered cases, but it was much\u00a0more pronounced than in the preceding years. As in previous years, no deaths from giardiasis were recorded.\u00a0The downward trend in hospitalizations continued and in 2020 they accounted for approximately 12.6% of all\u00a0cases, in 2019 the percentage was 15.2% and in 2018 \u2013 19.4%. Most cases met the definition of a confirmed case,\u00a0with 1 patient meeting the criteria of a probable case. In 2020, 6 outbreaks of giardiasis were reported, which\u00a0is a decrease compared to 2019 (12 outbreaks) and thus means a reversal of the upward trend occurring at least\u00a0since 2017.<br \/><strong>CONCLUSIONS.<\/strong> Data for 2020 should be interpreted taking into account the effect of the COVID-19 pandemic,\u00a0which could have resulted in changes in long-term trends, but in particular contributed to a strong decrease in\u00a0the number of cases not only of giardiasis, but also of other infectious diseases. In 2020, almost all EU\/EEA\u00a0countries reported a decrease in the incidence of giardiasis similar to that in Poland. However, as in 2019, in\u00a02020 Poland differed from other EU\/EEA countries in terms of incidence by age and sex.<\/p>\n<p><strong>STRESZCZENIE<\/strong><br \/><strong>CEL.<\/strong> Ocena sytuacji epidemiologicznej giardiozy w Polsce w 2020 r.<br \/><strong>MATERIA\u0141 I METODY.<\/strong> Ocena sytuacji epidemiologicznej giardiozy w Polsce w 2020 r. zosta\u0142a przeprowadzona\u00a0na podstawie zagregowanych danych z rocznych biuletyn\u00f3w \u201eChoroby zaka\u017ane i zatrucia w Polsce\u201d za\u00a0lata 2006-2020, danych o indywidualnych przypadkach gromadzonych na potrzeby nadzoru epidemiologicznego\u00a0w systemie EpiBaza oraz danych z dochodze\u0144 w ogniskach przenoszonych drog\u0105 pokarmow\u0105 zgromadzonych\u00a0w Rejestrze Ognisk Epidemicznych (ROE).<br \/><strong>WYNIKI.<\/strong> Liczba nowych przypadk\u00f3w giardiozy odnotowanych w Polsce w roku 2020 r. wynosi\u0142a 358 zachorowa\u0144\u00a0(wsp\u00f3\u0142czynnik zapadalno\u015bci 0,9 na 100 tys. ludno\u015bci) i by\u0142a oko\u0142o 2 razy ni\u017csza ni\u017c w 2019 r.
