The incidence per 100,000 population was 14.3 for total salmonellosis, 13.8 for intestinal\u00a0salmonellosis and 0.44 for extra-intestinal salmonellosis. Sanitary-epidemiological stations registered 5,349\u00a0confirmed cases and 121 probable cases of salmonellosis. Due to intestinal salmonellosis, 63.9% of all patients\u00a0were hospitalized, while for extra-intestinal salmonellosis 153 patients or 91.1% of cases, were hospitalized.\u00a0<br \/>The increase in the number of salmonellosis cases in 2020 started in June, while the peak of the incidence was\u00a0in August. Among the voivodeships, the highest incidence of salmonellosis was registered in the Podkarpackie\u00a0voivodeship 33.3\/100,000 population, the lowest in Zachodniopomorskie 6.1\/100,000 population. Cases in the\u00a00-4 age group accounted for 45.2% of all salmonellosis cases in 2020. Among extra-intestinal salmonellosis,\u00a063.1% were people aged 60+. Sanitary-epidemiological stations registered 131 food poisoning outbreaks caused\u00a0by Salmonella bacilli in the ROE system, 108 of these outbreaks were caused by the Enteritidis serotype. In\u00a02020, the most common serotypes were S. Enteritidis 70% of all recorded salmonellosis, S. Typhimurium 1.9%,\u00a0and S. Infantis 0.54%. There were 9 deaths due to Salmonella infection.<br \/><strong>CONCLUSIONS.<\/strong> The COVID-19 pandemic and the associated restrictions introduced in the country, as well\u00a0as increased hygiene through more frequent washing and disinfection of hands, could have contributed to\u00a0a reduction of almost 69% in the number of salmonellosis cases registered in 2020, in Poland, compared to 2019.<br \/>This is a 82% decrease in relation to 2018. There was also a decrease in the number of food poisoning outbreaks\u00a0caused by Salmonella bacilli, while at the same time their percentage in the total number of outbreaks increased.<br \/>On the one hand, the implemented restrictions could have had an impact on the decrease in the number of\u00a0cases and outbreaks, on the other hand, worse access to medical care and diagnostics, most likely deepened the\u00a0underestimation of these cases in the country observed for years, and distorted the real picture of the situation.<\/p>\n<p><strong>STRESZCZENIE<\/strong><br \/><strong>CEL.<\/strong> Celem pracy jest ocena sytuacji epidemiologicznej zachorowa\u0144 na salmonelozy w Polsce w 2020 roku\u00a0w por\u00f3wnaniu z poprzednimi latami.<br \/><strong>MATERIA\u0141 I METODY.<\/strong> Ocen\u0119 sytuacji epidemiologicznej przeprowadzono na podstawie danych\u00a0przekazanych do Zak\u0142adu Epidemiologii Chor\u00f3b Zaka\u017anych i Nadzoru NIZP PZH - PIB przez stacje\u00a0sanitarno-epidemiologiczne za po\u015brednictwem Systemu EpiBaza oraz systemu Rejestr Ognisk Epidemicznych\u00a0(ROE), a tak\u017ce na podstawie danych opublikowanych w rocznym biuletynie \u201eChoroby zaka\u017ane i zatrucia w Polsce\u00a0w 2020 roku\u201d (NIZP PZH-PIB, GIS, Warszawa, 2021) oraz z informacji uzyskanych z laboratori\u00f3w stacji\u00a0sanitarno-epidemiologicznych i danych Departamentu Bada\u0144 Demograficznych G\u0142\u00f3wnego Urz\u0119du Statystycznego.<br \/><strong>WYNIKI.<\/strong> W Polsce w 2020 roku w nadzorze sanitarno-epidemiologicznym zarejestrowano \u0142\u0105cznie 5 470\u00a0przypadk\u00f3w salmoneloz, 5 302 to przypadki salmonelozy jelitowej, pozosta\u0142e 168 to salmoneloza pozajelitowa.<br \/>Zapadalno\u015b\u0107 na 100 tys. populacji wynios\u0142a dla salmoneloz og\u00f3\u0142em 14,3, dla salmoneloz jelitowych 13,8\u00a0a dla salmoneloz pozajelitowych 0,44.
