It is characterized by a rash with rapid seeding of small red papules. The course of the disease is mild, but in people with weakened immunity it may be severe.<\/jats:p><\/jats:sec><jats:sec><jats:title>Objective<\/jats:title><jats:p>The aim of the study was to assess the epidemiological situation of chickenpox in Poland in 2022 compared to the situation in previous years.<\/jats:p><\/jats:sec><jats:sec><jats:title>Material and Methods<\/jats:title><jats:p>Data from epidemiological surveillance, including mandatory reporting of cases by physicians, were used to assess the epidemiological situation of chickenpox in Poland.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>In 2022, 171 708 cases of chickenpox were recorded, of which 87.5% were children under  9 years old. Hospitalization due to chickenpox was not one of the most common, the percentage of hospitalized cases oscillated between 0.12% and 1.24% depending on the voivodeship. Analyzing the incidence for the whole of Poland for the last 10 years, we see a drastic decrease from 470.6 in 2019 to 186.6 in 2020 and another decrease in 2021 to 151.1 per 100 000, to then return to an incidence of 453.9 in 2022.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>The incidence of chickenpox in 2022 returned to pre-pandemic levels, similar to those seen in 2016-2018. Despite preventive measures taken throughout the pandemic, significant incidence was observed, underlining the key role of vaccination in preventing this disease. The use of a quadrivalent vaccine against rubella, measles, mumps, and varicella could help reduce the costs associated with chickenpox, with a small increase in the costs of the vaccination program.<\/jats:p><\/jats:sec>","DOI":"10.32394\/pe\/195722","type":"journal-article","created":{"date-parts":[[2024,11,12]],"date-time":"2024-11-12T17:34:59Z","timestamp":1731432899000},"source":"Crossref","is-referenced-by-count":1,"title":["Chickenpox in Poland in 2022"],"prefix":"10.32394","author":[{"given":"Jakub Maciej","family":"Zbrze\u017cniak","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Iwona","family":"Paradowska-Stankiewicz","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"17323","published-online":{"date-parts":[[2024,11,12]]},"container-title":["Przeglad Epidemiologiczny"],"original-title":["Ospa wietrzna w Polsce w 2022 roku"],"link":[{"URL":"https:\/\/www.przeglepidemiol.pzh.gov.pl\/pdf-195722-116253","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.przeglepidemiol.pzh.gov.pl\/pdf-195722-116253","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,11,12]],"date-time":"2024-11-12T17:34:59Z","timestamp":1731432899000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.przeglepidemiol.pzh.gov.pl\/Ospa-wietrzna-w-Polsce-w-2022-roku,195722,0,2.html"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2024,11,12]]},"references-count":0,"alternative-id":["195722"],"URL":"https:\/\/doi.org\/10.32394\/pe\/195722","relation":{},"ISSN":["0033-2100","2545-1898"],"issn-type":[{"value":"0033-2100","type":"print"},{"value":"2545-1898","type":"electronic"}],"subject":[],"published":{"date-parts":[[2024,11,12]]}}}
