Abstract：
UNASSIGNED: The aim of this study is to compare the epidemiological situation of legionellosis in Poland in 2018-2021 to prior years, taking into account the impact of the COVID-19 pandemic in 2020-2021.
UNASSIGNED: The assessment is based on national surveillance data published in the annual bulletin \"Infectious Diseases and Poisons in Poland\" from 2013 to 2021, as well as data from Legionnaires\' disease case reports collected and sent to the Department of Epidemiology of Infectious Diseases and Surveillance NIPH NIH - NRI by sanitary and epidemiological stations or submitted to EpiBase.
UNASSIGNED: In Poland, both Legionnaires\' disease (an acute infection that progresses to pneumonia) and Pontiac fever (a mild, flu-like sickness) are reported. In 2018-2021, a total of 255 cases of legionellosis were registered, including 236 cases of Legionnaires\' disease and 19 cases of Pontiac fever. Each year, there was an increase in the number of notifications compared to the annual median number of cases from 2013-2017. The annual incidence rate in 2019 (0.23 per 100,000 population) was the highest since the start of legionellosis case registration in Poland. It declined again during the years of the COVID-19 pandemic. The notifications occurred throughout the country, but the highest notification rate was observed in the western belt of voivodeships. Pomorskie reported the highest incidence, accounting for more than 20% of all registered cases. The median incidence of Legionnaires\' disease in men (0.23 per 100,000) was more than twice that of women (0.10), with the highest incidence (0.58) recorded in men 65 years of age or older. All indigenous cases of Legionnaires\' disease were sporadic; all but three patients were hospitalized. State Sanitary Inspection reported 26 fatal cases of Legionnaires\' disease (mortality = 11%). Twenty-four cases were linked to contaminated water systems in health-care settings, and 21 cases were likely associated with travel abroad.
UNASSIGNED: Although the number of notifications has increased in recent years, Legionnaires\' disease is still an infrequently diagnosed respiratory infection in Poland, and the reported incidence remains one of the lowest in the entire EU. The most affected demographic group is men aged 65 and older. Improving the early diagnosis of Legionnaires\' disease in healthcare settings remains a priority.

摘要：
■这项研究的目的是将2018-2021年波兰军团菌病的流行病学情况与往年进行比较，考虑到2020-2021年COVID-19大流行的影响。
评估基于2013年至2021年年度公报“波兰传染病和毒药”中公布的国家监测数据，以及由卫生和流行病学站收集并发送给NIPHNIH-NRI传染病流行病学和监测部门或提交给EpiBase的军团病病例报告数据。
■在波兰，军团病（一种发展为肺炎的急性感染）和庞蒂亚克热（轻度，类似流感的疾病)被报告。在2018-2021年，共有255例军团菌病登记，其中军团病236例，庞蒂亚克热19例。每一年,与2013-2017年的年度病例数中位数相比,呈报数量有所增加.2019年的年发病率（每10万人0.23）是波兰军团菌病病例登记开始以来的最高水平。在COVID-19大流行的几年里，它再次下降。通知发生在全国各地，但通知率最高的是西部省份。Pomorskie报告的发病率最高,占所有登记案件的20%以上。男性军团病的中位发病率（0.23/100,000）是女性（0.10）的两倍多，在65岁或以上的男性中发病率最高(0.58)。所有本土军团病病例均为散发性；除三名患者外，其他所有患者均住院。国家卫生检查报告了26例退伍军人病致命病例（死亡率=11％）。24例病例与卫生保健机构中的受污染水系统有关，21例可能与出国旅行有关。
■尽管近年来通知的数量有所增加，军团病在波兰仍然是一种罕见的呼吸道感染，报告的发病率仍然是整个欧盟最低的国家之一。受影响最大的人口群体是65岁及以上的男性。在医疗机构中改善军团病的早期诊断仍然是当务之急。
