OBJECTIVE

The aim of this study is to assess the epidemiological situation of yersiniosis in Poland in 2015 and 2016 in comparison to the previous years.

MATERIAL AND METHODS

The evaluation is based on analysis of data from the annual bulletins „Infectious diseases and poisoning in Poland” (4,5), information from individual yersiniosis case reports sent to the Department of Epidemiology of Infectious Diseases and Surveillance, NIPH-NIH by regional sanitaryepidemiological stations, information on outbreaks delivered by local sanitary-epidemiological stations through the system „Rejestr Ognisk Epidemicznych” (Electronic Registry of Epidemic Outbreaks) and data on deaths from the Department of Demographic Studies of the Central Statistical Office.

RESULTS

The number of registered yersiniosis cases in Poland in 2015 and 2016 was the same – 205 cases, corresponding to annual incidence of 0.53/100 000. Among them in 2015 there were 172 intestinal yersiniosis cases and 33 extraintestinal yersiniosis cases and in 2016 – 167 intestinal yersiniosis cases and 38 extraintestinal yersiniosis cases. In 2015 and 2016 all intestinal yersiniosis cases met the criteria for confirmed case. In turn, among extraintestinal yersiniosis cases in 2015 26 cases met criteria for probable case and 7 for confirmed case and in 2016 – 32 for probable and 6 for confirmed case. Both in 2015 and in 2016 the incidence in mazowieckie voivodeship (1.61/100 000 in 2015 and 1.55/100 000 in 2016) largely exceeded the average incidence in Poland. The overall proportion of hospitalizations, 59.5% in 2015 and 58% in 2016, remained at the level similar to the preceding years. Serotype of the isolated Yersinia enterocolitica in 2015 in Poland was determined in 59 cases (32% of all Y. enterocolitica isolates). In 2016 serotype was determined in 47 cases of Y. enterocolitica infections (27% of all Y. enterocolitica isolates). Predominant serotype was O3. As in the previous years about 1/3 of infections occurred among children aged 0-4 (110 cases, 34.9% in 2015 and 92 cases, 30.9% in 2016). In 2015 there were no yersiniosis outbreaks, in 2016 there was one outbreak caused by Y. enterolitica.

CONCLUSION

Yersiniosis in Poland is rarely diagnosed and is likely underreported. The percentage of serotyped isolates continues to be low.

目的

本研究旨在评估2015年和2016年波兰耶尔森菌病的流行病学情况，并与前几年进行比较。

材料与方法

评估基于对年度公报《波兰的传染病与中毒》（4,5）中的数据、各地区卫生流行病学站发送至国家公共卫生研究所-国家卫生研究院传染病流行病学与监测部的耶尔森菌病个案报告信息、地方卫生流行病学站通过“Rejestr Ognisk Epidemicznych”（传染病爆发电子登记系统）提供的疫情信息以及中央统计局人口研究部的死亡数据的分析。

结果

2015年和2016年波兰登记的耶尔森菌病病例数相同，均为205例，年发病率为0.53/10万。其中，2015年有172例肠道耶尔森菌病病例和33例肠道外耶尔森菌病病例；2016年有167例肠道耶尔森菌病病例和38例肠道外耶尔森菌病病例。2015年和2016年所有肠道耶尔森菌病病例均符合确诊病例标准。而在2015年的肠道外耶尔森菌病病例中，26例符合可能病例标准，7例符合确诊病例标准；2016年，32例符合可能病例标准，6例符合确诊病例标准。2015年和2016年，马佐夫舍省的发病率（2015年为1.61/10万，2016年为1.55/10万）均大大超过波兰的平均发病率。总体住院比例在2015年为59.5%，2016年为58%，与前几年的水平相近。2015年在波兰59例（占所有小肠结肠炎耶尔森菌分离株的32%）中确定了分离出的小肠结肠炎耶尔森菌的血清型。2016年在47例小肠结肠炎耶尔森菌感染病例（占所有小肠结肠炎耶尔森菌分离株的27%）中确定了血清型。主要血清型为O3。与前几年一样，约1/3的感染发生在0至4岁儿童中（2015年110例，占34.9%；2016年92例，占30.9%）。2015年没有耶尔森菌病疫情，2016年有1起因小肠结肠炎耶尔森菌引起的疫情。
