Since 1997, hepatitis C (HCV infection) is registered separately in epidemiological surveillance in Poland. Having considered the predominance of chronic infections of long-term asymptomatic course, the number of infections detected in successive years and registered in surveillance system does not reflect the actual dynamics of hepatitis C epidemiological situation. To a large extent, it is dependent on current HCV testing practices. Furthermore, it may also result from modifications introduced to the regulations of HCV case notification.
This article aims at evaluating the epidemiological situation of hepatitis C in Poland in 2013 with the reference to the data from previous years.
Epidemiological situation of hepatitis C in Poland was analyzed on a basis of aggregated data from routine surveillance system published in annual bulletin "Infectious diseases and poisonings in Poland in 2013"(Czarkowski MP et al. Warsaw: NIPH-NIH and CSI, 2013). Data on hepatitis C mortality was derived from the Demographic Surveys and Labour Market Department of the Central Statistical Office.
In 2013, a total of 2,705 (incidence 7.03 per 100,000) HCV infections meeting 2005 definition were reported in Poland, including 35 co-infections with HCV and HBV (1.3%). Having compared to 2012, there was an increase in incidence by 15% (2,359; 6.12). In 2013, 2,641 cases (6,86) meeting 2009 definition were registered. Compared to 2012, it was an increase by 16% (2,268; 5.89). In 2013, 175 HCV fatal cases were reported, of whom only 2 were due to the acute stage of disease.
In recent years, a societal burden resulting from undiagnosed or untreated chronic HCV infections is on the increase. It is demonstrated by high HCV mortality and increasing trend of incidence of symptomatic chronic hepatitis C (2005 definition) and hospitalizations.
自1997年起,丙型肝炎(丙肝病毒感染)在波兰的流行病学监测中单独登记。鉴于长期无症状慢性感染占主导,连续数年在监测系统中检测到并登记的感染病例数并未反映丙型肝炎流行病学情况的实际动态。这在很大程度上取决于当前的丙肝病毒检测实践。此外,这也可能源于丙肝病例通报法规的修改。
本文旨在参照往年数据评估2013年波兰丙型肝炎的流行病学情况。
基于年度公报《2013年波兰的传染病与中毒》(Czarkowski MP等人。华沙:国家公共卫生研究所-国家卫生研究院和中央统计局,2013年)中常规监测系统的汇总数据,分析波兰丙型肝炎的流行病学情况。丙型肝炎死亡率数据源自中央统计局人口统计与劳动力市场部。
2013年,波兰共报告了2705例符合2005年定义的丙肝病毒感染病例(发病率为每10万人7.03例),其中35例为丙肝病毒与乙肝病毒合并感染(1.3%)。与2012年相比,发病率上升了15%(2359例;6.12)。2013年,登记了2641例符合2009年定义的病例(6.86)。与2012年相比,增长了16%(2268例;5.89)。2013年报告了175例丙肝死亡病例,其中仅2例死于疾病急性期。
近年来,未诊断或未治疗的慢性丙肝病毒感染所带来的社会负担不断增加。这表现为丙肝高死亡率以及有症状慢性丙型肝炎(2005年定义)发病率和住院率的上升趋势。
