INTRODUCTION: 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. OBJECTIVE: This article aims at evaluating the epidemiological situation of hepatitis C in Poland in 2013 with the reference to the data from previous years. MATERIALAND METHODS: 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. RESULTS: 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. CONCLUSIONS: 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.
