Hepatitis C in Poland in 2016.

Introduction: In 2016, the World Health Organization implemented a Global Strategy to eliminate viral hepatitis. For Hepatitis C, the goals of this Strategy include increased harm reduction coverage, improved safety of medical procedures and an increase the percentage of people diagnosed and treated.

Objective: This article aims are evaluating the epidemiological situation of HCV infections in Poland in 2016 in reference to the data from previous years.

Material And Methods: Analysis of epidemiological situation of hepatitis C in Poland in 2016 was carried out on case-based data collected through routine surveillance system. Data on hepatitis C mortality from the Demographic Surveys and Labour Market Department of the Central Statistical Office were also included.

Results: In 2016, a total of 4,261 cases were reported. Diagnosis rate was 11.09 per 100,000, on the similar level as in 2015 (1% decrease), but in comparison to the median for the years 2010-2014 it increased by 88%. The most common possible route of HCV infection were medical procedures accounting for 69.8% of all cases and for 58.2% of acute hepatitis C virus infection cases. In 2016, 224 deaths due to hepatitis C were registered. In 2016, a hepatitis C outbreak was reported in małopolskie voivodeship (11 patients of the Hemato-oncolology Department, 129 people exposed).

Conclusions: The increase of HCV diagnosis rate, which has been reported for last three years, is probably a consequence of improved the surveillance, including mandatory reporting of positive laboratory results, but also increased availability of HCV laboratory screening. Medical exposures are still an important route of transmission of HCV in Poland.
