Prevalence data from sources such as population surveys can be a useful complement to case based surveillance data for hepatitis C. Case-based surveillance has limitations as most diagnosed cases are chronic in nature and detection of cases depends largely on testing practices. Prevalence data can therefore contribute towards a fuller understanding of the epidemiology of hepatitis C.
This issue of the ECDC Communicable Disease Threats Report (CDTR) covers the period 7-13 May 2023 and includes updates on measles, COVID-19, influenza and swine influenza, group A Streptococcal infection, Marburg virus disease, Lassa fever, diphtheria and mpox.
In 2021, 14 560 cases of hepatitis C were reported in 29 EU/EEA Member States. Excluding countries that only reported acute cases the number of cases (14 550 cases) corresponds to a crude rate of 4.1 cases per 100 000 population.
Viral hepatitis is an infection that causes inflammation of the liver. It can be caused by different viruses, including hepatitis B virus (HBV) and hepatitis C virus (HCV). Both HBV and HCV can cause acute and chronic infections and are leading causes of liver cirrhosis and hepatocellular carcinoma.
