Hepatitis C

Hepatitis C virus (HCV) represents a public health challenge.
In Belgium, 18,000 people are infected with HCV and as many as 300 patients die each year as a result of their infection.(1,2)
Data shows that in 2020 there were 11.0 (9.5-12.5) million viremic HCV infections worldwide, corresponding to a prevalence of 1.2% (1.0-1.3%).(3)
In 2016, the World Health Organization (WHO) recognized HCV as a public health threat, and in parallel, set the goal of eliminating HCV by 2030.(4)
In order for Belgium to reach the WHO elimination targets, it has been calculated that approximately 1.200 people would need to be treated per year.(2)

Hepatitis B

Hepatitis B virus (HBV) is one of the most common infectious diseases worldwide.(6)
In 2015, an estimated 257 million people (3.5%) of the world's population were living with chronic HBV infection. Of these, 15 million or 1.6% lived in the European region.(7-10)
The main hepatic complications of chronic HBV infection are cirrhosis, liver failure and hepatocellular carcinoma (HCC). Moreover data suggest that:(10,11)
- HBV is the leading cause of HCC worldwide.
- without adequate monitoring and treatment, up to 1 in 4 people with chronic HBV infection will die of HCC or liver failure.

Hepatitis Delta

Hepatitis Delta infection is caused by the hepatitis D virus (HDV) and is considered the most dangerous hepatitis virus. HDV is dependent on the hepatitis B virus (HBV) and therefore occurs only in people infected with HBV. It can be transmitted through blood, or contact with other bodily fluids such as semen, vaginal fluid, or saliva from an infected person.(13,14)
The worldwide prevalence of HDV infection ranges from 4.5% to 13% in HBsAg+ patients, representing 12 to 60 million infected individuals.(14)
The estimated prevalence varies considerably between countries and analyses. Therefore, the true prevalence of HDV worldwide is unknown and likely underestimated.(15,16)
HDV causes the most severe form of disease among viral hepatitis, increasing the risk of hepatic decompensation, hepatocellular carcinoma, the need for liver transplantation or death from hepatic causes when compared with HBV mono-infection.(13)
