British researchers have found that genotype 1 is the most prevalent hepatitis C virus (HCV) worldwide, with more than 83 million patients infected by the virus, with genotype 3 in the second place followed by genotypes 2, 4, 6, and 5, a new study published in the journal Hepatology reveals.
Despite efforts to control HCV, it remains one of the most prevalent diseases globally, with up to 150 million patients living with chronic infection according to the World Health Organization (WHO). Previous research shows that chronic HCV leads to the development liver cirrhosis, hepatocellular carcinoma (HCC) or liver cancer, liver failure and death. WHO reports that 350,000 to 500,000 deaths each year are caused by liver diseases related to HCV.
