Key facts about Hepatitis C
An estimated 71 million people are chronically infected with the hepatitis C virus (HCV) worldwide and each year between 400,000 and 700,000 deaths are attributable to this virus. In its 2016-2021 Global Hepatitis plan, the WHO defined ambitious strategies to achieve 90% reduction in new HCV cases and 65% decrease in HCV-related mortality by 2030.
In Africa, HCV is mainly transmitted through unsafe medical procedures as illustrated in Egypt, which has the highest national prevalence (15%) of HCV following a large control campaign using intravenous tartar emetic, the standard treatment for schistosomiasis, from the 1950s until the 1980s. This commendable effort to control a major health problem unfortunately established a very large reservoir of HCV in the country.
The injection of drugs is a major cause of HCV spread worldwide. The WHO has identified people who inject drugs (PWID) as a key population to target for HCV screening, prevention and care. It is estimated that 10 million of 16 million PWID across the world are positive for the HCV antibody. HCV is often transmitted through nosocomial routes in Africa. However, intravenous drug use has emerged as a new concern especially in East Africa. East Africa is a point of geographical significance and is widely considered the gateway for African narco-trafficking, with 90% of the imported heroin destined for distribution to both continental and global sites.
