Hepatitis is an inflammation of the liver, which can lead to fibrosis (scarring), cirrhosis or liver cancer.
There are 5 main hepatitis viruses, referred to as types A, B, C, D and E.
Hepatitis C is mostly transmitted through exposure to infective blood. This can occur through blood transfusions, contaminated injections during medical procedures, and through injecting drugs. Sexual transmission is also possible, but is much less common.
People infected with hepatitis C experience few or no symptoms, meaning they can live with the virus for years without being diagnosed. This delay in treatment can increase the risk of significant liver damage.
There are an estimated 170 million carriers of Hepatitis C around the world.
The virus causes approximately 399,000 fatalities each year worldwide, according to WHO.
