What is Hepatitis C?

Hepatitis C is a viral infection that affects the liver, often causing no noticeable symptoms for years, which means many people don't know they're infected until liver damage has progressed or it's found through testing. It's spread through blood-to-blood contact, historically through blood transfusions before screening was introduced, and now more commonly through shared needles or equipment.

Modern antiviral treatments have transformed the outlook for hepatitis C, curing the infection in the vast majority of people with a relatively short course of tablets, usually 8 to 12 weeks, with minimal side effects.
