Hepatitis C is a viral infection that causes liver inflammation, sometimes leading to serious liver damage. The hepatitis C virus (HCV) spreads through contaminated blood.
Until recently, hepatitis C treatment required weekly injections and oral medications that many HCV-infected people couldn’t take because of other health problems or unacceptable side effects.
That’s changing. Today, chronic HCV is usually curable with oral medications taken every day for two to six months.
Still, about half of people with HCV don’t know they’re infected, mainly because they have no symptoms, which can take decades to appear. For that reason, the Centers for Disease Control and Prevention recommends a one-time screening blood test for everyone at increased risk of the infection. The largest group at risk includes everyone born between 1945 and 1965 — a population five times more likely to be infected than those born in other years.
