DEAR DOCTOR K: My son has a hepatitis C infection, based on a blood test. The doctor says he's OK now, but could someday become seriously ill. I hear there are new treatments for hepatitis C. Is there reason for optimism?
DEAR READER: Hepatitis C is caused by a viral infection that inflames and damages the liver. ("Hepatitis" means inflammation of the liver.) The hepatitis C virus (HCV) is usually transmitted through contact with infected blood. HCV can cause short-term (acute) or long-term (chronic) hepatitis C. Most people with acute hepatitis C eventually develop chronic hepatitis C.
