Much mystery surrounds the Hepatitis C virus-also known as HCV. Millions of Americans are infected by HCV- but the truth is many don't know it. Their exposure could have come many years ago-when they were in college, or in the military-or through a blood transfusion. In this program, we speak to experts who research and understand the disease along with patients who have lived with it, as we discover more about this potentially life-threatening virus. We'll also take a look at some of the breakthroughs that have occurred only in the past few years that are changing the face of how this virus is treated,-and how that affects the lives of its victims.
