The Centers for Disease Control and Prevention (CDC) is recommending that baby boomers get a one-time blood test for the hepatitis C virus. The CDC notes that more than 15,000 Americans die from hepatitis C-related diseases annually, and that number is growing. With baby boomers making up two-thirds of the estimated 3.2 million infected nationally, the CDC suggests that all older Americans be tested because it can take decades before the virus manifests symptoms in the body.
