Hepatitis C is an infection of the liver and is the most common blood-borne viral infection in the United States. It can lead to serious liver problems if left untreated. The CDC recommends you get tested if you have shared or used non-sterile needles with an infected person, have unprotected sex with an infected person, have HIV, were born to a mother with hepatitis C, or have symptoms of a liver disease. The only way to know for certain if you have hepatitis C is to get a blood test; visit the John Bell Health Center at 1207 Chestnut St., 3rd Floor to schedule an appointment for testing.
