Health officials have notified more patients at a West Virginia heart clinic who may have been exposed to hepatitis.
Local media outlets report that the West Virginia Department of Health and Human Resources announced Monday that four additional cases of hepatitis C were detected by the state Bureau of Public Health.
In March, the bureau investigated 12 cases of hepatitis linked to injectable medications given during cardiac stress tests at the Raleigh Heart Clinic in Beckley.
State Health Commissioner Dr. Rahul Gupta says the four additional cases were contracted before March 1, 2012.
Officials are urging anyone who may have received a stress test at the clinic prior to that date to be tested for hepatitis B and C as well as HIV.
