Officials have investigated at least 12 cases of hepatitis linked to a heart clinic in Beckley.
The viruses have been linked to injectable medications given during cardiac stress tests at the Raleigh Heart Clinic.
Department of Health and Human Resources Director of Communications Allison Adler says that eight patients receiving cardiac stress tests have tested positive for hepatitis C and four others have tested positive for hepatitis B. There has not been any evidence of HIV transmission.
State Health Commissioner Dr. Rahul Gupta says the extent of how many individuals were exposed to the pathogens is unknown. Officials are now urging about 2,300 patients of the Raleigh Heart Clinic to be tested for hepatitis B and C as well as HIV.
