CDC: Syringe Reuse Linked to Hepatitis C Outbreak

A hepatitis C
outbreak was caused by workers improperly reusing syringes
and medicine vials at a Las Vegas clinic, federal health
officials said Friday.
The Centers for
Disease Control and Prevention was contacted by state
health officials earlier this year after two people treated
at the now-closed Endoscopy Center of Southern Nevada

sedative was needed. Backflow into the syringe from an
infected patient could have contaminated the sedative
vial. The virus could have been passed along from the
contaminated vial when it was improperly used for the
next patient, the CDC said.
About 400 former
patients of the center tested positive for hepatitis C
but officials have determined that most could have
contracted the virus through other means, including
intravenous drug use, blood transfusions, organ
transplants or kidney dialysis, receiving blood clotting
agents before 1987, or sexual contact with a person
with hepatitis C.

pain, fatigue and jaundice. It may eventually result in
liver failure. Even when no symptoms occur, the virus
can slowly damage the liver.

licenses have been suspended pending state Board of
Medical Examiners hearings.
Las Vegas police
have seized medical records from the clinics, and the
FBI, the state attorney general and the Clark County
district attorney are involved in a criminal
investigation. The owners of the clinics have
surrendered business licenses and paid $500,000 in fines.
