A Las Vegas clinic was found to have reused syringes and medical vials, putting 40,000 patients at risk for hepatitis and HIV. 

Health officials said in a statement that patients who received anesthesia injections at the Endoscopy Center of Southern Nevada between March 2004 and January 11, 2008 are currently being notified and asked to contact their general practitioner for hepatitis B, hepatitis C and HIV testing.

According to AFP, the clinic issued a statement claiming that it has already taken the necessary steps to correct the problem.

“As always, our patients remain our primary responsibility and we have already corrected the situation,” clinic officials say. “We have already taken steps to ensure that it will never happen again…We want to be sure that every patient who may have been exposed is informed and tested.”
