40,000 to be notified in Vegas hepatitis scare

LAS VEGAS SUN

LAS VEGAS — The campaign to notify 40,000 patients of a Las Vegas endoscopy and colonoscopy clinic that they might have been exposed to hepatitis B, hepatitis C or HIV is believed to be unprecedented in U.S. history, according to the Centers for Disease Control and Prevention.

So far, six people have been diagnosed with hepatitis C after undergoing procedures at the Endoscopy Center of Southern Nevada, according to the Southern Nevada Health District.

Previously, the largest campaign to notify patients of possible exposure to hepatitis had been in Brooklyn, N.Y., in 2001. Health officials there had tried to notify more than 2,000 patients who had gastrointestinal exams at a medical clinic after eight patients tested positive for hepatitis C.

Seven of the infected patients had been hospitalized, alerting authorities to the outbreak. The source of the infection was never pinpointed.

Since 1999 the CDC has tracked 31 outbreaks of hepatitis C.

The largest outbreak of hepatitis C in North America — affecting 99 patients — was confirmed in 2002 in connection with an eastern Nebraska cancer clinic.
