New York -- Two more people have contracted hepatitis C after receiving intravenous anesthesia from a doctor in New York who is under investigation.

Dr. Brian Goldweber, 64, is accused of spreading the disease by failing to follow proper infection control protocols, The New York Post reported Sunday. A 45-year-old woman with a prominent corporate post filed a lawsuit last week against Goldweber and three other doctors at the Manhattan practice, where she underwent a colonoscopy in 2004. She filed her suit as "Jane Doe" due to what she called the "stigma, discrimination and embarrassment" of a hepatitis C infection, which typically affects drug addicts and the sexually promiscuous. Another woman has notified the city Health Department after contracting hepatitis C after an outpatient procedure. That notification brings the number of possible victims to at least five, the Post said. Copyright 2007 by United Press International.
