Two more Nevada clinics were shut down Wednesday after the medical group that operates them was accused of infecting people with the hepatitis C virus.
The closure of Gastroenterology Center of Nevada offices in Henderson and North Las Vegas leaves just one clinic associated with the company still open. That clinic is located on Tenaya Way in Las Vegas.
The Southern Nevada Health District says some 40,000 former patients of the group's Endoscopy Center of Southern Nevada on Shadow Lane are at risk of hepatitis C, B and HIV, the virus that causes AIDS.
They received treatment at the clinic between March 2004 and last Jan. 11.
Center owners can appeal Tuesday's orders to shut down the clinics to the Henderson and North Las Vegas city councils.
City, county, state and federal agencies are investigating amid allegations that injection practices, including reuse of syringes and vaccines, exposed patients to potentially deadly infections.
