http://sg.news.yahoo.com/fears-11-000-australian-dental-patients-exposed-hiv-012951537.html Up to 11,000 Australian dental patients were urged to see their doctors Thursday over fears they may have been exposed to HIV and hepatitis due to hygiene breaches at clinics in Sydney. New South Wales Health said 12 dentists from four surgeries were accused of poor cleaning and equipment sterilisation practices and advised patients to get blood tests for HIV as well as Hepatitis A, B and C as a precaution. While NSW Health director of health protection Jeremy McAnulty said no cases had been found so far and the risk of transmission was low, there was concern about people who had undergone invasive procedures.
