At least 20 million Hepatitis B Virus (HBV), 2.0 million Hepatitis C Virus (HCV) and 0.26 million HIV new infections are associated with unsafe use of injections every year across the world, experts quoting a WHO report said yesterday. They also warned that South East Asia is a red zone of unsafe use of injections, saying that half of the total use of injections in the world is unsafe. Experts said this yesterday at a seminar on 'Injection use and risk of HBV, HCV and HIV infection: Intervention for risk reduction' at the British Council auditorium in the city.
