Waqas,12, who contracted HIV through a tainted blood transfusion, walks down a flight of stairs with his father after an interview with Reuters in Islamabad December 5, 2014. Lax oversight of blood banks means about a fifth of patients in Pakistan who get regular transfusions have been infected with hepatitis, a top government health official said on Friday. Some also get HIV. Pakistan's dangerously unregulated blood banks are in the spotlight after a charitable federation said 10 children getting transfusions for a blood disease contracted HIV.
