Voronezh Oblast's chief doctor, Mikhail Chubirko, said today 208 patients have received albumin injections from a female donor who was HIV-positive.
Chubirko said 70 people have already been identified and will undergo tests in the coming days.
The regional prosecutor's office has opened an investigation into whether doctors at the blood-transfusion center had taken all proper safety precautions.
