A man in his 60s contracted HIV after receiving blood donated by an infected man that slipped through safety checks by the Japan Red Cross Society, the health ministry and the Red Cross said Tuesday.

It is the first time since 2003 that someone has been found to have been infected with the virus apparently via a blood transfusion.

Health minister Norihisa Taumra confirmed earlier in the day that blood donated by an HIV-positive man in his 40s that slipped through safety checks was used in two transfusions at separate medical institutions. Officials are trying to determine if the other recipient got the virus.
