This happened at the state-run hospital at Candos back in 2015. The reason is that the blood was contaminated with various diseases. Positive tests showed that the blood was contaminated with various diseases such as Hepatitis C, Syphilis, with others linked to HIV.
It is comforting to note that the hospital laboratory is doing analysis safety checks on blood donations. However, we wonder how it is possible for people to give blood when they presumably know they are infected ? Or, is part of the answer that some donors are not aware that they have contracted a disease ? This situation is mind-blowing and alarming.
