How long can Hepitities B,C & HIV Viruses survive in a contaminated blood transfusion sack collected from an?
Question:
Answers:
The viruses would remain viable until the unit is destroyed. Most likely the unit would test positive for the presence of these viruses shortly after the donation and then placed in a biohazard container and destroyed. In the US, the tests to detect the presence of these viruses are highly sensitive and reliable and if I needed a blood transfusion today or I would die, then I would definitely trust our blood supply to be safe. There is always a risk of getting something from a blood transfusion - because there is nothing that is 100% guaranteed - but the greatest risk is currently getting the wrong unit of blood (wrong blood type!).
The best information I have found on this is that if the blood is frozen, these viruses can survive for years if properly preserved.
