I agree with Tegan on the handwashing thing.
On the other hand I have first hand experience on collecting and processing donated blood (used to work for the Red Cross). It is
common practice (although not always done) to "UV" the blood.
Bacteria is killed by the flood of UV rays. Virus are another story
though. The donor in this case was not confirmed to have had the
same bacteria as the people who recieved the blood. This therefor cannot be directly traced back to the boa although it can be indirectly. The patients could have just as easily contracted the
bacteria from a nurse or doctor who owned a boa and didnt follow sanitary practices , ???
I wouldnt put much into the article.
God Bless!
