It's always unfortunate to hear that an organ donation recipient ends up having HIV due to the donor being a high-risk donor. Do patients need to do more due diligence before accepting organ donations?

That's a question with high emotional and ethical considerations. But, if a recipient accepted an organ that would continue giving the opportunity to live -- but possibly live with a disease that would be complicated to manage -- some may ask if it's even worth it in the first place.

Although transmission of HIV through organ donation is extremely rare in the U.S. (a recent case in Chicago was the first since 1986), there are still hard questions to answer here. What kind of research would you do if you required an organ donation? Any?
