I do think Thomas Duncan was treated fairly. Mistakes were made, to be sure, but who's to say whether those were the result of lies, miscommunications, or simply one of those unfortunate slips that can occur in a busy, high-stress environment like a hospital. I wasn't there and can't judge, but from what I've heard and read, it sounds like every effort was made to treat him as soon as they were aware of his advanced diagnosis.
As far as your question, though, I will say, according to CNN, Mr. Duncan received one of the experimental drugs approved for Ebola. He just didn't receive it as quickly as the others, likely due to the delay in his diagnosis. As far as the blood transfusion goes, I don't know if he received transfusions to treat the blood loss caused by the disease, but that should not be confused with blood transfusions from known ebola survivors, which is a treatment they have been attempting with some of the patients. He did not receive one of those transfusions, according to an article yesterday, because there was no match for his blood type. However, two of the other patients were a blood type match for one of the doctors who survived the virus, and that doctor donated blood for them.
When it comes down to it, I think it's common for people to be angry and confused when a loved one dies in the hospital because there is the sense that those are the experts who should be able to fix things. I think people like to have someone to blame for bad outcomes. (In fact, I remember feeling this way when my sister-in-law died two years ago; it seemed like someone should have been able to do something better or differently.But sometimes their best just isn't enough.)
But as has been pointed out, there is a high death rate with ebola. So far about 3400 people of the 7000 infected have died in Africa. So, it's a tragic and unwanted outcome for Mr. Duncan to die, but not exactly a shock in light of the way the outbreak has progressed, particularly given his direct, close contact with the young lady who he was helping in Liberia (who also died from it, I might add).
