As I understand it, there was an extremely high mortality rate among hemophiliacs during a certain time period in the 1980's before blood was routinely screened for HIV.
The statement "in the USA" should be included in the above, in addition concerns about the mortality rate being not just extremely high, but close to 100% should have been mentioned. No proof of mortality rate, just one of those, "I read it somewhere".
The mortality rate is highest amongst the Factor 8 Hemopheliacs. My son, thankfully is a Factor 9 but he is positive for Hep C anyway. The Factor 8's - up to 80% of them were co-infected with both HIV & Hep C!! A total travesty for sure.
