Couple of thoughts on this topic:
1. spreading the news ww is one parameter which is time consuming, having trust that generics do works is the 2nd parameter.
2. Barriers: Big pharma, perhaps NHS from each country, doctors not being informed about generics from India, patients not knowing there exist the cure.
3. Further barriers: distrust of patients/doctors that generics do work; place of manufacturing - low income countries (India, Bangladesh, Egypt,etc) do raise the level of distrust; sourcing possibilities: fear of getting fake medication due to scams.
4. and further barriers: literacy of patients (medical knowledge as well as english knowledge), IT resources (computer, internet, skills to search on internet)
Looking at the barriers from above, I believe this explains somehow why spreading the news will take some time. Sad that in all this time more people will die of HCV.....
