[ . I recall reading that most of the 4 million infected with HCV in the U.S. are unaware they have the virus. ]
If the infected are not aware they have been infected , how and who know they are infected ? That does not make any sense. No one is going to see doctor and ask to be examined unless they have syntom of the disease. I wonder if bribery somewhere along the line may not be involved in this buy out decision.
I believe we are going to see screening tests for HCV being recommend not just for high risk individuals, but most of us born between 1946 and 1964 (the baby boom generation -- that happens to have the highest number of HCV cases).
Even high risk people do not go for check up for well publicized HIV, never mind HCV. Mind you, HCV was cloned in the early 80s at Chiron, and it has been around for 30 years. How many large scale screening have we had ?
