Absolutely. Possibly millions of people were exposed to HCV through the blood supply before 1992, and many still don&#x27;t know they were infected.  Since HCV may take 20-30 years to show symptoms, it is a potential public health time bomb. We luckily have a tool to defuse it.<p>For example, essentially every hemophiliac was infected with HCV due to dependence on clotting factor, many also with an HIV co-infection.  80% develop chronic liver disease.<p>Those populations aside, &quot;youthful indiscretions&quot; or even chronic addiction are not reasons for (potential) death sentences due to lack of effective treatment.
