 And then about 40% of infected Americans don't know they have hepatitis C. Hepatitis C is a virus that can cause liver cancer, and you wouldn't even know it. I mean, you could be sitting there infected for years and not know that you have it. And it's easily curable with a pill that has very few side effects that you take for eight to 12 weeks. So they don't know they have it because they haven't had a simple screening blood test, which the CDC suggests for all adults, all people over the age of 18, at least once in your life. So these are very bottom, low-lying fruit for people.
