I'm talking about lost productivity and that maybe a billion are affected each year. Heart disease is both a genetic and a lifestyle issue, it's much harder to tackle than creating an anti-viral medicine.
So does heart disease. You're somehow ignoring the "lost productivity" of 6.5 million people per year dying! And I didn't mention stroke, respiratory diseases, AIDS, and non-flu intestinal diseases, each of which kills more people per year than the flu.
