HepVu
While there are treatments available to cure people of hepatitis C, there are roughly 3.9 million people with past or current infections.
HepVu, a new project run by Emory University's Rollins School of Public Health in partnership with the Centers for Disease Control and Prevention and the pharmaceutical company Gilead, maps out which states have the highest prevalence of the disease.
It's the same group that runs AIDSVu, a similar project that has been mapping out HIV by county since 2010 to get a better sense of the epidemic.
