Next Friday, July 28, is World Hepatitis Day.

Four-hundred million people are living with hepatitis B or C.

Every year 1.4 million people die from viral hepatitis; yet all of these deaths could be prevented.

The Prevent Cancer Foundation's Think About the Link campaign aims to increase the vaccination rate to prevent Hep B and raise awareness of and access to available treatment options for Hep C.

With better awareness of how we can prevent hepatitis - we can eliminate this disease and save 4,000 lives a day.
