The National African American Hepatitis C Action Day (NAAHCAD) campaign is a community mobilization initiative aimed at reducing the high incidence of HCV infection in black communities by drawing attention to this neglected health disparity and promoting education, testing, and treatment. People in communities of color are encouraged to visit testing centers and be screened for HCV infection—a silent killer that, if left undetected, can lead to life-threatening liver disease, including liver cancer.
