In the past, the highest rates of hepatitis A have been found among American Indians/Alaska Natives; however, these rates have dropped since vaccines became available in 1995. Rates of hepatitis B continue to decline among all racial and ethnic groups, but remain highest among non-Hispanic blacks, with 2.9 cases per 100,000 people based on 2005 data. Most hepatitis C cases occur in adults who inject drugs.
