We analyzed trends in disease incidence and patterns of hepatitis B virus HBV transmission in both Canadian-born and non-Canadian-born children from 1999 to 2003 through the Enhanced Hepatitis Strain Surveillance System. Amongst Canadian-born children the incidence of newly identified HBV infection per 100 000 declined significantly during the study period from in 1999 to in 2003 RR per year 95 CI . Amongst non-Canadian-born children the .
