Abstract
Objectives We aimed to describe the current HBV incidence and patterns of transmission in Canada, as well as discussing implications for the control of HBV through immunization. Method We analyzed acute hepatitis B cases reported to the Enhanced Hepatitis Strain Surveillance System during the period 1999–2004 from 7 health sentinel Regions in Canada. Results The incidence of acute hepatitis B per 100,000 population significantly declined, from 2.05 in 1999 to 0.93 in 2004 (p Conclusion The decline of the incidence observed can be attributable to predonation blood screening, promotion of safer sex, and implementation of vaccination. Endemic transmission may be further reduced by improving immunization coverage among certain high risk groups (IDU, MSM, high-risk sexual activity). This continued strategy will dramatically limit the number of acute infections.
