Objective: To assess the incidence of clinically identified hepatitis B cases, as well as the demographic and risk behaviour profiles of these cases in a defined Canadian population.
Methods: An enhanced hepatitis surveillance system was established in October 1998 to identify acute hepatitis B and C cases in Canada. Acute and likely acute cases, as determined by laboratory testing, collectively defined incident clinical hepatitis B cases.
Background: Acute hepatitis B virus (HBV) transmission remains a significant public health problem despite effective vaccination and prophylaxis strategies. Vancouver, British Columbia, has a large ethnic community from endemic areas, which may further impact on the epidemiology of acute HBV. A cross-sectional study of factors associated with acute HBV cases reported to the Vancouver Coastal Health Authority (Vancouver, British Columbia) from 2000 to 2003 is reported.

- * HCV incidence declined by 36.4%, dropping from 3.3 to 2.1 cases per 100,000 population, with the highest rates seen among individuals aged 15 to 39, primarily due to injecting drug use.
- * Despite the decline, hepatitis C continues to pose a significant public health risk, highlighting the need for targeted prevention strategies aimed at injection drug use in the 15 to 39 age group.
