Figure 1: Estimated prevalence of chronic HCV infection (per 100 population) in Canada from a back-calculation model
The prevalence of CHC per 100 population is estimated from the back-calculation model, stratifying data to every 5-year birth cohort according to the year of birth. Each birth cohort is a demographically defined population. The overall CHC prevalence, approximately 0.64%, is estimated regardless of age and year of birth. CHC prevalence in persons born before 1949 has declined from approximately 1% to below the overall prevalence in the past 20 years. Persons born after 1965 show a trend of an increasing CHC prevalence reaching from below the overall prevalence to above it. CHC prevalence in persons born between 1950 and 1964 remained above the overall prevalence throughout the 20 year period.

Figure 3: Phylogentic tree based on Hepatitis C virus E1 gene
Phylogenetic tree demonstrates the genetic relatedness of different Hepatitis C virus isolates. Sequences on the same vertical line are identical. The length of horizontal lines separating sequences or branches of sequences is proportional to the number of differences (measured in single nucleotides) between the sequences. There are red dots on 13 among over 40 different nucleotide sequences that, when present in different specimens, indicate statistically plausible transmission from the same source.
