Figure 1 HCV genotype incidence from 1999 to 2006. The genotypes are indicated in the bars by different shades of grey, representing from bottom to top, genotypes 1, 2, 3, 4 and 5. Number of cases and percentages are mentioned for genotype 1 and 3. No significant changes in genotype distribution over time have been observed during this 7 years period.

Figure 2 Distribution of HCV genotypes. A: Distribution of HCV genotypes in patients according to gender. Genotype 3 is more frequent in male (P < 0.0001), genotype 2 and genotype 5 are more frequent in female (P = 0.047 and P = 0.0027 respectively); B: Distribution of HCV genotypes in patients according to age.
