Figure 3

Figure 3. . Distribution of hepatitis B virus A subgenotypes and D4 (only in Rwanda) in Africa and their potential routes of spread toward Haiti (color-coded arrows). Colored dots indicate African countries with <10 A strains available; full color indicates countries with >90% dominance of 1 subgenotype; or a 60%–90% predominance of 1 subgenotype, with minority subgenotypes shown as diamonds. Subgenotypes other than A1 and D4 are not shown for Rwanda. Sequences included were obtained from GenBank and unpublished data.
