This could have been imported from Europe during the colonial times to north Africa or the Europeans could have imported it from north Africa. This idea is further confirmed by the recently reported migrations from west Africa to south Africa for employment and education125. In conclusion, our systematic review and meta-analysis has provided an updated literature on the current epidemiology of hepatitis B virus genotypes, sub-genotypes, mixed genotypes and recombinant genotypes on the African continent. Secondly, there is scant published work on the prevalence of HBV genotypes, sub genotypes, genotypes mixtures and recombinant genotypes in Africa to give robust data for satisfactory conclusions to be drawn. Thirdly, Sub genotypes determination requires whole genome sequencing to resolve the sub genotype.
