So far, eight genotypes (HDV‐1 to ‐8) have been individualized worldwide. Little is known about HDV strains that spread in Nigeria. HDV genotyping was performed in 15 anti–HDV positive samples from a cohort of 306 hepatitis B virus (HBV)‐infected patients in Abuja (Nigeria). Phylogenetic analyses revealed 90% were HDV‐1, two among them clustering with European/Asian HDV‐1, the remaining one being HDV‐6. It was also found that two members of a couple superinfected with the same HDV strain, were enveloped by two different HBV strains of genotype E.enBloodEpidemiologyHepatitis B VirusHepatitis D VirusSatelliteSubviral AgentsVirus ClassificationArticle
