La seconda é la sovrainfezione di virus D in un portatore cronico di HBV. Si verifica a questo punto una nuova epatite acuta a volte fatale. Studi recenti hanno dimostrato che, in Europa e in Usa, il 25-50% dei casi di Epatite fulminante che si pensavano associati al virus dell’ Epatite B , erano invece causati da HDV.
In entrambi i casi l’infezione può diventare cronica e in questo caso ha generalmente un decorso più severo rispetto a quella da virus B.

MODE OF TRANSMISSION: mode of transmission is the same as' Hepatitis B and the incubation period ranges from 2 to 8 weeks.
were identified three genotypes of HDV. The genotype is the most common, genotype II was detected in Japan and Taiwan, while genotype III is present only in the Amazon.
