    HDV RNA is a single-stranded circle, with a high degree of self-complementarity and G+C content causing the circle to collapse as a rod-like structure Significant sequence heterogeneity (as high as 40 percent) exists among the different HDV isolates that have been sequenced, and a classification into eight HDV genotypes has been proposed
  • Hepatitis D - Wikipedia
    Hepatitis D is a type of viral hepatitis [3] caused by the hepatitis delta virus (HDV) rod-like RNA structure [17] Worldwide prevalence of HDV among HBV carriers in 2015 Eight genotypes have been identified worldwide by comparative phylogenetic analysis Genotype 1 is the most frequent and has variable pathogenicity, Genotypes 2 and

  • Hepatitis D: A Review | Hepatobiliary Disease - JAMA Network
    HDV interferes with HBV replication 25 Therefore, most patients with chronic hepatitis D have low serum HBV-DNA levels 26 Nevertheless, chronic hepatitis D has an accelerated course with more rapid progression to cirrhosis, and a higher incidence of liver-related mortality and hepatocellular carcinoma than chronic hepatitis B infection alone

  • Hepatitis D Virus 2025 Case Definition | CDC
    HDV infection, often referred to as hepatitis D, can cause severe liver damage and even death among persons living with hepatitis B virus (HBV) infection HDV infection in the United States (U S ) is believed to be rare, but due to limited and non-uniform testing and reporting practices, the exact burden of HDV infection is unknown
  • Epidemiology of hepatitis D - Wikipedia
    The epidemiology of hepatitis D occurs worldwide [1] Although the figures are disputed, a recent systematic review suggests that up to 60 million individuals could be infected [ 2 ] The major victims are the carriers of the hepatitis B surface antigen ( HBsAg ), who become superinfected by the HDV, and intravenous drug users who are the group
  • Hepatitis D - World Health Organization (WHO)
