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 ...
The prenylation inhibitor lonafarnib prevents hepatitis D viral particle assembly by inhibiting the farnesylation of the L-HDAg. [53] REP2139-Ca is a nucleic acid polymer that prevents the release of hepatitis B surface antigen (which is required for assembly of hepatitis D viral particles). [54]
Viral hepatitis is liver inflammation due to a viral infection. [1] [2] It may present in acute form as a recent infection with relatively rapid onset, or in chronic form, typically progressing from a long-lasting asymptomatic condition up to a decompensated hepatic disease and hepatocellular carcinoma (HCC).
MMWR has its roots in the establishment of the Public Health Service (PHS). On January 3, 1896, the Public Health Service began publishing Public Health Reports.Morbidity and mortality statistics were published in Public Health Reports until January 20, 1950, when they were transferred to a new publication of the PHS National Office of Vital Statistics called the Weekly Morbidity Report.
Hepatitis D is a defective virus that requires hepatitis B to replicate and is only found with hepatitis B co-infection. [17] In adults, hepatitis B infection is most commonly self-limiting, with less than 5% progressing to chronic state, and 20 to 30% of those chronically infected developing cirrhosis or liver cancer.

A satellite virus important to human health that demonstrates the need for co-infection to replicate and infect within a host is the virus that causes hepatitis D. Hepatitis D or delta virus (HDV) was discovered in 1977 by Mario Rizzetto [10] and is differentiated from hepatitis A, B, and C because it requires viral particles from hepatitis B ...
An epidemic curve, also known as an epi curve or epidemiological curve, is a statistical chart used in epidemiology to visualise the onset of a disease outbreak. It can help with the identification of the mode of transmission of the disease. It can also show the disease's magnitude, whether cases are clustered or if there are individual case ...
Hepatitis D virus (HDV) is an example of a replication defective, helper dependent ssRNA virus because it requires Hepatitis B virus (HBV) to provide HBV surface antigen (HBsAg) for the encapsidation of its genome. The envelope proteins on the outer surface of HDV are entirely provided by HBV.
