Hepatitis F is a hypothetical virus linked to viral hepatitis. Several hepatitis F candidates emerged in the 1990s; however, none of these claims were substantiated. [1] [2] [3] In 1994, Niren Deka et al. reported that novel viral particles had been discovered in the stool of post-transfusion, non-hepatitis A, non-hepatitis B, non-hepatitis C ...
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.

Hepatitis D is caused by the hepatitis D virus (HDV), or hepatitis delta virus; it belongs to the genus Deltavirus. HDV is similar to a satellite virus as it can only propagate in the presence of the hepatitis B virus, depending on the helper function of HBV for its replication and expression. It has no independent life cycle, but can survive ...
For the other, roughly 70 percent of people with hepatitis C, the body’s immune system cannot boot the virus out so easily, and eventually, the infection becomes ongoing, or chronic, lasting for ...
Acute hepatitis B; Acute hepatitis C; Acute hepatitis D – this is a superinfection with the delta-agent in a patient already infected with hepatitis B; Acute hepatitis E; Chronic viral hepatitis; Other viral hepatitis viruses may exist but their relation to the disease is not firmly established like the previous ones (hepatitis F, GB virus C ...
In August 2022, 9 children in a U.S. case series of hepatitis of unknown cause [7] and 27 of 30 children in a U.K. case series with hepatitis of unknown cause who underwent molecular testing [8] tested positive for human adenovirus type 41 in a sample. It was unclear whether human adenovirus 41 was the cause, however.
“Nausea and or vomiting are usually the first symptoms of norovirus,” says infectious disease expert Amesh A. Adalja, MD, a senior scholar at the Johns Hopkins Center for Health Security.
