A number of hepatitis viruses have been newly identified belonging to the family hepatitis A-E, by their genome structure. The authors summarize and briefly demonstrate the most important molecular and epidemiological characteristics of te hepatitis GB and G viruses, and they discuss their clinical significance. They discuss the similarities and differences recording the three GB (GB-A, GB-B, GB-C) viruses, and also stress the high rate of similarity between the GB-C and G viruses. All the three GB viruses and G virus have RNA-genome, all of them are transferable with blood and blood preparates, they have been found both in acute and chronic hepatitis. They occur with higher rate in high risk population where the frequency of hepatitis B and C also increased.

UI	MeSH Term	Description	Entries
D005060	Europe	The continent north of AFRICA, west of ASIA and east of the ATLANTIC OCEAN.	Northern Europe,Southern Europe,Western Europe
D006509	Hepatitis B	INFLAMMATION of the LIVER in humans caused by a member of the ORTHOHEPADNAVIRUS genus, HEPATITIS B VIRUS. It is primarily transmitted by parenteral exposure, such as transfusion of contaminated blood or blood products, but can also be transmitted via sexual or intimate personal contact.	Hepatitis B Virus Infection
D006521	Hepatitis, Chronic	INFLAMMATION of the LIVER with ongoing hepatocellular injury for 6 months or more, characterized by NECROSIS of HEPATOCYTES and inflammatory cell (LEUKOCYTES) infiltration. Chronic hepatitis can be caused by viruses, medications, autoimmune diseases, and other unknown factors.

D006525	Hepatitis, Viral, Human	INFLAMMATION of the LIVER in humans due to infection by VIRUSES. There are several significant types of human viral hepatitis with infection caused by enteric-transmission (HEPATITIS A; HEPATITIS E) or blood transfusion (HEPATITIS B; HEPATITIS C; and HEPATITIS D).

D006526	Hepatitis C	INFLAMMATION of the LIVER in humans caused by HEPATITIS C VIRUS, a single-stranded RNA virus. Its incubation period is 30-90 days. Hepatitis C is transmitted primarily by contaminated blood parenterally and is often associated with transfusion and intravenous drug abuse. However, in a significant number of cases, the source of hepatitis C infection is unknown.
