The hepatitis B viruses cannot be spread by holding hands, sharing eating utensils, kissing, hugging, coughing, sneezing, or breastfeeding. [5] The infection can be diagnosed 30 to 60 days after exposure. [4] The diagnosis is usually confirmed by testing the blood for parts of the virus and for antibodies against the virus. [4]
Hepatitis B virus is more prominently found in US citizens of Asian, Pacific Islander, or African descent and roughly 25% of these individuals will receive a diagnosis. [73] HBV is spread more readily in groups with high risk behavior such as Intravenous drug use, multiple sex partners, and men who have sex with men.
Hepatitis A and E are mainly spread by contaminated food and water. [3] Hepatitis B is mainly sexually transmitted, but may also be passed from mother to baby during pregnancy or childbirth and spread through infected blood. [3] Hepatitis C is commonly spread through infected blood such as may occur during needle sharing by intravenous drug ...

FibroTest has been evaluated in relation to liver biopsy (the current reference standard in liver disease assessment) in people with hepatitis C, hepatitis B, [1] alcoholic liver disease, [2] and non-alcoholic fatty liver disease. [3] They are most useful for cirrhosis and less useful for other stages of liver disease. [4]
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).
Seroconversion plays a major role in the diagnosis and treatment of hepatitis B infections. [60] As in other viral infections, seropositivity indicates that an individual has a sufficiently high concentration of antibody or antigen in the blood to be detectable by standard techniques.
The list of conditions associated with chronic liver disease is extensive and can be categorised in the following way: [3]. Viral causes. Hepatitis B; Hepatitis C; Cytomegalovirus (CMV), Epstein Barr virus (EBV), and yellow fever viruses cause acute hepatitis.
