	HepNet - Acute Viral Hepatitis in the United States
		Viral hepatitis refers to a primary infection of the liver caused by at least five unrelated viruses, and acute and chronic liver disease due to viral hepatitis accounts for substantial morbidity and mortality.
		The three major types of viral hepatitis in the United States are hepatitis A, hepatitis B, and hepatitis C. The serologic exclusion of the known hepatitis viruses continues to leave cases of hepatitis that clinically appear to be viral in origin.
		Had hepatitis B vaccine been routinely administered in STD clinics or prisons, as is recommended, up to one half of all cases of acute hepatitis B could potentially have been prevented.

	Acute Viral Hepatitis: Hepatitis: Merck Manual Professional
		Acute viral hepatitis is diffuse liver inflammation caused by specific hepatotropic viruses that have diverse modes of transmission and epidemiologies.
		Acute HDV infection typically presents as unusually severe acute HBV infection (co-infection), an acute exacerbation in chronic HBV carriers (superinfection), or a relatively aggressive course of chronic HBV infection.
		Fulminant hepatitis is a rare syndrome of massive necrosis of liver parenchyma and a decrease in liver size (acute yellow atrophy) that usually occurs in infection with certain hepatitis viruses or with toxic agents or in drug-induced injury.

	Index \| CDC Viral Hepatitis
		Hepatitis C: is a liver disease caused by the hepatitis C virus (HCV), which is found in the blood of persons who have the disease.
		Hepatitis D: is a liver disease caused by the hepatitis D virus (HDV), a defective virus that needs the hepatitis B virus to exist.
		Hepatitis E: is a liver disease caused by the hepatitis E virus (HEV) transmitted in much the same way as hepatitis A virus.

	HEPATITIS
		Under most circumstances none of the hepatitis viruses is known to directly damage hepatocytes; liver damage and subsequent clinical symptoms associated with acute hepatitis are generally a result of the host’s immune response to infection.
		Acute hepatitis is associated with a characteristic set of symptoms; the symptoms caused by HAV, HBV, and HCV are indistinguishable, except that acute HCV infection is more frequently subclinical.
		Fulminant hepatic failure is defined by the presence of hepatic encephalopathy and severe impairment of liver function (eg, elevated serum bilirubin and prothrombin time with decreasing serum albumin concentrations).

	Chapter 14 - Section 4: First Principles of Gastroenterology
		Hepatitis D infection may originate as a co-infection with hepatitis B or as a superinfection in a patient who is already a chronic HBV carrier.
		Hepatitis E (epidemic hepatitis) appears to be due to a single-stranded RNA virus of 27-34 nm in size.
		This pattern is most characteristic of hepatitis A. In some cases of hepatitis B, the second phase is due to acute hepatitis D. Hepatitis C is characterized by continued and wide fluctuations in liver aminotransferase values, but a biphasic clinical course is uncommon.

	Hepatitis
		Acute viral hepatitis varies from a minor flu-like illness to an overwhelming infection resulting in liver failure and death.
		One trial has suggested that silymarin may be more effective for hepatitis B as opposed to hepatitis C. Recent findings have shown that silymarin has the ability to block fibrosis, a process that contributes to the eventual development of cirrhosis in persons with inflammatory liver conditions secondary to alcohol abuse or hepatitis.
		A series of cases of acute viral hepatitis were reported by one group in India, showing picrorhiza, combined with a variety of minerals, to be helpful in hastening recovery.

	Acute Viral Hepatitis: Hepatitis: Merck Manual Home Edition
		Acute viral hepatitis is inflammation of the liver caused by infection with one of the five hepatitis viruses; for most people, the inflammation begins suddenly and lasts only a few weeks.
		Hepatitis A and C often produce very mild symptoms, or none at all, and may go unnoticed, whereas B and E are more likely to produce severe symptoms.
		A number of other preventive measures against infection with the hepatitis viruses can be taken, such as washing the hands thoroughly before handling food, refraining from high-risk behavior such as sharing needles to inject illicit drugs and having unprotected sex, and avoiding blood transfusions except when absolutely essential.

	Viral Hepatitis Symptoms, Causes, Diagnosis, and Treatment by MedicineNet.com
		If the liver is injured (as in viral hepatitis), the liver cells spill the enzymes into the blood, raising the enzyme levels in the blood and signaling that the liver is damaged.
		Since most patients with chronic hepatitis are asymptomatic (no jaundice or nausea), their mildly abnormal liver enzymes are often unexpectedly encountered on routine blood screening tests during yearly physicals or insurance physicals.
		In acute viral hepatitis, antibodies not only help to eradicate the virus, but they also protect the patient from future infections by the same virus, that is the patient develops immunity.

	Hepatitis
		Although hepatitis C can be spread from a mother to her fetus during pregnancy, the risk of passing hepatitis C to the fetus isn't very high (about 5%).
		Hepatitis A is usually active for a short period of time and once a person recovers, he or she can no longer pass the virus to other people.
		People with hepatitis B (the percentage who don't recover completely) or hepatitis C who continue to be infected can go on to develop chronic hepatitis and cirrhosis of the liver (the chronic degeneration and disruption of the structure of the liver).

		Hepatitis B is targeted by WHO for reduced incidence/prevalence, by means of vaccination programs in children under 1 year of age.
		Understanding the epidemiology and impact of viral hepatitis requires enhanced surveillance and an understanding of the sequelae of hepatitis B, C and D virus infection, such as asymptomatic chronic infection, chronic hepatitis, cirrhosis, and primary liver cancer.
		Hepatitis vaccine is given to infants (less than one year) (and in some industrial countries to adolescents), and to special groups such as health workers, primarily to prevent the development of chronic liver disease and liver cancer.
