Viral hepatitis is an inflammatory liver condition that most commonly arises from hepatitis A virus (HAV), hepatitis B virus (HBV), hepatitis C virus (HCV), hepatitis D virus (HDV), and hepatitis E virus (HEV). The prevalence of these viruses varies geographically.
Presentation
The clinical picture of acute viral hepatitis is variable and is dependent on the type of the virus and the individual circumstances [1]. This is often a self-limiting disease as a majority of patients will exhibit no/mild symptoms [2]. However, a few may develop a rapid onset of fulminant liver failure.
There are 4 phases of viral hepatitis. In the viral replication stage, the infection is not clinically apparent although the serology is positive. This is followed by the prodromal period, which is characterized by acute manifestations such as fatigue, malaise, fever, anorexia, nausea, emesis, abdominal pain, urticaria, and arthralgia. In the icteric phase, the patients develop jaundice, gastrointestinal disturbance, dark urine, gray-colored stools, right upper quadrant pain, and hepatomegaly. Finally, recovery of the symptoms and liver enzymes occurs in the convalescence stage.
Complications
Patients with HBV and HCV can cause chronic infection, cirrhosis, and hepatocellular carcinoma [3].
Physical exam
Assessment of the patient may yield remarkable findings such as jaundice, scleral icterus, and an enlarged and tender liver.

Workup
The workup consists of the assessment of the clinical presentation, history and risk factors, physical examination, and the pertinent tests.
Laboratory tests
Patients suspected to have viral hepatitis should undergo serology studies to determine the presence of antibodies to the virus. Interpretation of serology markers takes into account differentiation between acute and chronic infection as well as what constitutes an immune status. Also, the clinician must consider the window period for the specific viral subtypes.
An acute infection with HAV is associated with immunoglobulin M (IgM) anti-HAV antibodies [4], which persists for a few months whereas immunoglobulin G (IgG) antibodies reflect a history of infection.
Hepatitis B
Diagnosis of hepatitis B is based on numerous markers. An acute infection is represented by the detection of HBsAg, anti-HBc (total- IgM and IgG antibodies), IgM anti-HBc, and negative anti-HBs [5].
Chronic hepatitis B infection is characterized by the presence of HBsAg that has persisted for more than 6 months [4], positive anti-HBc (total), and negative IgM anti-HBc and anti-HBs [5]. Also, HBV DNA levels are increased [6]. Additionally, alanine transaminase (ALT) and aspartate transaminase (AST) levels are consistently or intermittently elevated [6].
Patients who are immune due to past exposure exhibit negative HBsAg but positive anti-HBc and anti-HBs while those who have received vaccination for hepatitis B demonstrate negative HBsAg and anti-HBc with a positive anti-HBs [5].
Also, HBeAg is present when viral replication is taking place while anti-HBe is detectable when HBeAg subsides.
In addition to serology, HCV RNA testing and liver biopsy also helpful for diagnosis of hepatitis C. A reactive HCV antibody test does not determine whether the infection is acute or chronic [7] [8], hence further evaluation with HCV RNA testing is warranted. If the latter is detected, then the infection is currently active [9] [10]. Moreover, liver enzymes should be obtained.
This disease is diagnosed with the detection of IgM anti-HDV and IgG anti-HDV.
HEV infection is diagnosed by IgM anti-HEV and IgG anti-HEV. Moreover, blood and stool samples may be positive for HEV RNA.

The three major viruses that affect the liver, hepatitis A, B, and C (HAV, HBV, HCV) differ according to mode of transmission, pathology, and prognosis. [healthcommunities.com]
The prognosis for hepatitis A patients is excellent with self-limiting course, and recovery is complete. About 85 percent of people with hepatitis A recover within three months, and almost all recover within six months. [hopkinsmedicine.org]
Liver biopsy may help predict prognosis in acute hepatitis but is rarely done solely for this purpose. Complete histologic recovery occurs unless extensive necrosis bridges entire acini (bridging necrosis). [msdmanuals.com]
