Overview

History

Acute HBV infection is frequently asymptomatic. The presence of symptoms depend on age and immunocompetence. History taking The symptoms of HBV HBV infection may present with symptoms is often asymptomatic, but

Symptoms

Approximately, 50% of adults with acute HBV infections are asymptomatic. However, clinical symptoms occur more often in adults than in infants or children, who usually have an asymptomatic acute course.^[1]

Symptoms can include:

Fever
Fatigue
Nausea
Vomiting
Loss of appetite
Abdominal pain
Dark urine
Clay-colored bowel movements
Joint pain
Yellowish discoloration of the eyes and skin

-Hepatitis B virus infection may either be acute (self-limited) or chronic (long-standing). Persons with self-limited infection clear the infection spontaneously within weeks to months.
-===Children===
-Children are less likely than adults to clear the infection. More than 95% of people who become infected as adults or older children will stage a full recovery and develop protective immunity to the virus. However, only 5% of newborns that acquire the infection from their mother at birth will clear the infection. Of those infected between the age of one to six, 70% will clear the infection. When the infection is not cleared, one becomes a chronic carrier of the virus.
-===Acute Infection===
-Acute infection with hepatitis B virus is associated with acute viral [[hepatitis]] - an illness that begins with general ill-health, loss of appetite, nausea, vomiting, body aches, mild fever, dark urine, and then progresses to development of [[jaundice]]. It has also been noted that itchy skin all over the body has been an indication as a possible symptom of all hepatitis virus types.  The illness lasts for a few weeks and then gradually improves in most affected people. A few patients may have more severe liver disease ([[fulminant hepatic failure]]), and may die as a result of it. The infection may also be entirely asymptomatic and may go unrecognized.
-===Chronic Infection===
-Chronic infection with hepatitis B virus may be either asymptomatic or may be associated with a chronic inflammation of the liver (chronic hepatitis), leading to [[cirrhosis]] over a period of several years. This type of infection dramatically increases the incidence of [[liver cancer]].
-===Co-infection with Hepatitis D===
-[[Hepatitis D]] infection usually only occurs with a concomitant infection with hepatitis B.<ref>Lok A.  [http://www.patients.uptodate.com/topic.asp?file=livertrn/2133 Hepatitis D virus infection and liver transplantation.] uptodate.com. Retrieved on September 11, 2007.</ref> Co-infection with hepatitis D increases the risk of liver cirrhosis and subsequently, liver cancer.
-[[Polyarteritis nodosa]] is more common in people with hepatitis B infection.
