EV Hepatitis B is a DNA virus with a very compact structure. It consists of a nucleus that contains DNA replication enzymes (DNA polymerase). A surface proteins of the virus that surrounds the nucleus. Humans are the only source of infection.
Infection with hepatitis B affects 300 million people and is one of the most common cause of chronic liver disease and hepatocellular carcinoma worldwide.
Hepatitis B often produces no symptoms. Sometimes, the chronically infected by the virus have no symptoms. Chronic liver damage can occur in people who are chronically infected, after decades of early infection.
The increased risk of progression of chronic liver disease in infants born to infected mothers. This transmission is the most common way of spreading hepatitis B.
Hepatitis B, the presence of hepatitis B carriers are not active liver histology and normal function suggests that this virus is not directly cytopathic. Patients who have low cellular immunity is more likely to remain chronically infected and to clean the virus of hepatitis B.
Symptoms and signs
Acute viral hepatitis occurs after an incubation period of 30 to 180 days are varied. Symptoms of acute viral hepatitis is variable. Patients may have symptoms such as anorexia, nausea and vomiting, fatigue, joint pain, muscle aches, headache, sore throat, cough and cold medicines that can be followed by the development of yellowing (jaundice). Fever hepatitis B is usually low grade or absent. Dark urine and feces may go unnoticed by patients 1-5 days before the onset of yellowing (jaundice).
When symptoms are jaundice gradually subsided. There are upper abdominal pain or discomfort. The spleen may be enlarged in some patients with enlarged lymph nodes. This if followed by a recovery of about 3-4 months.
