About 30 percent of people with hepatitis B experience no symptoms, and symptoms are even less common in children. If symptoms do appear, they usually occur 4 to 6 weeks after the time of infection and can range from mild to severe.
The following symptoms may develop with hepatitis B infection:
Fatigue, weakness, joint aches, and low-grade fever.
Nausea, vomiting, loss of appetite, and abdominal pain, especially around the liver.
Yellowing of the skin and eyes (jaundice) and dark urine.
Hepatitis B can damage your liver and spread to other people, even if you don't have any symptoms. Anyone who has a risk factor for hepatitis B infection should be tested by a health care provider.
