Hepatitis B




Hepatitis means inflammation of the liver. Hepatitis B (also called serum Hepatitis) is caused by the Hepatitis B virus (HBV). HBV can cause a spectrum of symptoms ranging from general malaise to chronic liver disease that can lead to cancer of the liver.

Signs and Symptoms

Most children and many adults don’t have symptoms.

Symptoms, if present are similar to Hepatitis A

  • Yellow skin or eyes (jaundice)
  • Feeling very tired
  • Abdominal pain
  • Loss of appetite
  • Nausea
  • Diarrhea
Incubation Period

The incubation period is between two weeks to six months, but usually six to nine weeks.

Mode of Transmission

Contact with infected person’s blood/body fluids

Sharing injection drug or tattooing equipment

Unprotected sex

Infected mother to her infant during delivery or breastfeeding

Household contact

Occupational exposure through needle stick

Period of Communicability

With Hepatitis B, 85% to 90% of patients recover from their illness completely within 6 months, without long-term complications. People with Hepatitis B who continue to be infected can develop chronic Hepatitis and cirrhosis of the liver. Some people may also become lifelong carriers of the virus and can spread the disease to other people.
