Hepatitis B

What is Hepatitis B?

Hepatitis B is a liver disorder caused by the hepatitis B virus (HBV). It is an infection that may eventually lead to liver failure, liver cancer or cirrhosis. The disease can be prevented using a vaccine which also prevents the infection from spreading. 


Symptoms of hepatitis B, whether it be mild or severe, mostly appear after four months of getting infected:

  • Fever
  • Pain in the abdomen
  • Loss of appetite
  • Pain in the joints
  • Dark urine
  • Weakness and fatigue
  • Vomiting and nausea
  • Yellowing of your skin and the whites of your eyes


Hepatitis B virus(HBV) causes hepatitis B infection. This virus gets passed on from one person to other through semen, blood or body fluids. Some ways by which HBV gets passed on are:

  • Sharing needles and syringes with a person whose blood was infected with HBV.
  • Sexual contact with a person who has hepatitis B.
  • Mother to child during pregnancy.


Some of the factors that increase the chances of getting infected from hepatitis B are:

  • Working at a place that exposes you to human blood.
  • Living with a person who is diagnosed with hepatitis B.
  • Unprotected sexual intercourse with someone who is infected with HBV.
  • Traveling to areas that have high infection rates of hepatitis B, for example Central and Southeast Asia, Eastern Europe and Africa.
  • Sharing needles with others while injecting drugs.


The disease can be prevented by the following means:

  • Get vaccinated before travelling
  • Use protection when ever you have sex
  • Take precautionary steps while tattooing and body piercing
  • Find out the HBV status of your sexual partner
  • Stop using illicit drugs
