HEPATITIS B

Dr. P. Siva Bharathi, M.D (Peds), AB (USA).

1. What is hepatitis B?

Hepatitis B is a serious disease that affects the liver. It is caused by the hepatitis B virus (HBV). HBV can cause:

Acute (short-term) illness. This can lead to:

  • loss of appetite
  • diarrhea and vomiting
  • tiredness
  • jaundice (yellow skin or eyes)
  • pain in muscles, joints, and stomach

Acute illness is more common among adults. Children who become infected usually do not have acute illness.

Chronic (long-term) infection. Some people go on to develop chronic HBV infection. This can be very serious, and often leads to:

  • liver damage (cirrhosis)
  • liver cancer
  • death

Chronic infection is more common among infants and children than among adults. People who are infected can spread HBV to others, even if they don’t appear sick.

Hepatitis B virus is spread through contact with the blood or other body fluids of an infected person. A person can become infected by:

  • contact with a mother’s blood and body fluids at the time of birth
  • contact with blood and body fluids through breaks in the skin such as bites, cuts, or sores; – contact with objects that could have blood or body fluids on them such as toothbrushes or razors
  • having unprotected sex with an infected person
  • sharing needles when injecting drugs
  • being stuck with a used needle on the job.
