It can lead to complications like liver cirrhosis(scarring), chronic hepatitis ( liver inflammation) and even liver cancer which can eventually lead to death after many years.
Hepatitis B can be prevented with effective vaccination. In Singapore, estimated 3-4% population infected by hepatitis B virus,. more common in chinese population. Hepatitis B most commonly transmitted between mother and newborn where the transmission rate is as high as 10% from mothers with high virus count to their new born, so it is compulsory for babies born to hepatitis B positive mothers to be vaccinated and given a special injection (with hepatitis B immune globulin) after birth.
What Are The Symptoms Of Hepatitis B?
Most patient with hepatitis B does not have symptoms. In some adult with acute hepatitis B, they can have symptoms of loss of appetite, persistent fatigue, vomiting, and jaundice. You have chronic hepatitis B if you have the Hepatitis B surface antigen positive (a blood test) for more than 6 months, even if you do not show any symptoms. Most people would not know they are infected unless they get tested in a clinic. For those with chronic hepatitis B, the silent damage to the liver can occur for years until liver cirrhosis or liver cancer is discovered when it may then be too late.

They may have weight loss and abdominal pain if there is associated advanced liver cancer. Patient with advanced cirrhosis may also suffer from kidney failure, confusion or difficulty breathing.
How Is Hepatitis B Transmitted?
The virus is transmitted by exposure to infectious blood or body fluids of someone who has chronic hepatitis B. it can be passed to someone else through unprotected sex, contaminated needles or other skin-piercing objects, direct contact of the blood or open sore, and transmission at birth from infected mother to child. It is not spread by casual contact, sharing of eating utensils, coughing and sneezing, or breastfeeding.

Blood tests are carried out to diagnose Hepatitis B. If detected early, it can be controlled with medication in some cases to prevent complications of liver cirrhosis and liver cancer. Not all cases of hepatitis B need treatment.
Imaging of the liver is recommended to be done every 6 months to detect liver cancer early. Early liver cancer is treatable.
Your specialist may also carry out test to assess the extent of fibrosis of the liver, typically using a fibroscan. It is non-invasive and provides valuable information.
