In conjunction with World Hepatitis Day on 28 July, Dr Chong spoke generally on the various types of hepatitis viruses (types A, B, C, D, E), before focusing on Hepatitis B. He said Hepatitis B virus can be transmitted from one person to another via blood or other body fluids. To limit the spread of the Hepatitis B virus, one should take preventive measures such as taking the full course of vaccinations and going for regular check-ups to check for immunity. To avoid spreading of Hepatitis B virus, one should also avoid sharing personal items such as toothbrushes and razors, covering open wounds and to ensure that sterile needles are used where necessary. Symptoms of Hepatitis B virus include pain in the joints, severe lethargy, tea-coloured urine and upper abdominal pain. In some chronic cases, complications can lead to liver cirrhosis, liver failure and early death. Dr Chong also mentioned that it is important to eat in moderation and at regular timings, to refrain from excessive or binge drinking of alcohol and to engage in regular exercise.
