Hepatitis B is one of the common viral Hepatitis in Hong Kong. Referring to the data provided by Department of Health, HK, overall prevalence of chronic Hepatitis B infection in Hong Kong is high (>8%).
HBV can be transmitted through blood contact, sexual contact and mother to child transmission at or around the time of delivery.
- Mild fever
- Abnormal pain
- Jaundice (yellowing of skin and eyes)
- Nausea and vomiting
- Dark urine
However, the majority of patients do not have any symptom at all.
5-10% of infected adult and 70-90% of infected infants are unable to clear the virus, thus becoming chronic carriers and serving as sources of infection to others.
About 25% of the carriers would develop chronic liver damage including cirrhosis and liver cancer.
- The most effective method is through Hepatitis B vaccination, which takes a total of three injections in the complete course of vaccination.
After a full course of vaccination about 90 to 95% of people will gain life-long immunity to Hepatitis B.
It is preferable to have blood test before vaccinated as only people who have never been exposed to Hepatitis B should be vaccinated.
Since 1988, babies born in Hong Kong have received Hepatitis vaccination.
- Handle open wounds carefully and wear gloves when you expect to be in contact with bloods of others;
- Do not share razors and toothbrushes or needles with other people.
- Be careful if you decide to undergo procedures like tattooing and acupuncture. Make sure clean and disposable instruments are used.
- Limit the number of your sexual partners. Practice safer sex and use the condom properly.
Antiviral drugs are able to suppress HBV replication and thereby reduce virus-induced liver damage of chronic Hepatitis B infection. Consult your doctors for the appropriateness of these drugs.
Regular body check including blood test for liver function and alpha-fetoprotein and ultrasonography liver examination to detect changes in the liver whereby early treatment could be possible.
