關於B型肝炎

B型肝炎是經由B肝病毒(HBV)傳染,B型肝炎病患可增加罹患肝硬化,肝衰竭以及肝癌的機率。全球有80%的肝癌患者得病都是因為本身罹患B型肝炎的緣故。

Most people who have chronic hepatitis B are completely unaware they have it. The first step is knowing.

B型肝炎傳染途徑

The hepatitis B virus (HBV) is transmitted through infected blood in the following ways:
 

BBS: Birth, Blood and Sex

  • Birth: From a mother to a child at the time of birth (most common for APIs)

  • Blood: Contact with infected blood (needle sharing)

  • Sex: Unprotected sex

Among the Asian & Pacific Islander (API) community, transmission of HBV frequently occurs during the birth process when the virus is passed on to the baby from a mother who is often unaware that she is infected. If symptoms do appear they often are exhibited at the end stages of disease when treatment options are limited or ineffective.

Since perinatal transmission is the most common, prevention is of the utmost importance in the Asian community.

HBV is very efficiently transmitted by unprotected sex, so all API adults who are sexually active should be vaccinated to prevent infection.

 

In addition, the younger the individual at the time of exposure, the greater the risk of developing life-long chronic hepatitis B: 

  • More than 90% of infants (1 or less) who are infected with hepatitis B will develop chronic hepatitis B.

  • 30% - 50% of young children between 1 and 5 years who are infected will develop chronic hepatitis B.

  • Only 5-10% of healthy adults 19 years and older who are infected will develop chronic hepatitis B infection (that is, 90% will get acute hepatitis B and recover).

 
 
B型肝炎傳染途徑

Most APIs are infected at birth or early childhood, when symptoms may never develop. Thus the disease can progress undetected. If symptoms do appear, they often appear too late, when the disease has become fatal and when treatment options are limited or ineffective. Only 30% of those with acute infections develop symptoms. When symptoms of hepatitis B infection do develop, they include: 


• Jaundice
• Fatigue
• Abdominal pain
• Loss of appetite

關於B型肝炎

B型肝炎是經由B肝病毒(HBV)傳染,B型肝炎病患可增加罹患肝硬化,肝衰竭以及肝癌的機率。全球有80%的肝癌患者得病都是因為本身罹患B型肝炎的緣故。

B型肝炎傳染途徑

A hepatitis B infection can result in either an acute infection or a chronic infection. When a person is first infected with the hepatitis B virus, it is called an "acute infection" (or a new infection). Most healthy adults that are infected do not have any symptoms and are able to get rid of the virus without any problems. Some adults are unable to get rid of the virus after six months and they are diagnosed as having a "chronic infection." A simple blood test can diagnose an acute or chronic hepatitis B infection.

The risk of developing a chronic hepatitis B infection is directly related to the age at which a person is first exposed to the hepatitis B virus. The younger a person is when they are first infected, the greater the risk of developing a chronic hepatitis B infection:

  • More than 90% of infants that are infected will develop a chronic hepatitis B infection

  • Up to 50% of young children between 1 and 5 years who are infected will develop a chronic hepatitis B infection

  • 5-10% of healthy adults 19 years and older who are infected will develop a chronic hepatitis B infection (that is, 90% will recover from an exposure)

 

Most pregnant women do not know whether they are infected with hepatitis B and can unknowingly pass the virus to their newborns during childbirth. Therefore, since the risk of newborns becoming chronically infected at birth is so high, both the World Health Organization and the U.S. Centers for Disease Control and Prevention recommend that all infants receive the first dose of the hepatitis B vaccine within 12-24 hours after birth.

The recommendation for hepatitis B vaccination of babies and children is so important because they are at the greatest risk of developing a chronic infection if they are not protected against the hepatitis B virus as soon as possible. 

B型肝炎傳染途徑

"Hepatitis" refers to any disease that results in inflammation of the liver, regardless of how that disease is contracted. 

A型肝炎

A 型肝炎的傳染途徑是「經口感染」也叫做「糞口感染」,也就是說當吃到或喝到遭 A 型肝炎病毒污染(病人的糞便)的食物或飲水時會感染到 A型肝炎。
A型肝炎可經由疫苗預防傳染。

 

B型肝炎

B型肝炎可分為急性與長期感染,可經由受污染的血液與性行為的分泌物水平感染。
B型肝炎可經由疫苗預防傳染。

 

 

C型肝炎

C型肝炎可分為急性與長期感染,是經由受污染的血液水平感染。
C型肝炎目前為止沒有有效的疫苗能預防傳染。
