大家都知道咱是乙肝大国，为什么国内的乙肝能那么猖狂，大概除了sex protection的方式不利于防病（因为乙肝的传播感染方式，美国把乙肝列入性传播疾病之一），还和饮食业的服务管理以及中国传统的和餐方式有关。建议常回国腐败的童鞋打乙肝疫苗。

有关乙肝传染，请大家看下面：

Hepatitis B 乙肝：
Hepatitis B (also called serum hepatitis) is caused by the hepatitis B virus (HBV). HBV can cause a wide spectrum of symptoms ranging from general malaise to chronic liver disease that can lead to liver cancer.

HBV spreads through:

*infected body fluids, such as blood, saliva, semen, vaginal fluids, tears, and urine
*a contaminated blood transfusion (uncommon in the United States)
*shared contaminated needles or syringes for injecting drugs
*sexual activity with an HBV-infected person
*transmission from HBV-infected mothers to their newborn babies
