乙型肝炎病毒传播途径通常是经皮穿刺，约占医源性感染的3／4。在我国一些农村地区，2～4岁儿童HBV感染率较高，可能与预防接种时注射器消毒不严、共用针头或针筒有关。美国、英国均有与针刺有关的乙型肝炎暴发流行。因此，接种时“一人一针一管一消毒”是避免交叉感染的重要措
Hepatitis B virus transmission is usually percutaneous puncture, accounting for about three-fourths of iatrogenic infections. In some rural areas of our country, 2 to 4 years old children have a higher HBV infection rate, which may be related to the lack of syringes disinfection when vaccinated with vaccines and shared needles or syringes. Both the United States and Britain have acupuncture-related hepatitis B outbreaks. Therefore, inoculation “one person one needle one tube one disinfection” is an important measure to avoid cross-infection
