托儿所内乙型肝炎的传播机理尚不清楚。由于它不是一种肠道传染病,所以不可能酿成暴发,但是,在家庭里或智残人收容机构内乙型肝炎病毒(HBV)可由人向人传播,因此,托儿所也存在HBV传播的危险性。目前,有关托儿所内HBV传播的研究资料尚少,有人观察到1名21个月的乙型肝炎e抗原(HBeAg)阳性的HBV携带者所在班级内,在17个月内检出15名托儿和6名工作人员受感染,但不能证实其中的传染关系。HBV是由皮肤或粘膜接触乙型肝炎表面抗原
The mechanism of transmission of hepatitis B in nurseries is unclear. Since it is not an intestinal infectious disease, it is unlikely that it will lead to an outbreak. However, hepatitis B virus (HBV) can be transmitted from person to person in the home or in institutions hosting the mentally retarded.

It was observed that within a period of 17 months 15 nurses were detected within a class of 21-month-old hepatitis B e antigen (HBeAg) -positive HBV carriers And six staff members were infected but could not confirm the contagion among them. HBV is exposed to hepatitis B surface antigen by the skin or mucous membranes
