日本健康人中虽HB_sAg阳性率仅有2—3%,但HB_sAb的阳性率则高达20—30%,证明HBV的传播很广,乙型肝炎的传播一般认为由输血、医疗事故、母亲与小儿之间及家族内感染引起,但大多病例的传播方式尚不了解,以蚊虫为媒介,经皮肤感染的可能性不能排除,故作者从11例HB_sAg持续阳性的慢性肝炎患者家庭中捕集蚊虫进行研究。将每一例家庭所捕捉的蚊子混合在一起进行检查,结果其中2例从蚊中可检出HB_sAg,而HB_sAb全部阴性,在2例中的一例的蚊虫HB_eAg阳性。同时对29例非输
Although the positive rate of HB_sAg in Japanese healthy people is only 2-3%, the positive rate of HB_sAb is as high as 20-30%, which proves that the spread of HBV is very broad. The spread of hepatitis B is generally considered to be caused by blood transfusion, medical accidents, mothers and children And within the family caused by infection, but most of the cases of transmission is not yet understood, mosquito-mediated, the possibility of skin infections can not be ruled out, so the authors from 11 cases of persistent HB_sAg-positive chronic hepatitis patients in families trapped mosquito the study. The mosquitoes captured by each family were mixed and examined. As a result, HBsAg was detected in 2 of the mosquitoes, but negative in all of the HBsAbs. In one of 2 cases, the mosquitoes were positive for HB_eAg. At the same time on the 29 non-lose
