乙型肝炎慢性携带者,是 Hoofnagle 1974年在美国第六次红十字会科学讨论会上提出来作为一种重要类型并将其特征化,是指那些没有典型发病史而体内携带 HBsAg 持续六个月以上而外表健康的人。国内一般习惯称为“健康携带者”,但由于它具有迁延或持续倾向,故国外多称为慢性携带者。它是乙肝病毒在人群中存在的主要形式,为数众多,具有比病人更为重要的流行病学意义。
Chronic carriers of hepatitis B, which Hoofnagle presented as a significant type at the Sixth Red Cross Scientific Symposium of the United States in 1974, are characterized by the absence of a history of typical onset while carrying HBsAg in vivo for six Months and above the appearance of healthy people. Domestic habits are commonly referred to as “health carriers”, but because of its persistence or persistence, it is often referred to as a chronic carrier abroad. It is the major form of hepatitis B virus present in the population, numerous and of more epidemiological significance than the patient.
