一、病毒性肝炎是怎样传播的?病毒性肝炎有甲型肝炎(甲肝HA)、乙型肝炎(乙肝HB)和非甲非乙型肝炎(HNANB)三种,其传染源及传播途径介绍如下:(一)甲型肝炎:目前研究表明,HA 病人没有慢性排毒现象,在健康人群中也不存在HAV 携带者,其唯一传染源是现症患者,尤其是早期患者。病人感染HAV 后的潜伏期15～50天,平均30天左右。在潜伏期后期至黄疽前期开始从粪便中排毒,排毒高峰是感染后的第17～19天或黄疸前6～7天。部分病人出现黄疸后已停止排毒,有的虽继续排毒,但时间不长,感染力不强。排毒时间最长的可至起病后第18天。
First, what is the spread of viral hepatitis? Hepatitis A (Hepatitis A), Hepatitis B (Hepatitis B) and Non-Hepatitis B (HNANB), the source of infection and transmission are described below (A) Hepatitis A: The current study shows that there is no chronic detoxification in patients with HA, HAV carriers do not exist in healthy people, the only source of infection is in patients with disease, especially in early patients. Patients infected with HAV incubation period of 15 to 50 days, an average of 30 days. In late incubation period to jaundice began detoxification from the stool, detoxification peak is 17 to 19 days after infection or jaundice 6 to 7 days. Some patients have stopped detoxification after jaundice, although some continue detoxification, but not long, the infection is not strong. The longest detoxification time to eighteen days after onset.
