自1983年澳大利亚学者报告了从人胃粘膜分离到幽门螺杆菌(Helicobacter pylori,Hp)以来,由于其在人群中有较高的感染率,且与多种消化道疾病有关,而引起了国内外许多学者的重视。本文就Hp感染的人群分布概况、传播途径及影响因素、防治等研究进展作一综述。 1 人群中Hp感染概况 对Hp感染的流行病学调查资料表明,Hp感染在儿童期即已达较高水平,血清抗Hp-IgG总阳性率为45.15％,<1岁抗Hp-IgG阳性率就已达 Since 1983, when Australian scholars reported that Helicobacter pylori (Hp) was isolated from human gastric mucosa, it has caused widespread infection in the population and has been associated with many gastrointestinal diseases, Many scholars attach importance. In this paper, the population distribution of Hp infection, transmission routes and influencing factors, prevention and treatment are reviewed. Hp infection in a population Hp infection epidemiological survey data show that Hp infection reached a high level in childhood, serum anti-Hp-IgG total positive rate was 45.15%, <1-year-old anti-Hp-IgG positive rate It has been reached
