Abstract:

Helicobacter pylori（Hp） is responsible for one of frequent chronic bacterial infections worldwide and most likely spread from person to person through fecal-oral or oral-oral routes. Children are at high risk of Hp infection. Hp infection in childhood is clustered in the family members，and associated closely with social economic status，personal hygiene and the feeding way. To promote health education，advocate breastfeeding，improve basic sanitation and family health behavior，pay attention to hand hygiene and correct poor diet living habits would be critical to reducing the incidence rates of Hp infection in childhood.

Key words: Helicobacter pylori, route of transmission, risk factors, prevention, child

摘要：

幽门螺杆菌（Hp）感染是世界范围最为常见的慢性感染性疾病之一，Hp感染可通过口-口途径和粪-口途径传播。儿童是Hp感染的高危时期，儿童Hp感染呈现家庭内聚集，且与社会经济状况、个人卫生习惯及喂养方式密切相关。开展健康教育，提倡母乳喂养，改进基础卫生设施和家庭卫生行为，注意手卫生及纠正不良饮食生活习惯等将会对降低儿童Hp感染率起重要作用。
