本文综述了2007年4月至2008年3月间发表在同行评议期刊上的幽门螺杆菌流行病学研究。螺杆菌感染幽门螺杆菌通常发生在儿童时期，一旦建立，如果不治疗，可以持续终生。H.与发达国家相比，发展中国家的幽门螺杆菌感染率更高，并且可能因种族、出生地和社会经济因素而异，甚至在生活在同一国家的人之间也是如此。在许多国家，由于卫生和生活水平的改善以及最近人口从农村向城市的流动，感染率正在下降;然而，H.在发展中国家和发达国家的特定人群中，幽门螺杆菌感染率仍然很高。此外，最近的一些研究已经开始探讨儿童感染H。幽门螺杆菌和预防哮喘和过敏。
This review summarizes studies on the epidemiology of Helicobacter pylori published in peer-reviewed journals between April 2007 and March 2008. Infection with H. pylori often occurs in childhood, and once established, can persist lifelong if untreated. Prevalence of H. pylori infection is higher in developing countries when compared to developed countries, and can vary by ethnicity, place of birth, and socioeconomic factors even among persons living in the same country. Prevalence of infection is decreasing in many countries due to improvements in sanitation and living standards and the relatively recent movement of populations from rural to urban settings; however, post-treatment recurrence rates of H. pylori infection remain high in developing countries, and in given populations within developed countries. In addition, a number of recent studies have begun to explore the possible link between childhood infection with H. pylori and protection against asthma and allergy.
