世界上超过一半的人口受到感染。

幽门螺杆菌感染的流行率在全球范围内因社会经济因素和卫生水平而异。 研究人员对 1970 年至 2016 年的 184 项研究进行了荟萃分析，以检查 62 个不同国家不同时期的幽门螺杆菌患病率。

结果如下：

世界上超过一半的人口受到感染。

尽管美国和澳大利亚的幽门螺杆菌患病率较低（分别为 35.6% 和 24.6%），但它们的原住民人口患病率很高（阿拉斯加原住民为 74.8%，西澳大利亚原住民为 76.0%）。

患病率最高的地区是非洲（70.1%）、南美洲（69.4%）和西亚（66.6%）； 患病率最低的地区是大洋洲 (24.4%)、西欧 (34.3%) 和北美 (37.1%)。

患病率最高的国家是尼日利亚（87.7%）、葡萄牙（86.4%）和爱沙尼亚（82.5%）； 患病率最低的国家是瑞士 (18.9%)、丹麦 (22.1%) 和新西兰 (24.0%)。

比较 1970-1999 年和 2000-2016 年期间，幽门螺杆菌患病率在欧洲（48.8% 至 39.8%）和北美（42.4% 至 26.6%）有所下降，但在西亚（53.6% 至 54.3%）保持不变 和拉丁美洲/加勒比地区（62.8% 至 60.2%）。

据估计，2015 年全球幽门螺杆菌感染人数为 44 亿人。

Global Prevalence of Helicobacter pylori

More than half of the world's population is infected.

The prevalence of Helicobacter pylori infection varies globally according to socioeconomic factors and levels of hygiene. Investigators performed a meta-analysis of 184 studies from 1970 to 2016 to examine H. pylori prevalence in 62 different countries at different times.

Results were as follows:

More than half of the world's population is infected.

Whereas the U.S. and Australia have a low prevalence of H. pylori (35.6% and 24.6%, respectively) their indigenous populations have a high prevalence (74.8% in indigenous Alaskans and 76.0% in Western Australia indigenous populations).

The regions with the highest prevalence were Africa (70.1%), South America (69.4%), and Western Asia (66.6%); regions with the lowest prevalence were Oceana (24.4%), Western Europe (34.3%), and North America (37.1%).

Countries with the highest prevalence were Nigeria (87.7%), Portugal (86.4%), and Estonia (82.5%); countries with the lowest prevalence were Switzerland (18.9%), Denmark (22.1%), and New Zealand (24.0%).

Comparing the periods of 1970–1999 and 2000–2016, H. pylori prevalence decreased in Europe (48.8% to 39.8%) and North America (42.4% to 26.6%), but remained unchanged in Western Asia (53.6% to 54.3%) and Latin America/Caribbean (62.8% to 60.2%).

The global prevalence of H. pylori in 2015 was estimated to be 4.4 billion people.
