目前,人们对于幽门螺旋菌的感染与传播了解得很少。流行病学证据支持该病菌在密集的社区和家庭中人-人传播的观点。对志愿者研究证实,该菌可经消化道传播,提示食物或水是潜在的传染源。某些研究也发现,接触动物或肉类的职业与该菌的感染定位似乎有关,但到目前为止,极少从家畜,尤其 At present, little is known about the infection and transmission of Helicobacter pylori.

Research on volunteers confirmed that the bacteria can be transmitted through the digestive tract, suggesting that food or water is a potential source of infection. Some studies have also found that occupational exposure to animals or meat appears to be related to the infection orientation of the bacteria, but so far, very rarely from domestic animals, especially
