In general, H. pylori is easily infected, and the infection rate of H. pylori in China is around 50%. H. pylori is mainly transmitted through the digestive tract, and the main ways of infection are fecal-oral transmission and oral-oral transmission. 1. Fecal-oral transmission: refers to the risk of infection after contact with fecal-contaminated food or water from an infected person. 2. Oral-oral transmission refers to the infection of food or tableware contaminated with saliva containing H. pylori from an infected person in daily life, which may infect people who eat together, or the infection of children who are infected with H. pylori when their saliva enters their mouths during kissing by an adult with H. pylori. Although Helicobacter pylori is easily infected, you can reduce the chance of infection by paying attention to protection in your daily life. For example, washing fruits and vegetables thoroughly, sharing meals in a group, separating dishes if there is a H. pylori patient in the family, sterilizing dishes, and not feeding children mouth-to-mouth. For H. pylori infection, it is recommended to sterilize and treat the infection under a doctor’s supervision.
