Will parents be infected with Helicobacter pylori and pass it on to their children?

H. pylori infection does not necessarily spread to children from parents.

The main transmission routes of H. pylori are mouth-to-mouth transmission and faecal-to-mouth transmission. Infected people excrete H. pylori through saliva, vomit, feces, etc. Others may be infected with H. pylori after exposure to infected substances. In a family, if one member is infected with H. pylori, other family members may also be infected, such as sharing dishes, towels, and using the same bathroom can increase the risk of infection. It is important to note that not every infected person causes others to become infected with H. pylori. In addition, the spread of H. pylori can be affected by treatment and prevention measures.
