cause of helicobacter pylori infection

Generally speaking, some of the causes of infection, or some ways of infection, are mouth-to-mouth transmission. What does mouth-to-mouth transmission refer to? For example, when grandma takes care of her grandson, when feeding her grandson, sometimes she blows at the food with her mouth, or cools it in her mouth and then feeds it to the child. It is mouth-to-mouth transmission. We share chopsticks, bowls, even teacups and cups when eating in a family, gargle with the same cup when gargling, etc. These ways are all ways of causing Helicobacter pylori infection or transmission. Fecal-oral transmission, such as vegetables, some of our vegetables are watered by our human feces or organic fertilizer, vegetables are not washed clean, and then to our import, this means faecal-oral transmission. Stomach-mouth transmission of infection, that is, when our gastroscope disinfection is not strict, a person after gastroscope disinfection is not strict, and then do another patient, may also spread this Helicobacter pylori, we know that the digestive tract is the only way of transmission, eating together is the main reason.
