Helicobacter pylori is not hereditary. Helicobacter pylori is a bacterium that parasitizes the sinus of the stomach and often leads to peptic ulcers and chronic gastritis, and this bacterium can spread among people. The infection rate of H. pylori in the Chinese population is as high as 50%, and as high as 80% in some places. In areas where H. pylori is widely distributed, the incidence of gastric cancer also increases, so it is very necessary to eradicate H. pylori. Helicobacter pylori spreads through fecal-oral route in the population, that is to say, after we eat this bacterium, this bacterium resides in the gastric sinus to form the onset of the disease, so when someone in the family is infected with Helicobacter pylori, the rate of infection of our family members will also increase. But it’s not hereditary, it’s a mutual infection.
