Boiling water does not usually kill H. pylori completely, due to factors such as short boiling time and incomplete scope of boiling, etc. The result is affected. Helicobacter pylori is a gram-negative bacterium, micro aerobic, often parasitic on the surface of the gastric mucosa, can be transmitted through the fecal-oral pathway, oral-oral pathway, causing gastroduodenal ulcers, chronic gastritis, bacterial dysbiosis and other diseases, appearing in the epigastric pain, acid reflux, nausea, abdominal distension and other symptoms. Prevention of H. pylori can be achieved through regular disinfection of tableware, such as high temperature (around 125°C) disinfection in sterilizers; washing hands before and after meals; and using communal chopsticks; however, if one uses boiling water to scald tableware on one’s own, the disinfecting effect cannot be guaranteed, and there are mainly problems with shorter scalding time and incomplete scalding range. For those who are infected with H. pylori, it is recommended that they go to the hospital, and the doctor will give them advice on treatment and prevention according to their condition. If you are worried about H. pylori infection you should try to avoid eating out or sharing meals with others as a means of prevention.
