Patients infected with H. pylori should keep their dishes separate from those of other people. The main reason for this is that H. pylori can be transmitted orally and fecally, so it is important to separate the dishes of patients infected with H. pylori from those of people who are not infected. In addition, oral hygiene products should also be separated. To prevent H. pylori infections in groups, dishes should be disinfected regularly, and scratched dishes should be replaced regularly. Weak children and the elderly should also try to use high-risk sterilized stainless steel tableware to avoid disease from the mouth.
