People with H. pylori do not need to wash their clothes separately. H. pylori is not transmitted through clothing, but through fecal-oral and oral-oral transmission. 1. Fecal-oral transmission: The feces of H. pylori patients contain large amounts of H. pylori. If the food is infected by the feces containing H. pylori, other people will be infected with H. pylori after eating it. Therefore, it is important to wash your hands frequently, especially before and after meals, and to wash fruits and vegetables and other foods. 2. Mouth-to-mouth transmission: the saliva of H. pylori infected people contains a lot of H. pylori. Behaviors such as intimate kissing, mouth-to-mouth feeding, and not using chopsticks to hold food are prone to H. pylori infection. Therefore, if you live with a person with H. pylori, you should avoid these high-risk behaviors, practice meal sharing, and use dishes after they have been sterilized at high temperatures. If you are diagnosed with H. pylori, it is recommended that you undergo standardized treatment as soon as possible to minimize the adverse effects of the disease.
