Killing H. pylori with boiling water is suitable for disinfecting dishes, usually boiling water for 30 minutes is sufficient. H. pylori is mainly transmitted through the digestive tract. Eating together with H. pylori-positive patients, intimate contact (such as kissing, etc.) and having bad feeding habits can lead to H. pylori transmission. Therefore, if you have a patient with H. pylori at home, you should temporarily adopt a meal portioning system until you are completely cured to avoid aggregation of infection, and the dishes used by the patient should be boiled for at least 30 minutes for effective disinfection. It is also important to maintain good oral hygiene, not to eat raw food and drink raw water, and to develop good habits. In conclusion, patients with H. pylori infection need to be seen by a gastroenterologist in a timely manner and then treated with a combination of four therapies, i.e., one PPI (proton pump inhibitor), two antibiotics and one bismuth agent, as prescribed by the doctor.
