Generally 100°C for 30 minutes can kill the vast majority of H. pylori, and a small number of heat-resistant strains may require 120°C to be killed. H. pylori is mainly transmitted through the digestive tract. Eating together with H. pylori-positive people, kissing and the presence of poor feeding habits, such as parents feeding by chewing food afterwards, may lead to the transmission of H. pylori. Therefore, when there are H. pylori patients in the family, they should temporarily adopt meal sharing until they are completely cured to avoid aggregated infection, and also disinfect and isolate dishes well, boiling water for at least 30 minutes to effectively kill H. pylori and reduce the chance of infection. Patients infected with H. pylori are often considered to be associated with chronic gastritis, peptic ulcer, gastric cancer and other digestive tract diseases, and it is recommended that patients promptly visit the gastroenterology department and actively cooperate with the doctor for treatment.
