Brushing dishes together for H. pylori patients is problematic and may lead to the spread of the disease. Helicobacter pylori is contagious and can be transmitted through fecal-oral and oral-oral transmission. Tableware used by patients is also a common source of infection, so if tableware used by healthy people is brushed together with tableware of Helicobacter pylori patients, it may be contagious to others. For the sake of your family’s health, you should brush the dishes of H. pylori patients separately and sterilize them at high temperatures. It is recommended that communal chopsticks be used for everyday meals, as this may also lead to the spread of the disease. H. pylori can cause chronic gastritis, gastric ulcers and even stomach cancer. If you experience adverse symptoms such as belching and epigastric discomfort, you should actively seek medical attention.
