Helicobacter pylori can survive for about half an hour on tableware. Because the growth conditions of H. pylori culture in vitro are very harsh and it is a microaerobic bacterium itself, it is usually difficult for H. pylori to survive for more than two hours in vitro, and it can usually survive for about half an hour on tableware. Helicobacter pylori is mainly transmitted through oral and fecal-oral transmission. If you use dishes that have been used by a patient, the bacteria can be transmitted to family members or close contacts through the saliva left on the dishes. After H. pylori is excreted in the stool, the feces can contaminate water sources, which can lead to fecal-oral transmission if the water is consumed or if the person touches food without washing his/her hands with H. pylori residues. In addition, if you are infected with H. pylori, it is recommended that you go to the hospital in a timely manner and follow the doctor’s instructions for treatment. Don’t worry too much about the risk of passing H. pylori to each other, as long as you pay attention to personal hygiene, you can usually avoid passing it to each other.
