The route of transmission of H. pylori is still not fully understood, but most studies have concluded that most patients are transmitted through the person-to-person fecal-oral, oral-oral, and gastro-oral routes. Among these, the notion that the infection is aggregated in families due to the common Chinese system of sharing meals is supported by most medical and scientific researchers. In other words, if one person has H. pylori infection at a dinner party and his chopsticks are used to pick up a dish on the plate, you may be infected with H. pylori if you pick it up again. As we are now in the second child boom, many elderly people like to eat it themselves and taste it before giving it to their children, so there are cases of children infected with H. pylori. So, what should children with H. pylori infection, Bandy do? First of all, whether children need to be tested for H. pylori, according to China’s Expert Consensus on the diagnosis and treatment of H. pylori infection in children, H. pylori testing is not recommended routinely for children. That is, for children, testing and treatment strategies do not apply unless there is a specific disease treatment need to test children for H. pylori, and children should not be tested simply for H. pylori infection. This means that if your child if nothing in particular, you should not seek medical attention to get tested because a parent has H. pylori infection. Does it matter if my child has H. pylori and I don’t know about it? According to studies, most H. pylori infections in developing countries occur in childhood, mainly around the age of 5. If infected with HP, our main concern is that it can cause gastric and duodenal peptic ulcers, gastric non-cardia adenocarcinoma, and gastric mucosa-associated lymphoma in children. In children infected with H. pylori, the incidence of inflammatory reactions or ulcers in the gastric and duodenal mucosa are much lower than in adults. Currently, children do not need to seek medical attention for parental H. pylori infection or simply to find out if their child has H. pylori infection for peace of mind. The following children have indications for testing for H. pylori infection: 1. peptic ulcer; 2. lymphoma of the gastric mucosa-associated lymphoid tissue; 3. chronic gastritis; 4. a child with a first-degree relative with gastric cancer; 5. unexplained refractory iron deficiency anemia; 6. planned long-term use of nonsteroidal anti-inflammatory drugs, including low-dose aspirin.
