I was in the clinical clinic, when I found a patient was found to be infected with Helicobacter pylori, asked the family history has a lot of similar diseases, a family sometimes the whole family suffers from gastric disease, according to them all have seen a doctor, that is, the treatment is not effective, when it comes to gastric disease can also be contagious, most people do not have this concept, therefore, today I put the gastric disease can also be contagious reasons to analyze for your reference. ”Gastric disease”, it includes acute gastritis, chronic gastritis and gastric, duodenal bulb ulcer and other diseases, the description of gastric disease can not be found in the medical literature, “gastric disease” is the common people talk about it. Today’s “gastric diseases can be contagious” does not mean that all “gastric diseases” are contagious, and those that are contagious do not belong to the often talked about “contagious diseases”. The concept of “contagious disease” is not a concept that is often referred to as “infectious disease”. The term “stomach disease is contagious” refers to “stomach disease” that is infected with H. pylori, and in many cases, it is contagious. H. pylori (HP), a bacterium present on the gastric mucosa, is the root cause of “gastric disease” transmission, and the main way of transmission is fecal-oral or oral-oral transmission. For example, drinking contaminated water, close contact between people with H. pylori and their families, contact between children in kindergartens and eating unclean food from roadside stalls can cause the spread of H. pylori, leading to the occurrence of “gastric disease”. Our country is infected with H. pylori on the population of about 50%, individual regions or departments can be as high as 80%, so the incidence of gastric disease is also very high. That is, it is the culprit of chronic gastritis and gastric and duodenal bulb ulcers and other diseases. The long-term attack of H. pylori on the stomach may also lead to the development of gastric cancer. Although the transmission route of H. pylori is similar to that of other infectious diseases of the digestive tract, H. pylori infection is less invasive and pathogenic, and it takes a longer time or a large number of bacteria to attack the gastric mucosa before it leads to serious diseases. Therefore, preventing H. pylori infection and cutting off the transmission route of H. pylori is an important part of preventing the occurrence of gastric disease. H. pylori can be found in feces, saliva, dental tartar, and vomit, so it is important to emphasize cleanliness and hygiene and to wash your hands before and after meals, especially before eating, so that you can prevent the spread of H. pylori and the occurrence of other infectious diseases. Patients who have been detected with H. pylori should avoid contact with others and take the necessary formal anti-H. pylori treatment. At present, most of the clinics take triple and quadruple therapy: the removal rate of Helicobacter can reach 85-90%. In order to prevent the transmission of “stomach disease”, it is best to implement a system of sharing food in the family, adults do not feed children mouth to mouth, to keep the oral hygiene, brush teeth regularly.
