If one spouse is infected with H. pylori, the other spouse may not necessarily be infected as well, although the probability of infection is relatively higher. The main ways of transmission of H. pylori are oral-oral and fecal-oral, such as kissing, mouth-to-mouth feeding, or sharing utensils, as well as coming into contact with food and water contaminated by the patient’s feces and vomit, all of which may be contagious. After either spouse is infected with H. pylori, the probability of the other being infected is also higher. However, it is not a sure thing that you will get infected. After the diagnosis of H. pylori infection, if you strengthen the isolation protection in time, avoid sharing tableware, good hygiene, avoid kissing and other close contact, you can effectively avoid transmission. This disease is highly contagious, once diagnosed, should seek medical treatment as soon as possible. Only by curing the disease can we better prevent infection.
