It is possible to transmit H. pylori infection to family members, mainly through oral-oral and fecal-oral transmission. 1. Oral-oral transmission: If you eat together with a person infected with H. pylori, or share utensils, it is possible to transmit the infection to your family. Close contact with a person infected with H. pylori, such as kissing, may also spread to family members. 2. Fecal-oral transmission: If you don’t pay attention to hygiene, don’t wash your hands after defecation, share toiletries and toilets with others, you may be infected. Therefore, after being infected with H. pylori, it is important to pay attention to personal hygiene, do not share meals with family members, and use personal tableware and daily necessities such as toothbrushes and towels separately. Infected with H. pylori, it is recommended to consult a doctor in time and use medication under the guidance of a physician to eradicate the disease.
