H. pylori can be transmitted to loved ones, but proper protection can prevent transmission. Helicobacter pylori is easily transmitted from one family member to another and has a family history of clustering. Therefore, H. pylori infection can be transmitted to loved ones and family members, but proper protection can prevent the infection. H. pylori is mainly transmitted through “oral-oral transmission” and “fecal-oral transmission”, which can be transmitted through direct contact with saliva (e.g., kissing), vomit or feces of the infected person, as well as through contaminated food, drinking water, and tableware. Daily attention to personal hygiene, washing hands frequently, and not eating half-raw or undercooked food can prevent H. pylori infection. Intimate daily contact between family members (including kissing, sharing meals, sharing drinking glasses, etc.) can easily lead to intra-family transmission and should be avoided. Use communal chopsticks when sharing meals with others, do not cross-use tableware, and pay attention to the sterilization of tableware. After being infected with Helicobacter pylori, eradication should be carried out under the guidance of a medical professional to avoid delays.
