Helicobacter pylori is not airborne, but is generally transmitted through the fecal-oral and oral-oral routes. 1. Fecal-oral route: It means that the feces containing H. pylori indirectly or directly contaminate the food and drink, and other people get infected after consuming the feces. 2. Oral-oral route: The infected person’s saliva with H. pylori contaminates food or utensils, and other people get infected after eating it. Some parents infected with H. pylori kiss their babies or feed their babies by mouth, which is also an oral route of transmission. H. pylori can be transmitted in these ways and is not airborne. If H. pylori infection is suspected, it is recommended to go to the hospital for H. pylori testing, and if H. pylori tests positive, it should be treated aggressively.
