How can you get Helicobacter pylori (H. pylori)?

ANSWER

These spiral-shaped bacteria get into your body through your mouth. Then, they burrow into the mucus that lines your stomach.

You can pick up an H. pylori infection in several ways. The bug can be in food or water that isn't handled in a clean, safe way. You can get it from mouth-to-mouth contact with someone who has it. You also can get it if you come into contact with the vomit or feces of someone who's infected.
