If you live with a person who has the H. Pylori infection, the chances of you getting it are much higher. The reason for this is that it is thought that the H. Pylori bacteria is spread through human contact. Saliva and feces are two of the common ways that this bacteria is spread. A person who is in close contact with another person who has been infected by this bacteria will likely develop the infection as well.
Of course, one person may develop symptoms of the infection while the other does not. If you are living with someone who has H. Pylori infection it might be a good idea to start antibiotics along with them so that the infection does not get worse or cause any symptoms in you as well. Probiotics can also help add good bacteria back into your gut and digestive system, which can counteract the symptoms of an H. Pylori infection.
