Hi Adrin

Firstly, please be selective with your language in the future as this is a public platform.

H.pylori may have been existing for a long period of time. It can be passed through a number of ways that are not as obvious as with other infectious causes. Trying to isolate HOW you picked up the infection can be frustrating so rather focus on the treatment. In the past, the focus was always on the fact that H.pylori was more easily contracted in developing nations but even in developed countries, H.pylori infection is common. There may be a genetic predisposition to this microorganism which may explain why some people do not get infected with it.
