I think; It does.

yes dear prof.

Helicobacter pylori in relation to Stomach cancer

There is researches about >>>> ** Recommended Vaccination …

For the general population, the most likely mode of transmission is from person to person, by either the oral-oral route (through vomitus or possibly saliva) or perhaps the fecal-oral route. The person-to-person mode of transmission is supported by the higher incidence of infection among institutionalized children and adults and the clustering of H. pylori infection within families. Also lending support to this concept is the detection of H. pylori DNA in vomitus, saliva, dental plaque, gastric juice, and feces. Waterborne transmission, probably due to fecal contamination, may be an important source of infection, especially in parts of the world in which untreated water is common. Recent studies in the United States have linked clinical H. pylori infection with consumption of H. pylori-contaminated well water.

I think a multicenter study should be planned.

I agree with your interesting suggestion

What's the prevalence of HP positivity in your country?

What etiopathogens take play a role in H Pylori infection?

The mean actual prevalence is 40-45% of the general population

It is reported 80% in Turkey. A non-invasive family practitioners' research on HP positivity can be suggested.

What about Northern part of Europe?

What about Arabic countries?
