[Epidemiology of H. pylori infection and exploration of its infection route].
To build up a preventive strategy for H. pylori related diseases including gastric cancer, infection ages and routes are important. Recently, several studies have explored them. In advanced countries, most infections occur under five years of age. Mother to child in some studies and sibling to sibling in others were dominant infection routes. As infection ages and routes depend on countries, studies in Japan are indispensable. Infection in kindergartens, nursery and elementary schools as well as in families should be explored. Based on the findings, a strategy preventing infection to children should be build up to prevention H. pylori related diseases.
