High Prevalence of Helicobacter pylori-Induced Gastritis in China: Results of a Screening Study in 194 Adolescents
Helicobacter pylori (HP) infection has been reported in populations all over the world. Whereas the direct source of infection is still unknown, there is increasing evidence that HP is spread via a contaminated water or food supply . The prevalence of HP infection in the general population is correlated to the socioeconomic status and standard of hygiene in specific subpopulations. In some countries up to 90% of healthy adults may be infected [2, 3]. In Western countries the prevalence of HP infection increases with age and reaches a plateau at about 50%.
