Overview
Approximately two-thirds of the world's population is infected with H. pylori. In the United States, H. pylori is more prevalent among older adults, African Americans, Hispanics, and lower socioeconomic groups.
Approximately 25 million Americans suffer from peptic ulcer disease at some point in their lifetime. Each year there are 500,000 to 850,000 new cases of peptic ulcer disease and more than one million ulcer-related hospitalizations.
Epidemiology and Demographics
Prevalence
- H.pylori inhabits more than 50% of world's population especially in developing countries.[1]
- The prevalence of H.pylori infection in developing countries is higher than that in developed countries.
Incidence
Mortality rate
Age
The prevalence of infection increases with age.[2]
- About 30%-50% of H.pylori infections are acquired during childhood which increases to 90% during adulthood in developing countries.[3]
Gender
Race
Developing countries
- The prevalence of H.pylori is higher in developing countries than that in developed countries.
Developed countries
