What Is H. Pylori?

2. Epidemiology

H. pylori infection has been linked to race. For example, 60% of cases were observed to occur in Hispanics while only 29% occur in Caucasians. Internationally, it is a common organism and can be found in up to 50% of the population. In patients with peptic ulcer disease, as many as 90% have found to have H. pylori infection. However, there are fewer than 15% of individuals with H. pylori infection that experience peptic ulcer disease. Another study reported that Caucasians are found to be less frequently infected at approximately 20% compared to 54% in African Americans and 60% in Hispanics. Although both gender are affected equally, females have a higher incidence of reinfection compared to males. The infection can occur at any age and is acquired most frequently during childhood.
