Barriers to Community-Based Eradication of Helicobacter pylori Infection.

Helicobacter pylori (HP) is a causative agent in gastric cancer (GC). In the United States, HP is more prevalent in racial and ethnic minorities, including African Americans, Asian Americans, Latinos, and immigrants, the same groups that are more likely to develop and die from GC. Although screening for HP is not presently performed in the United States, there are plausible benefits to doing so, because HP is considered a group 1 carcinogen by the World Health Organization, and its link to GC parallels that of human papilloma virus and cervical cancer.
