H. Plyori Incidence Rate
To understand the incidence rate of H. pylori in the United States and throughout the world.
- "The [H. pylori] infection is generally acquired during childhood but can remain asymptomatic" into adulthood.
- H. pylori can lead to a number of conditions such as "chronic gastritis, gastric cancer, gastric adenocarcinoma, mucosa-associated lymphoid tissue (MALT), lymphoma, and peptic ulcer disease".
- "The mode of transmission for H. pylori is not certainly known; however, epidemiological studies strongly support person-to-person transmission and fecal-oral and oral-oral routes."
- Throughout the world, over 50 percent of the population is infected with the H. pylori bacteria.
- The infection is more common in developing nations, with the rate reaching 90 percent among children in some countries, compared to between 1.8 and 65 percent in developed countries.
- In the country of Kampala, the incidence rate is 43.3 percent overall.
- Overall, Africa has the highest incidence rate of H. pylori, while Oceania has the lowest.
- "Among individual countries, the prevalence of H pylori infection varied from as low as 18.9 percent in Switzerland...to 87.7 percent in Nigeria."
- In the U.S., the H. pylori incidence rate was higher in the African American, Hispanic, and elderly communities as of 2010.
- Specifically, the incidence rate was 60 percent in the Hispanic community and 54 percent among African Americans, compared to 20 percent in white Americans.
- Additionally, "estimated prevalence is 20 percent for people younger than 30 years and 50 percent for those older than 60 years" in the United States.
