What is the significance of Helicobacter pylori?
HELICOBACTER PYLORI: SIGNIFICANCE IN THE DEVELOPING WORLD In adults H. pylori is the principal cause of duodenal ulcer disease, and there is epidemiological evidence of an association with gastric cancer.

How long does it take for H. pylori symptoms to show?
INCUBATION PERIOD: Unclear as symptoms usually do not appear until adulthood and observable symptoms may never develop (known as silent infections) (14). Major symptoms such as abdominal pain, heartburn, and nausea have been observed 3 – 4 days after ingestion of the bacteria (15).
