<i>Helicobacter pylori</i> Status and Symptom Assessment Two Years after Eradication in Pediatric Patients from a High Prevalence Area

Abstract

The 12.8% per year reinfection rate in childhood at 2 years that we observed should prompt a re-evaluation of H. pylori status even after a successful eradication. Living in an H. pylori high prevalence area increases the annual risk of reinfection by approximately fourfold over the annual risk in H. pylori low prevalence areas.
