ABSTRACT

Helicobacter pylori ( Hp) is one of the most common infectious pathogens with a high infection rate and recurrence rate in humans worldwide.In developing countries , the prevalence of Hp infection can be up to 90%and its recurrence rate is also much higher than that in developed countries.The recurrence of Hp infection is either due to recrudescence or reinfection.Compared with reinfection , the time window for recrudescence is generally shorter.Recrudescence is generally considered as the recurrence of Hp infection within one year after eradication , followed by the recurrence of Hp-associated diseases shortly.This article reviews the factors related to Hp recrudescence.
