High Exposure, Spontaneous Clearance, and Low Incidence of Active <i>Helicobacter pylori</i> Infection: The Sorbo San Basile Study

Abstract

H. pylori infection is highly dynamic with wide range of spontaneous clearance. It is easily cleared in the first decades of life, more recent years, less crowded homes, and males. It disappears and recurs more often than it was previously thought, implying that the current decline in its prevalence is due to real clearance instead of a fall in infection rate.
