Typically acquired in early childhood, its transmission is closely linked to socio-economic disadvantage and overcrowding. Although most infected children are asymptomatic, some develop epigastric pain, dyspepsia, weight loss, or other gastrointestinal disturbances. Chronic infection may eventually lead to mucosal atrophy and intestinal metaplasia, increasing the risk of gastric cancer later in life.

Recent adult studies indicate that stool-based P
