-Background -Helicobacter pylori infection presents high prevalence in developing countries

ELISA method had good sensitivity in children older than 10 years, using the cutoff 5 U/mL, but the specificity was low.

The study evaluated the prevalence of Helicobacter pylori infection in toddlers using the stool antigen test. Helicobacter pylori was detected in 28/113 (13.1%). Crowding and age were risk factors significantly associated to the infection. We conclude there is a low prevalence of the infection in the studied children.
