Multiplex PCR reveals a high prevalence of multiple pathogens in traveller's diarrhoea in children.

Objective: Traveller's diarrhoea (TD) is one of the most frequent illnesses affecting children returning from tropical countries. The purpose of this study was to assess the distribution of pathogens associated with TD in children using a multiplex PCR assay on stool samples.

Design: All the children admitted for TD in two university hospitals from 1 August to 15October during 2014 and 2015 were included in a prospective study.
