Summary 

The Global Enteric Multicenter Study (GEMS) was a multi-country case-control study of diarrheal diseases in children under five years of age. GEMS-1A was a follow-up to the original GEMS-1 study, and took place in all of the original seven sites in Africa and Asia with enrollment from November 2011 through November 2012. Whereas GEMS-1 studied children under five years of age diagnosed with mid-to-severe diarrhea (MSD), GEMS-1A consisted of two parallel case-control studies: one study enrolled children under five years of age with MSD, and a separate study enrolled children over the age of five with less-severe diarrhea (LSD). In this way, GEMS-1A could compare cases of MSD with cases of LSD. 

In the Gambia, while enrollment ended in November 2012, follow-up visits were conducted through January 2013.
