TL;DR: In this article, the authors performed quantitative polymerase chain reaction for multiple enteropathogens on 878 acute watery diarrheal stools sampled from 14643 episodes captured by surveillance of children <5 years of age during 2013-2014 from 16 countries.
Journal ArticleDOI

TL;DR: From 2009 to 2013 the diversity of noroviruses in children hospitalized with gastroenteritis in South Africa was investigated and the most comprehensive recent data on NoV diversity in Africa is presented.
Journal ArticleDOI
Sapovirus prevalence in children less than five years of age hospitalised for diarrhoeal disease in South Africa, 2009-2013

TL;DR: Determinants increasing the odds of SaV included overcrowding and concomitant infections while HIV-infected children with SaV displayed bloody stools, low birth weight and reduced access to proper sanitation.
Journal ArticleDOI
Diverse sapovirus genotypes identified in children hospitalised with gastroenteritis in selected regions of South Africa
TL;DR: This study has provided the first comprehensive data on the genetic diversity of SaV genotypes in a clinical setting in SA, contributing to the global knowledge of this virus.
Journal ArticleDOI
