<jats:title>SUMMARY</jats:title><jats:p>Non-typhoidal <jats:italic>Salmonella</jats:italic> are an important but poorly characterized cause of paediatric diarrhoea in developing countries. We conducted a hospital-based case-control study in children aged &lt;5 years in Ho Chi Minh City to define the epidemiology and examine risk factors associated with <jats:italic>Salmonella</jats:italic> diarrhoeal infections. From 1419 diarrhoea cases and 571 controls enrolled between 2009 and 2010, 77 (5·4%) diarrhoea cases were stool culture-positive for non-typhoidal <jats:italic>Salmonella</jats:italic>. <jats:italic>Salmonella</jats:italic> patients were more likely to be younger than controls (median age 10 and 12 months, respectively) [odds ratio (OR) 0·97; 95% confidence interval (CI) 0·94–0·99], to report a recent diarrhoeal contact (8·1% cases, 1·8% controls; OR 5·98, 95% CI 1·8–20·4) and to live in a household with &gt;2 children (cases 20·8%, controls 10·2%; OR 2·32, 95% CI 1·2–4·7). Our findings indicate that <jats:italic>Salmonella</jats:italic> are an important cause of paediatric gastroenteritis in this setting and we suggest that transmission may occur through direct human contact in the home.</jats:p>
