Locals get travellers’ diarrhoea too: risk factors for diarrhoeal illness and pathogenic Escherichia coli infection across an urban‐rural gradient in Ecuador

Abstract:

Objectives Diarrhoea is a common and well‐studied cause of illness afflicting international travellers. However, traveller's diarrhoea can also result from travel between high and low disease transmission regions within a country, which is the focus of this study. Methods We recruited participants for a case‐control study of diarrhoea at four sites along an urban‐rural gradient in Northern Ecuador: Quito, Esmeraldas, Borbón and rural communities outside of Borbón.

Travel to Quito was associated with diarrhoea (aOR = 2.01, 95% CI = 1.10–3.68) and travel to Guayaquil (another urban …
