Mixed viral infections in children with acute diarrhoea

To the editor: Respiratory infections (RI) and acute diarrhoea (AD) are the main causes of morbidity and mortality among Mexican children. A retrospective analysis of rotavirus (RV) epidemics in Merida, Mexico from 2003 to 2008 indicates that 31.5% of children with diarrhoea also present respiratory symptoms. We hypothesized that the co-occurrence (mixed clinical symptoms) of RI and AD may also be a result of mixed diarrheal and respiratory viral infections in children. To address this possibility we evaluated the presence of different respiratory viruses in children diagnosed with acute diarrhoea in two slums with poor housing and health conditions in Merida.
