The document presents the results of an epidemiological and clinical study of rotavirus diarrhea in children under 5 years old who were treated at medical centers in Miranda State, Venezuela between 2006 and 2007, finding that 19% of cases were infected with rotavirus which was associated with more severe symptoms like vomiting and malnutrition compared to rotavirus negative cases. The study also found differences between hospital and outpatient clinics in factors like socioeconomic status, malnutrition, dehydration, and rotavirus infection rates.
