  To describe the epidemiological and clinical characteristics of acute gastroenteritis according to their etiology (rotavirus or other) in children younger than 5 years old in a private institution in the City of Buenos Aires.
  
  
  
  to analyze related costs.
  
  
  
  Cross sectional, descriptive, observational study conducted during one year in children younger than 5 years old with gastroenteritis. The presence of rotavirus was diagnosed with the VIKIA® Rota-Adeno test. Demographic, clinical and immunization data were collected. A univariate data analysis was performed.
  
  
  
  A total of 275 patients were included; 18.5% of them were R+. Rotavirus was more common in children younger than 2 years old and in the period between March and June. The cases of rotavirus gastroenteritis were more severe, required more hospitalizations (OR 2.07; 95% CI 1.17-7.13), and resulted in higher costs. In the sample studied, the immunization outcome measure reduced the risk of rotavirus infection.
  
  
  
  Acute gastroenteritis caused by rotavirus were different from other etiologies in that they had a seasonal peak and in relation to the median age of patients, the severity of the condition, the association with hospitalization and the increase in costs.
