This is a 1-year study evaluating hospitalizations and the medical care for the treatment of diarrhea from rotavirus infection in children \< 5 years of age, conducted in four hospitals located in four Brazilian regions. A stool sample from each eligible child passing 3 or more loose stools or watery stools within a period of 24 hours and requiring hospitalization or rehydration therapy (oral or IV rehydration) will be tested for the presence of rotavirus, using standard laboratory procedures (ie, Enzyme Linked Ligand Sorbent Assay, or ELlSA) by all participating hospitals.

This is an observational study evaluating hospitalizations and the medical care for the treatment of diarrhea from rotavirus infection in children \< 5 years of age; however, any rotavirus vaccines used in the children presenting with rotavirus-attributed diarrhea were evaluated, as well the prevalent rotavirus serotypes in this sample for future vaccine development.
The Number of Hospitalizations for Diarrhea in Children up to 5 Years of Age
The total number of hospitalizations for diarrhea in children up to 5 years of age in the 4 Brazilian hospital research centers was reported. Diarrhea was defined as the passage of 3 or more soft/liquid feces in a 24-hour period.
Time frame: 1 year
The Percentage of Hospitalizations for Diarrhea in Children up to 5 Years of Age
The percentage of total hospitalizations for children up to 5 years of age in the 4 Brazilian hospital research centers that were for diarrhea. Diarrhea was defined as the passage of 3 or more soft/liquid feces in a 24-hour period.
Time frame: 1 year
The Geographic Distribution of Hospitalizations for Diarrhea That Are Caused by Rotavirus
Children up to 5 years of age hospitalized for diarrhea were tested for fecal rotavirus as determined by enzyme immunoassay. Diarrhea was defined as the passage of 3 or more soft/liquid feces in a 24-hour period. For each geographic location, the number of hospitalizations for diarrhea that was caused by rotavirus was reported.
Time frame: 1 year
The Percentage of Hospitalizations for Diarrhea That Are Caused by Rotavirus
Children up to 5 years of age hospitalized for diarrhea were tested for fecal rotavirus as determined by enzyme immunoassay. Diarrhea was defined as the passage of 3 or more soft/liquid feces in a 24-hour period. The number of hospitalizations for diarrhea from rotavirus infection was divided by the total number of hospitalizations for diarrhea in the 4 hospital research centers.
Time frame: 1 year
The Number of Hospitalizations for Diarrhea That Are Caused by Rotavirus by Age Group
Children up to 5 years of age hospitalized for diarrhea were tested for fecal rotavirus as determined by enzyme immunoassay. Diarrhea was defined as the passage of 3 or more soft/liquid feces in a 24-hour period. The number of hospitalizations for diarrhea from rotavirus infection was reported for each age group.
Time frame: 1 year
The Numbers of Participants Hospitalized for Diarrhea and Rotavirus-caused Diarrhea Per Month
Children up to 5 years of age hospitalized for diarrhea were tested for fecal rotavirus as determined by enzyme immunoassay. Diarrhea was defined as the passage of 3 or more soft/liquid feces in a 24-hour period.
Time frame: 1 year
The Duration of Hospitalization for Participants Enrolled in the Study
The mean duration (days) of hospital stay for children up to 5 years of age hospitalized for diarrhea in the 4 Brazilian hospital research centers. Diarrhea was defined as the passage of 3 or more soft/liquid feces in a 24-hour period.
Time frame: From hospital admission to discharge
The Number of Deaths in Hospitalized Participants Enrolled in the Study
The number of deaths among children up to 5 years of age hospitalized for diarrhea in the 4 Brazilian hospital research centers. Diarrhea was defined as the passage of 3 or more soft/liquid feces in a 24-hour period.
Time frame: 1 year
