Gastroenteritis From Rotavirus Infection in Brazilian Children Less Than 5 Years of Age (Study V260-031).

Study Overview
=================
Brief Summary
-----------------
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.

| --- | --- |
| Brazilian Children With Rotavirus Gastroenteritis<br>Brazilian children under 5 years of age who have diarrhea attributed to rotavirus located in 4 hospitals from 4 different Brazilian regions | Biological: Rotavirus Vaccine<br>* 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.<br>|

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| 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. | 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. | 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. | 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. | 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. | 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. | 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. | 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. | 1 year |
