Описание
Inclusion Criteria:
For SGE subjects:
- A male or female child aged 12 weeks to < 5 years at the time of hospital admission/ ED stay. The subject becomes ineligible on the fifth birthday.
- Subject admitted to (or who will have an ED stay at) the study hospital(s) for SGE during the study period.
- Onset of SGE ≤ 14 days prior to admission/ ED stay.
- Written/thumb printed informed consent obtained from the parent(s)/legally acceptable representative(s) (LAR (s)) of the subject.
For Cases:
• Laboratory confirmed (i.e. by ELISA) RV-positive stool sample collected at hospital admission/ ED stay or during the first 48 hours of hospitalisation.
For Controls:
- Subject admitted to (or who will have an ED stay at) the same study hospital(s) for SGE as that of the case during the study period.
- Laboratory confirmed (i.e. by ELISA) RV-negative stool sample collected at hospital admission/ ED stay or during the first 48 hours of hospitalisation.
- Subjects born within ± 2 weeks from the date of birth of the case.
Exclusion Criteria:
For SGE subjects:
- Child in care.
- Hospitalisation is unrelated to GE.
- Onset of SGE > 48 hours after admission to (or ED stay at) the hospital.
- Subject has digestive tube anomalies, chronic gastrointestinal disease or uncorrected congenital abnormalities.
- Subject with immunodeficiency.
- Subjects who live out of the federative entity where hospital(s) are located.

Cases
Children hospitalised for SGE, aged 12 weeks to < 5 years at the time of hospital admission/ED stay and whose stool samples test positive for RV by enzyme linked immunosorbent assay (ELISA) at a GSK designated laboratory.
|
Stool samples will be collected from all children enrolled in the study, within 48 hours of admission to the hospital/ ED.
Stool samples will be tested to determine the presence or absence of rotavirus (RV).
Additionally, for RV-positive cases, the stool samples will be tested to determine the RV genotypes.
|
|
Controls
Children hospitalised for SGE, aged 12 weeks to < 5 years at the time of hospital admission/ ED stay, whose stool samples test negative for RV by enzyme linked immunosorbent assay at a GSK designated laboratory and who will be matched to the cases by date of birth and the hospital of admission/ ED stay.
|
Stool samples will be collected from all children enrolled in the study, within 48 hours of admission to the hospital/ ED.
Stool samples will be tested to determine the presence or absence of rotavirus (RV).
Additionally, for RV-positive cases, the stool samples will be tested to determine the RV genotypes.
