Rotavirus SurveillanceCanadian Rotavirus Surveillance Through the Immunization Monitoring Program Active (IMPACT)

There are two parts to this criteria- Hospital admission surveillance (to December 31, 2019); and genotype surveillance (to December 31, 2020)

Hospital admission surveillance:

Inclusion Criteria:

• Age 0 to 16 years of age.
• Inpatient status at the IMPACT hospital
• Acute onset of symptoms of acute gastroenteritis with or without diarrheal stools, with or without vomiting, with or without fever.
• Laboratory confirmation of rotavirus in stool specimens or autopsy tissue sample with the use of antigen detection methods (enzyme linked immunoassay \[ELISA\] or immunochromatographic methods) or electron microscopy or molecular (PCR) diagnosis in a stool specimen taken within 14 days after the onset of gastrointestinal symptoms. Cases identified by autopsy must have had gastrointestinal symptoms before death.
• Referred cases of rotavirus infections that have laboratory confirmation from another institution using the same criteria as above

Exclusion criteria

• Non-laboratory confirmed diagnosis.
• Clinical data is not accessible to the nurse monitor.
• Incidental findings of rotavirus in patients admitted to hospital without acute gastrointestinal symptoms.

Rotavirus Genotype Surveillance - on stool sample already obtained for hospital admission purposes (not additional for the surveillance).

- Rotavirus identification: Rotavirus identification at sites will be accomplished by rotavirus antigen detected by EIA (Enzyme Immuno Assay) or electron microscopy.
