Surveillance for COVID-19 Variants

PEI contributes data to the national reporting of COVID-19 variants in Canada

 

Wastewater Surveillance 

PEI’s Chief Public Health Office and the Department of Environment, Energy and Climate Action have partnered with the municipalities of Alberton, Charlottetown (including Stratford), Montague, Souris, and Summerside, and the National Microbiology Laboratory in Winnipeg to implement wastewater surveillance for COVID-19 in PEI.
PEI wastewater testing results are included on the national COVID-19 wastewater surveillance dashboard

Technical Notes

COVID-19 case count includes individuals who tested positive on lab-based PCR, Abbott ID Now NAAT, and Lucira NAAT.  It does not include individuals that tested positive on a rapid antigen test.

Note that clinical diagnosis of influenza takes place frequently in the community during peak season and is not confirmed with laboratory testing. In contrast to COVID-19, the prescribing of anti-viral treatment for influenza does not require a positive influenza test and can be based on a clinical diagnosis alone. Given the differences in testing approaches, the number of influenza detections and the number of COVID-19 detections in a given time period are not directly comparable.

COVID-19, influenza and RSV case counts are just an indication of greater respiratory illness activity as many individuals with respiratory illness do not seek medical attention.

Test positivity = ^{(Count of positive tests per reporting period)} / ^{(Count of total tests per reporting period)  ×100}

Test positivity for COVID-19 includes lab-based PCR and Abbott ID Now NAAT.  For influenza and RSV, test positivity includes lab-based PCR. Cases among PEI residents diagnosed outside of the province are included in the case counts but are excluded from the percent positivity calculation.

Paxlovid dispenses will only be reported when there’s at least 10 dispenses during the reporting period.

Outbreak definitions
    -Influenza

• Laboratory-confirmed influenza outbreak: two or more cases of influenza like illness (ILI) within a seven-day period with an epidemiological link, including at least one laboratory confirmed case of influenza within a surveillance setting
• ILI outbreak: two or more cases of ILI within a seven-day period
• ILI outbreak in school or workplace: Greater than 10% absenteeism which is likely due to ILI

    -COVID-19 outbreak

• 2 or more test-confirmed cases of COVID-19 which are epidemiologically linked to a specific setting or location

    -RSV

• 2 or more cases of ILI within a seven-day period with an epi link, including at least one laboratory confirmed case of RSV within a surveillance setting

Hospitalization definition: a laboratory confirmed case of influenza/RSV or test-confirmed case of COVID-19 that received treatment in hospital as a result of their respiratory illness

ICU admission definition: a case of influenza, RSV or COVID-19 that meets the hospitalization definition and was admitted to the ICU

Death definition: a death resulting from a clinically compatible illness in a laboratory confirmed influenza/RSV case or test-confirmed COVID-19 case. A death due to influenza/COVID-19/RSV may be attributed when influenza/COVID-19/RSV is the cause of death or is a contributing factor. 

Test-confirmed COVID-19 case: case with a positive result on lab-based PCR, Abbott ID Now NAAT, or Lucira NAAT.  A case with a positive result on a rapid antigen test may be considered to be a test-confirmed case of COVID-19 upon review by a Chief Medical Officer of Health or relevant public health authority.  

Hospitalization data is gathered through infection prevention and control practitioners at each Island hospital.

Hospitalizations, ICU admissions, and deaths are reported based on the date that they are reported to the Chief Public Health Office.

Data presented throughout the report may be updated retroactively as new data becomes available.
