Important notes about the data
  • Newly confirmed cases will show up initially under the WDG Region total. However, it can take up to several days to confirm a case’s home address, and only then will that positive case be assigned to a region/municipality and show up as an active case for that area. This means totals will not always add up each day - for example, total cases in WDG Region may not equal the total cases for each area added together (Wellington+Dufferin+Guelph). Keep in mind, case totals do not tell the whole story and you should assume you could get COVID-19 in any community.
  • In order to protect the health information of individuals, the data presented is aggregate data from the region.
  • WDG Region includes all of Wellington County, Dufferin County and the City of Guelph.
  • The number of reported cases and detailed information on each case is in a state of flux and may be received at different times. Expect that totals may not be consistent because some information will be pending each time the numbers are refreshed (ie. total confirmed cases vs. patient status case totals may not always add up to the same number).
  • Confirmed cases with unknown addresses are excluded from counts by region (Wellington, Dufferin and City of Guelph), as they are unable to be assigned to a specific area.
  • The Public Health Case and Contact Management System (CCM) is an information system for the reporting and surveillance of Diseases of Public Health Significance (DOPHS) in Ontario.
    • Data in the interactive status report is taken from confirmed cases reported to date in CCM.
    • Resolved cases include cases reported as recovered in CCM, cases that are not currently listed as hospitalized in CCM, and cases that are 14 days past symptom onset (if present) or 14 days past the episode date if the case is closed.
  • Declaring an Outbreak in LTCH/RH:
    • A suspect outbreak in a home is defined as one lab-confirmed COVID-19 case in a resident.
    • A confirmed outbreak in a home is defined as two or more lab-confirmed COVID-19 cases in residents and/or staff (or other visitors) in a home with an epidemiological link, within a 14-day period, where at least one case could have reasonably acquired their infection in the home.
      • Examples of reasonably having acquired infection in a home include:
        • No obvious source of infection outside of the LTCH setting; OR
        • Known exposure in the LTCH setting.

  • The number of confirmed cases is only part of the picture. Changes in testing criteria and volume will affect the trends seen on the charts, therefore those trends may not necessarily reflect changes in the actual number of infected people in the population.
