Waterloo Region COVID-19 summary

Background

Region of Waterloo Public Health continues to work closely with local hospitals, health care partners, the Ministry of Health, Public Health Ontario and many community partners to respond to Novel Coronavirus (COVID-19) in Waterloo Region.

Cases in Waterloo Region

The COVID-19 data results presented below represent a snapshot of the cumulative totals at the time of reporting. The results will differ each day as new case information is available and the situation continues to change. We expect to update case information daily, Monday to Saturday, at 10:30 a.m. with data that are current as of 7 p.m. the previous day.

There are two date options for the epidemiological curve also known as an "epi-curve" graphs:

• By symptom onset date
• By case reported date

The epi-curve by symptom onset date shows a more accurate picture of the progression of the epidemic over time. Caution is needed when interpreting the most recent results, because there is a one to two week lag from when individuals get sick, to when cases are reported to Public Health. 

The epi-curve by case reported date shows the number of cases over time as they were reported to Public Health.

Outbreak-related cases are those associated with an outbreak in a congregate living setting such as a long term care home, retirement home or group home, as well as other outbreaks.

Community cases are those not associated with a specific outbreak. The transmission type may be close contact with another case, from travel, or an unknown source.

There is broad circulation of COVID-19 in our community. You should assume you could get COVID-19 anywhere in Waterloo Region.

Notes

• Municipal data:

  • Cases are presented by municipality based on home residence. The graph presents the rate (number of cases per 100,000 population) and the number of cases per municipality can be seen by hovering your cursor over each bar in the graph.

  • The number of positive cases in each municipality is skewed based on testing guidance that prioritizes groups and settings at greater risk, including long-term care and retirement homes.

  • There is broad circulation of COVID-19 in our community. You should assume you could get COVID-19 anywhere in Waterloo Region.

• Outbreak data:

  • Facility outbreaks are defined as one or more resident or staff case(s).

  • Staff cases may include some staff who reside outside of Waterloo Region.

  • Congregate settings are defined as group homes and community supported living settings, and disability-specific congregate settings.
  • Congregate setting data is aggregated to protect the privacy of individuals, as many facilities have a small number of residents and staff.
  • Workplace outbreak data will be refreshed every Tuesday and Friday.
  • Hospital outbreaks are declared by area hospitals, in consultation with Region of Waterloo Public Health.
