Summary of COVID-19 outbreaks in Ottawa healthcare, childcare and educational establishments, based on the most up to date information available in the the Ontario Ministry of Health Public Health Case and Contact Management Solution (CCM) .

Accuracy: Points of consideration for interpretation of the data: The data was extracted by Ottawa Public Health from the Ontario Ministry of Health Public Health Case and Contact Management Solution (CCM) . The CCM is a dynamic disease reporting system that allows for ongoing updates to data previously entered. The data extracted from The CCM represent a snapshot at the time of extraction and may differ in previous or subsequent reports.Data are for confirmed outbreaks and the number of staff, living in Ottawa, and residents/patients/students with laboratory confirmed COVID-19 associated to each outbreak is provided. Please note, individuals may be linked to multiple outbreaks. All the outbreaks reflect the outbreak definitions at the time they were declared open:Healthcare Institutions: From April 1st 2020, 1 staff or resident case of laboratory-confirmed COVID-19 is considered an outbreak in long-term care homes (LTCH), retirement homes (RH) and other healthcare institutions (e.g. group home, assisted living, group shelter) and declared facility wide. Starting May 10th 2020, 2 staff or patient cases of laboratory-confirmed COVID-19 within a specified hospital unit within a 14-day period where both cases could have reasonably acquired their infection in hospital is considered an outbreak in a public hospital.Childcare & Education: Starting July 2020, 1 child or staff (or household member) case of laboratory-confirmed COVID-19 is considered an outbreak in a childcare establishment. Starting August 26 2020, 2 student or staff (or visitor) cases of laboratory-confirmed COVID-19 within a specified class within a 14-day period where at least one case could have reasonably acquired their infection at school (including transportation and before/after school care) is considered an outbreak in an educational establishment.

This dataset is subject to change. Please review the daily epidemiologic summaries for information on variables, methodology, and technical considerations. ##Cumulative Deaths **Effective November 14, 2024 this page will no longer be updated. Information about COVID-19 and other respiratory viruses is available on Public Health Ontario’s interactive respiratory virus tool: https://www.publichealthontario.ca/en/Data-and-Analysis/Infectious-Disease/Respiratory-Virus-Tool ** The methodology used to count COVID-19 deaths has changed to exclude deaths not caused by COVID. This impacts data captured in the columns “Deaths”, “Deaths_Data_Cleaning” and “newly_reported_deaths” starting with data for March 11, 2022. A new column has been added to the file “Deaths_New_Methodology” which represents the methodological change. The method used to count COVID-19 deaths has changed, effective December 1, 2022. Prior to December 1, 2022, deaths were counted based on the date the death was updated in the public health unit’s system. Going forward, deaths are counted on the date they occurred. On November 30, 2023 the count of COVID-19 deaths was updated to include missing historical deaths from January 15, 2020 to March 31, 2023. A small number of COVID deaths (less than 20) do not have recorded death date and will be excluded from this file. CCM is a dynamic disease reporting system which allows ongoing update to data previously entered. As a result, data extracted from CCM represents a snapshot at the time of extraction and may differ from previous or subsequent results. Public Health Units continually clean up COVID-19 data, correcting for missing or overcounted cases and deaths. These corrections can result in data spikes and current totals being different from previously reported cases and deaths. Observed trends over time should be interpreted with caution for the most recent period due to reporting and/or data entry lags. ##Related dataset(s) * Confirmed positive cases of COVID-19 in Ontario

Under the Ontario Health Protection and Promotion Act (HPPA), healthcare institutions (hospitals, long-term care homes and retirement homes) are required to monitor staff and patients/residents for signs and symptoms of gastroenteric (e.g., nausea, vomiting, diarrhea, fever) and respiratory (e.g., cough, runny nose, sore throat, fever) infections. Healthcare institutions must also actively look for, detect and report suspected and/or confirmed outbreaks to their local public health unit. An outbreak is defined as a localized increase (e.g. in an institution, or a specific ward or floor within an institution) in the rate of infection or illness, above that which is expected. Under the HPPA, Toronto Public Health is required to respond to reports of suspected and confirmed outbreaks of gastroenteric and respiratory illness. Toronto Public Health works with healthcare institutions to prevent and control institutional outbreaks, including the use of best practices in infection prevention and control. The most recent dataset is updated weekly on Thursdays with data as of the Wednesday at 2pm. Please note that all instances of "Coronavirus" in the datasets refer to the seasonal coronavirus, commonly identified as a causative agent for institutional respiratory outbreaks, and not COVID-19.

Background: Long-term care facilities had the highest rate of COVID-19 deaths in Canada; thus, it was essential to understand the effectiveness of vaccines and the risk factors for outbreaks in the elderly residents of long-term care and retirement homes. Aims of the CITF-funded study: This study aimed to 1) understand the association between outbreaks and features of long-term care and retirement homes; 2) determine the recurrence rate of outbreaks in homes that have been previously exposed; 3) describe residents’ immune response to infection and vaccination; and 4) estimate vaccine effectiveness in residents. Methods: This cohort study recruited residents from participating long-term care and retirement home across Ontario through invitations from research coordinators. Study visits occurred at participants’ first dose and second dose of the COVID-19 vaccine, and then 3 weeks, 3 months, 6 months, 9, and 12 months post- second dose. For those who got a third dose, follow up was done 3 weeks, 3 months, and 6 months after their third dose. Staff, essential visitors, and resident participants were followed up every week or per visit for saliva surveillance active COVID infection . A DBS whole blood sample was given at enrolment and at each follow up for serology testing. Contributed dataset contents: The datasets include 1261 participants who completed baseline surveys between January 2021 and July 2023. 90% of participants gave one or more blood samples between April 2021 and April 2023 for analysis. A total of 6078 samples were collected. Variables include data in the following areas of information: demographics (date of birth, sex, race-ethnicity, indigeneity), general health (weight and height, smoking, flu vaccination, chronic conditions), SARS-CoV-2 outcomes (positive test results, hospitalizations), SARS-CoV-2 vaccination, and serology (IgA, IgG, and IgM against SARS-CoV-2 receptor-binding domain (RBD) and spike (S) protein).

Effective June 7th, 2024, this dataset will no longer be updated.This file contains data on:

1. Cumulative count of Ottawa residents with laboratory-confirmed COVID-19 by episode date (i.e. the earliest of symptom onset, testing or reported date), including active cases and resolved cases.

2. Cumulative count of Ottawa residents with laboratory-confirmed COVID-19 who died by date of death.

3. Daily count of Ottawa residents with laboratory-confirmed COVID-19 by reported date and episode date.

4. Daily count of Ottawa residents with laboratory-confirmed COVID-19 by outbreak association and episode date.

5. Daily count of Ottawa residents with laboratory-confirmed COVID-19 newly admitted to the hospital, currently in hospital, and currently in the intensive care unit (ICU).

6. Cumulative rate of confirmed COVID-19 for Ottawa residents by age group and episode date.

7. Cumulative rate of confirmed COVID-19 for Ottawa residents by gender and episode date.

8. Daily count of Ottawa residents with laboratory-confirmed COVID-19 by source of infection and episode date.

Data are from the Ontario Ministry of Health Public Health Case and Contact Management Solution (CCM).

Accuracy: Points of consideration for interpretation of the data:

The percent of cases with no known epidemiological (epi) link, during the current day and previous 13 days, is calculated as the number of cases with no known epi link among all cases. The percent of cases with no known epi link is unstable during time periods with few cases.

Source of infection is based on a case's epidemiologic linkage. If no epidemiologic linkage is identified, source of infection is allocated using a hierarchy of risk factors: related to travel prior to April 1, 2020 > part of an outbreak > close or household contact of a known case > related to travel since April 1, 2020 > unspecified epidemiological link > no known source of infection > no information available.

Data are entered into and extracted by Ottawa Public Health from the Ontario Ministry of Health Public Health Case and Contact Management Solution (CCM). The CCM is a dynamic disease reporting system that allows for ongoing updates; data represent a snapshot at the time of extraction and may differ from previous or subsequent reports.

As the cases are investigated and more information is available, the dates are updated.

A person’s exposure may have occurred up to 14 days prior to onset of symptoms. Symptomatic cases occurring in approximately the last 14 days are likely under-reported due to the time for individuals to seek medical assessment, availability of testing, and receipt of test results.

Confirmed cases are those with a confirmed COVID-19 laboratory result as per the Ministry of Health Public health management of cases and contacts of COVID-19 in Ontario. March 25, 2020 version 6.0.

Counts will be subject to varying degrees of underreporting due to a variety of factors, such as disease awareness and medical care seeking behaviours, which may depend on severity of illness, clinical practice, changes in laboratory testing, and reporting behaviours.

Data on hospital admissions, ICU admissions and deaths are likely under-reported as these events may occur after the completion of public health follow up of cases. Cases that were admitted to hospital or died after follow-up was completed may not be captured in iPHIS or local health unit reporting tools.

Cases are associated with a specific, isolated community outbreak; an institutional outbreak (e.g. healthcare, childcare, education); or no known outbreak (i.e., sporadic).

The distribution of the source of infection among confirmed cases is impacted by the provincial guidance on testing.

Surveillance testing for COVID-19 began in long term care facilities on April 25, 2020.

Source of infection is allocated using a hierarchy: Related to travel prior to April 1, 2020 > Close contact of a known case or part of a community outbreak or source of infection is an institutional outbreak > Related to travel since April 1, 2020 > No known source of infection > Missing.

The percent of cases with unknown source, during the current day and previous 13 days, is calculated as the number of cases with no known source among cases who source of infection is not an institutional outbreak. Calculated over a 14 day period (i.e. the day of interest and the preceding 13 days). The percent of cases with no known source is unstable during time periods with few cases.
