Requirements to replace Ontario PHU datasets with the Ontario Ministry of Health dataset #97

jeanpaulrsoucy · 2022-02-03T01:26:54Z

Over the last few weeks, we have been forced to retire some Public Health Unit (PHU) datasets for Ontario which we have relied on since April 1, 2020. The first to fall was Chatham-Kent:

Chatham-Kent (ON) was rewritten (cases, deaths, recovered) back to 2020-04-01 using the Ontario Ministry of Health dataset. Previously we used the PHU’s dashboard, as we do for all other PHUs. However, there are significant discrepancies in cases, deaths and recovered between these two data sources, which made rewriting the whole time series the least disruptive option to the trends in the data.

This was done due to changes in reporting as a result of changes to PCR testing criteria in Ontario as of 2022. These changes in reporting have been replicated across most PHUs, but most changes have allowed us to continue reporting cases, deaths and recovered data as before. However, frequency of reporting has declined for some PHUs.

We have decided on the following criteria for retiring a PHU dataset and replacing it with the Ministry of Health dataset for that specific PHU:

Changes to data reporting such that cases, mortality and/or recovered cannot be reported as before, OR
Frequency of reporting drops below 3 times per years

We have decided that retiring 10 PHU datasets (out of 34) will trigger the archiving of all ON PHU datasets and the wholesale replacement of the ON case, mortality and recovered time series with the Ontario Ministry of Health dataset. At the moment, the following ON PHU datasets have been retired:

Chatham-Kent
Leeds, Grenville & Lanark
Eastern
Huron Perth
York
Grey-Bruce
Lambton
Haliburton Kawartha Pineridge
Durham

DATA NOTES: - IMPORTANT NOTICE: Due to recent changes in the availability of COVID-19 testing, case counts can no longer be considered a reliable indicator of spread. - Deaths in Hastings Prince Edward (ON) have declined. This decline, along with the other recent decline, appear to be due to the removal of deaths that they claim are unrelated to COVID-19. - Recovered in MB has declined for an unknown reason. - See notice in “RECENT CHANGES” section below regarding NS cases since 2021-12-10. - See notice in “RECENT CHANGES” section below regarding PE cases since 2021-11-02. NOTICE: Most of our data collection is automated. PLEASE CONTACT US REGARDING ANY ERRORS YOU MAY FIND. https://opencovid.ca/contact-us/ NEWS RELEVANT TO COVID-19 DATA: N/A RECENT CHANGES TO THE DATASET: BC recovered: BC has removed information on recovered cases, thus this will now be calculated as total cases - active cases - deaths. PE recovered: From now on, recovered values will be calculated as total cases - active cases - deaths, based primarily on the data provided in the daily press releases. This value has been recalculated back to the date of the first reported deaths in PEI (2022-01-14). [UPDATE, 2022-01-31: As of today, it appears that PEI is now appropriately accounting for deaths in the recovered value posted to their dashboard.] NS is again reporting the number of doses administered (1st, 2nd, 3rd) on their dashboard, which will be used going forward. Some ON Public Health Unit (PHU) datasets have been retired and replaced with the Ontario Ministry of Health dataset, rewriting their cases, mortality and recovered datasets back to 2020-04-01. You can track this here: #97 NU cumulative testing number has been replaced by the time series of tests completed from the Public Health Agency of Canada (https://health-infobase.canada.ca/covid-19/epidemiological-summary-covid-19-cases.html). The reason for this is that the previously reported value, number of people tested, somehow decreased by ~80% and has not been corrected for several days. Since 2021-11-02, cases and recovered for PE have been based on the number of cases reported by PHAC on weekdays (https://health-infobase.canada.ca/covid-19/epidemiological-summary-covid-19-cases.html) and the daily press releases on weekends (https://www.princeedwardisland.ca/en/news), as the PHAC dataset is not updated over the weekend. This change is due to the very inconsistent updating of the usual data source, the PEI dashboard (https://www.princeedwardisland.ca/en/information/health-and-wellness/covid-19-testing-and-case-data). The data reported by PHAC seems to match the data reported in press releases. [Note that historical values for 2021-11-02 to 2021-12-20 were re-calculated on 2021-12-20. 2021-11-02 was selected because it was not too far back and there was agreement in the number of cumulative cases reported by PHAC and the province on this day (319).] [GitHub issue #89] Additional doses (booster doses, 3rd doses, 4th doses) doses are now being reported for most provinces in a new dataset: vaccine_additionaldoses_timeseries_prov / vaccine_additionaldoses_timeseries_canada.csv First doses may be calculated as: total doses administered – vaccine completion (2nd doses) – additional doses. README on GitHub has been updated to provide a better description of the dataset: https://github.com/ccodwg/Covid19Canada ON DATA NOTE: As of 2021-09-07, active cases for ON should be correctly reported. Note that this has resulted in a major discontinuity for recovered and active cases for ON on 2021-09-07. Our case and mortality data from ON have been sourced from individual PHU websites (rather than the provincial MOH dataset) since April 1, 2020. However, the recovered number continued to be sourced from the MOH. As the PHU and MOH datasets diverged (several thousand cases were never confirmed and thus not included in the MOH datasets), this resulted in an inflated active case count for the province (daily differences were more or less reliable). On 2021-09-07, we transitioned to using recovered numbers directly from the PHUs; thus, active cases should now be correctly reported for ON. Additionally, 13 cases were added to Haliburton Kawartha Pineridge (ON) on 2021-09-07 to maintain consistency with the corrected recovery calculation. We regret the inconvenience. DATA NOTE FOR SK: As of 2020-12-14, we are providing a daily version of the official SK dataset that is compatible with the rest of our dataset in the folder official_datasets/sk. See below for information about our regular updates. A REPLACEMENT DATASET IS IMMINENT. SK transitioned to reporting according to a new, expanded set of health regions on 2020-09-14. Unfortunately, the new health regions do not correspond exactly to the old health regions. Additionally, the provided case time series using the new boundaries do not exist for dates earlier than August 4, making providing a time series using the new boundaries impossible. For now, we are adding new cases according to the list of new cases given in the “highlights” section of the SK government website (https://dashboard.saskatchewan.ca/health-wellness/covid-19/cases). These new cases are roughly grouped according to the old boundaries. However, health region totals were redistributed when the new boundaries were instituted on 2020-09-14, so while our daily case numbers match the numbers given in this section, our cumulative totals do not. We have reached out to the SK government to determine how this issue can be resolved. We will rectify our SK health region time series as soon as it becomes possible to do so.

See the following for more details: https://www.saskatchewan.ca/government/news-and-media/2022/february/03/living-with-covid-transition-of-public-health-management BC recovered: BC has removed information on recovered cases, thus this will now be calculated as total cases - active cases - deaths. PE recovered: From now on, recovered values will be calculated as total cases - active cases - deaths, based primarily on the data provided in the daily press releases. This value has been recalculated back to the date of the first reported deaths in PEI (2022-01-14). [UPDATE, 2022-01-31: As of today, it appears that PEI is now appropriately accounting for deaths in the recovered value posted to their dashboard.] NS is again reporting the number of doses administered (1st, 2nd, 3rd) on their dashboard, which will be used going forward. Some ON Public Health Unit (PHU) datasets have been retired and replaced with the Ontario Ministry of Health dataset, rewriting their cases, mortality and recovered datasets back to 2020-04-01. You can track this here: #97 NU cumulative testing number has been replaced by the time series of tests completed from the Public Health Agency of Canada (https://health-infobase.canada.ca/covid-19/epidemiological-summary-covid-19-cases.html). The reason for this is that the previously reported value, number of people tested, somehow decreased by ~80% and has not been corrected for several days. Since 2021-11-02, cases and recovered for PE have been based on the number of cases reported by PHAC on weekdays (https://health-infobase.canada.ca/covid-19/epidemiological-summary-covid-19-cases.html) and the daily press releases on weekends (https://www.princeedwardisland.ca/en/news), as the PHAC dataset is not updated over the weekend. This change is due to the very inconsistent updating of the usual data source, the PEI dashboard (https://www.princeedwardisland.ca/en/information/health-and-wellness/covid-19-testing-and-case-data). The data reported by PHAC seems to match the data reported in press releases. [Note that historical values for 2021-11-02 to 2021-12-20 were re-calculated on 2021-12-20. 2021-11-02 was selected because it was not too far back and there was agreement in the number of cumulative cases reported by PHAC and the province on this day (319).] [GitHub issue #89] Additional doses (booster doses, 3rd doses, 4th doses) doses are now being reported for most provinces in a new dataset: vaccine_additionaldoses_timeseries_prov / vaccine_additionaldoses_timeseries_canada.csv First doses may be calculated as: total doses administered – vaccine completion (2nd doses) – additional doses. README on GitHub has been updated to provide a better description of the dataset: https://github.com/ccodwg/Covid19Canada ON DATA NOTE: As of 2021-09-07, active cases for ON should be correctly reported. Note that this has resulted in a major discontinuity for recovered and active cases for ON on 2021-09-07. Our case and mortality data from ON have been sourced from individual PHU websites (rather than the provincial MOH dataset) since April 1, 2020. However, the recovered number continued to be sourced from the MOH. As the PHU and MOH datasets diverged (several thousand cases were never confirmed and thus not included in the MOH datasets), this resulted in an inflated active case count for the province (daily differences were more or less reliable). On 2021-09-07, we transitioned to using recovered numbers directly from the PHUs; thus, active cases should now be correctly reported for ON. Additionally, 13 cases were added to Haliburton Kawartha Pineridge (ON) on 2021-09-07 to maintain consistency with the corrected recovery calculation. We regret the inconvenience. DATA NOTE FOR SK: As of 2020-12-14, we are providing a daily version of the official SK dataset that is compatible with the rest of our dataset in the folder official_datasets/sk. See below for information about our regular updates. A REPLACEMENT DATASET IS IMMINENT. SK transitioned to reporting according to a new, expanded set of health regions on 2020-09-14. Unfortunately, the new health regions do not correspond exactly to the old health regions. Additionally, the provided case time series using the new boundaries do not exist for dates earlier than August 4, making providing a time series using the new boundaries impossible. For now, we are adding new cases according to the list of new cases given in the “highlights” section of the SK government website (https://dashboard.saskatchewan.ca/health-wellness/covid-19/cases). These new cases are roughly grouped according to the old boundaries. However, health region totals were redistributed when the new boundaries were instituted on 2020-09-14, so while our daily case numbers match the numbers given in this section, our cumulative totals do not. We have reached out to the SK government to determine how this issue can be resolved. We will rectify our SK health region time series as soon as it becomes possible to do so.

[Note that historical values for 2021-11-02 to 2021-12-20 were re-calculated on 2021-12-20. 2021-11-02 was selected because it was not too far back and there was agreement in the number of cumulative cases reported by PHAC and the province on this day (319).] [GitHub issue #89] Additional doses (booster doses, 3rd doses, 4th doses) doses are now being reported for most provinces in a new dataset: vaccine_additionaldoses_timeseries_prov / vaccine_additionaldoses_timeseries_canada.csv First doses may be calculated as: total doses administered – vaccine completion (2nd doses) – additional doses.

DATA NOTES: - IMPORTANT NOTICE: Due to recent changes in the availability of COVID-19 testing, case counts can no longer be considered a reliable indicator of spread. - SK data reporting will continue in the near future when we determine how to integrate the newly reported data format. - As of 2021-02-10, recovered & active case values should be discarded, as BC has stopped reporting these metrics. - See notice in “RECENT CHANGES” section below regarding NS cases since 2021-12-10. - See notice in “RECENT CHANGES” section below regarding PE cases since 2021-11-02.

PLEASE CONTACT US REGARDING ANY ERRORS YOU MAY FIND. https://opencovid.ca/contact-us/ NEWS RELEVANT TO COVID-19 DATA: Beginning 2022-02-07, Saskatchewan will only be reporting a limited set of data once per week on Thursdays. See the following for more details: https://www.saskatchewan.ca/government/news-and-media/2022/february/03/living-with-covid-transition-of-public-health-management RECENT CHANGES TO THE DATASET: SK total doses number has been fixed retroactively to include third doses. Previously it included only first and second doses, unlike other provinces. Additionally, added historical NU third doses reported in the vaccine coverage file provided by PHAC (https://health-infobase.canada.ca/covid-19/vaccination-coverage). BC recovered: As of 2021-02-10, BC will no longer report the number of active or recovered cases. “February 10, 2022: Active Cases have been removed from the dashboard as the values no longer reflect active community transmission numbers.” PE recovered: From now on, recovered values will be calculated as total cases - active cases - deaths, based primarily on the data provided in the daily press releases. This value has been recalculated back to the date of the first reported deaths in PEI (2022-01-14). [UPDATE, 2022-01-31: As of today, it appears that PEI is now appropriately accounting for deaths in the recovered value posted to their dashboard.] NS is again reporting the number of doses administered (1st, 2nd, 3rd) on their dashboard, which will be used going forward. Some ON Public Health Unit (PHU) datasets have been retired and replaced with the Ontario Ministry of Health dataset, rewriting their cases, mortality and recovered datasets back to 2020-04-01. You can track this here: #97 NU cumulative testing number has been replaced by the time series of tests completed from the Public Health Agency of Canada (https://health-infobase.canada.ca/covid-19/epidemiological-summary-covid-19-cases.html). The reason for this is that the previously reported value, number of people tested, somehow decreased by ~80% and has not been corrected for several days. Since 2021-11-02, cases and recovered for PE have been based on the number of cases reported by PHAC on weekdays (https://health-infobase.canada.ca/covid-19/epidemiological-summary-covid-19-cases.html) and the daily press releases on weekends (https://www.princeedwardisland.ca/en/news), as the PHAC dataset is not updated over the weekend.

DATA NOTES: - IMPORTANT NOTICE: Before using our data, please read the updated “Data notes and caveats” section of the README: https://github.com/ccodwg/Covid19Canada#datasets - IMPORTANT NOTICE: Due to recent changes in the availability of COVID-19 testing, case counts can no longer be considered a reliable indicator of spread. - REPORTING OF RECOVERED/ACTIVE CASES: As of 2021-02-10, recovered & active case values should be discarded, as several provinces (BC, SK) have stopped reporting these metrics. - SK data have been added up to 2022-02-20, based on the weekly differences reported in the weekly epidemiology report. - See notice in “RECENT CHANGES” section below regarding NS cases since 2021-12-10. - See notice in “RECENT CHANGES” section below regarding PE cases since 2021-11-02.

PLEASE CONTACT US REGARDING ANY ERRORS YOU MAY FIND. https://opencovid.ca/contact-us/ NEWS RELEVANT TO COVID-19 DATA: RECENT CHANGES TO THE DATASET: Beginning 2022-02-07, Saskatchewan will only be reporting a limited set of data once per week on Thursdays. See the news release for more details (https://www.saskatchewan.ca/government/news-and-media/2022/february/03/living-with-covid-transition-of-public-health-management). Metrics will be updated as best as possible using weekly values reported in the weekly epi report. The Thursday reports report data up to the previous Sunday (actually, Saturday, but these data would have been reported on Sunday under the previous reporting model). The value for total doses and additional doses (3rd doses) is likely inflated since 2022-02-13 since 4th doses are no longer being excluded from the total doses and additional doses count, as they were prior to this date. Formulas used: total_administration = previous value + “total”; vaccine_completion = previous total + “second dose of two” + “Janssen single dose”; additional_doses = previous total + “first and second boosters after complete series”. Weekly values are used rather than cumulative values due to inconsistencies reported between cumulative values in this report and cumulative values previously reported on the dashboard. SK total doses number has been fixed retroactively to include third doses. Previously it included only first and second doses, unlike other provinces. Additionally, added historical NU third doses reported in the vaccine coverage file provided by PHAC (https://health-infobase.canada.ca/covid-19/vaccination-coverage). BC recovered: As of 2021-02-10, BC will no longer report the number of active or recovered cases. “February 10, 2022: Active Cases have been removed from the dashboard as the values no longer reflect active community transmission numbers.” PE recovered: From now on, recovered values will be calculated as total cases - active cases - deaths, based primarily on the data provided in the daily press releases. This value has been recalculated back to the date of the first reported deaths in PEI (2022-01-14). [UPDATE, 2022-01-31: As of today, it appears that PEI is now appropriately accounting for deaths in the recovered value posted to their dashboard.] NS is again reporting the number of doses administered (1st, 2nd, 3rd) on their dashboard, which will be used going forward. Some ON Public Health Unit (PHU) datasets have been retired and replaced with the Ontario Ministry of Health dataset, rewriting their cases, mortality and recovered datasets back to 2020-04-01. You can track this here: #97 NU cumulative testing number has been replaced by the time series of tests completed from the Public Health Agency of Canada (https://health-infobase.canada.ca/covid-19/epidemiological-summary-covid-19-cases.html). The reason for this is that the previously reported value, number of people tested, somehow decreased by ~80% and has not been corrected for several days. Since 2021-11-02, cases and recovered for PE have been based on the number of cases reported by PHAC on weekdays (https://health-infobase.canada.ca/covid-19/epidemiological-summary-covid-19-cases.html) and the daily press releases on weekends (https://www.princeedwardisland.ca/en/news), as the PHAC dataset is not updated over the weekend.

This change is due to the very inconsistent updating of the usual data source, the PEI dashboard (https://www.princeedwardisland.ca/en/information/health-and-wellness/covid-19-testing-and-case-data). The data reported by PHAC seems to match the data reported in press releases. [Note that historical values for 2021-11-02 to 2021-12-20 were re-calculated on 2021-12-20. 2021-11-02 was selected because it was not too far back and there was agreement in the number of cumulative cases reported by PHAC and the province on this day (319).] [GitHub issue #89] Additional doses (booster doses, 3rd doses, 4th doses) doses are now being reported for most provinces in a new dataset: vaccine_additionaldoses_timeseries_prov / vaccine_additionaldoses_timeseries_canada.csv First doses may be calculated as: total doses administered – vaccine completion (2nd doses) – additional doses.

DATA NOTES: - IMPORTANT NOTICE: Before using our data, please read the updated “Data notes and caveats” section of the README: https://github.com/ccodwg/Covid19Canada#datasets - IMPORTANT NOTICE: Due to recent changes in the availability of COVID-19 testing, case counts can no longer be considered a reliable indicator of spread. - REPORTING OF RECOVERED/ACTIVE CASES: As of 2021-02-10, recovered & active case values should be discarded, as several provinces (BC, SK) have stopped reporting these metrics. - Note that NT includes Rapid Antigen Tests (RAT) and Point of Care Tests (POCT) in their case numbers. However, they have ceased to report PCR testing numbers. This will be dealt with in the coming days. - See notice in “RECENT CHANGES” section below regarding NS cases since 2021-12-10. - See notice in “RECENT CHANGES” section below regarding PE cases since 2021-11-02.

PLEASE CONTACT US REGARDING ANY ERRORS YOU MAY FIND. https://opencovid.ca/contact-us/ NEWS RELEVANT TO COVID-19 DATA: NS data reporting news (2022-03-03; https://novascotia.ca/news/release/?id=20220303002): - There will be an increase in new lab-confirmed cases of COVID-19 reported because of a change in testing protocol announced last week. People with positive rapid test results are now able to get a confirmatory PCR lab test. - The last daily COVID-19 news release and data dashboard update will be on Friday, March 4, as Nova Scotia moves to weekly reporting. The next COVID-19 release and dashboard update will be on Thursday, March 10. RECENT CHANGES TO THE DATASET: Beginning 2022-02-07, Saskatchewan will only be reporting a limited set of data once per week on Thursdays. See the news release for more details (https://www.saskatchewan.ca/government/news-and-media/2022/february/03/living-with-covid-transition-of-public-health-management). Metrics will be updated as best as possible using weekly values reported in the weekly epi report. The Thursday reports report data up to the previous Sunday (actually, Saturday, but these data would have been reported on Sunday under the previous reporting model). The value for total doses and additional doses (3rd doses) is likely inflated since 2022-02-13 since 4th doses are no longer being excluded from the total doses and additional doses count, as they were prior to this date. Formulas used: total_administration = previous value + “total”; vaccine_completion = previous total + “second dose of two” + “Janssen single dose”; additional_doses = previous total + “first and second boosters after complete series”. Weekly values are used rather than cumulative values due to inconsistencies reported between cumulative values in this report and cumulative values previously reported on the dashboard. SK total doses number has been fixed retroactively to include third doses. Previously it included only first and second doses, unlike other provinces. Additionally, added historical NU third doses reported in the vaccine coverage file provided by PHAC (https://health-infobase.canada.ca/covid-19/vaccination-coverage). BC recovered: As of 2021-02-10, BC will no longer report the number of active or recovered cases. “February 10, 2022: Active Cases have been removed from the dashboard as the values no longer reflect active community transmission numbers.” PE recovered: From now on, recovered values will be calculated as total cases - active cases - deaths, based primarily on the data provided in the daily press releases. This value has been recalculated back to the date of the first reported deaths in PEI (2022-01-14). [UPDATE, 2022-01-31: As of today, it appears that PEI is now appropriately accounting for deaths in the recovered value posted to their dashboard.] NS is again reporting the number of doses administered (1st, 2nd, 3rd) on their dashboard, which will be used going forward. Some ON Public Health Unit (PHU) datasets have been retired and replaced with the Ontario Ministry of Health dataset, rewriting their cases, mortality and recovered datasets back to 2020-04-01. You can track this here: #97 NU cumulative testing number has been replaced by the time series of tests completed from the Public Health Agency of Canada (https://health-infobase.canada.ca/covid-19/epidemiological-summary-covid-19-cases.html).

PLEASE CONTACT US REGARDING ANY ERRORS YOU MAY FIND. https://opencovid.ca/contact-us/ NEWS RELEVANT TO COVID-19 DATA: AB: 2022-03-16: “Alberta has announced it will only report COVID-19 data on Wednesdays going forward.” https://edmonton.ctvnews.ca/alberta-to-report-covid-19-data-once-a-week-1.5821616 ON: On 2022-03-11, Ontario removed hundreds of COVID-19 deaths identified as “incidental”. https://www.cbc.ca/news/canada/toronto/covid19-ontario-march-11-1.6381330 RECENT CHANGES TO THE DATASET: Beginning 2022-02-07, Saskatchewan will only be reporting a limited set of data once per week on Thursdays. See the news release for more details (https://www.saskatchewan.ca/government/news-and-media/2022/february/03/living-with-covid-transition-of-public-health-management). Metrics will be updated as best as possible using weekly values reported in the weekly epi report. The Thursday reports report data up to the previous Sunday (actually, Saturday, but these data would have been reported on Sunday under the previous reporting model). The value for total doses and additional doses (3rd doses) is likely inflated since 2022-02-13 since 4th doses are no longer being excluded from the total doses and additional doses count, as they were prior to this date. Formulas used: total_administration = previous value + “total”; vaccine_completion = previous total + “second dose of two” + “Janssen single dose”; additional_doses = previous total + “first and second boosters after complete series”. Weekly values are used rather than cumulative values due to inconsistencies reported between cumulative values in this report and cumulative values previously reported on the dashboard. Some ON Public Health Unit (PHU) datasets have been retired and replaced with the Ontario Ministry of Health dataset, rewriting their cases, mortality and recovered datasets back to 2020-04-01. You can track this here: #97 Additional doses (booster doses, 3rd doses, 4th doses) doses are now being reported for most provinces in a new dataset: vaccine_additionaldoses_timeseries_prov / vaccine_additionaldoses_timeseries_canada.csv First doses may be calculated as: total doses administered – vaccine completion (2nd doses) – additional doses.

DATA NOTES: - IMPORTANT NOTICE: Our dataset will undergo significant changes on April 15, 2022. Please read our announcement here: https://raw.githubusercontent.com/ccodwg/Covid19Canada/master/ccodwg_dataset_announcement.pdf - IMPORTANT NOTICE: Before using our data, please read the updated “Data notes and caveats” section of the README: https://github.com/ccodwg/Covid19Canada#datasets - IMPORTANT NOTICE: Due to recent changes in the availability of COVID-19 testing, case counts can no longer be considered a reliable indicator of spread. - REPORTING OF RECOVERED/ACTIVE CASES: As of 2021-02-10, recovered & active case values should be discarded, as several provinces (BC, NS, SK) have stopped reporting these metrics. - Note that NT includes Rapid Antigen Tests (RAT) and Point of Care Tests (POCT) in their case numbers. However, they have ceased to report PCR testing numbers. This will be dealt with in the coming days. - Durham (ON) case, mortality, recovered time series has been replaced with the Ontario MoH dataset. See below for details. - MB has retired their COVID-19 dashboard and will be reporting once per week in their surveillance report: https://news.gov.mb.ca/news/?archive=&item=53998 / https://www.gov.mb.ca/health/publichealth/surveillance/covid-19/index.html - New MB data covers Sunday-Saturday and will be considered as being “reported” on Sunday according to the usual dating scheme - MB vaccination dose numbers are no longer being reported. - New case and recovered numbers for NL at the health region-level appear to be inaccurate (not shown on dashboard, but available via JSON query). Thus, recovered will be retired and cases will be reported at the province level only (i.e., all new cases will have not reported health regions). Added new cases from province-level total going back to 2022-03-12 (the day after the last HR-level case report). Death reporting appears unaffected. - MB is no longer reporting recovered/active case values. - AB is no longer reporting recovered/active case values. - NL appears to no longer be reporting third dose values or testing numbers. These values will be dealt with or retired in the coming days. - NS appears to no longer be reporting testing values. This will be dealt with in the coming days. - NS appears to no longer be reporting all vaccine values. This will be dealt with in the coming days. - See notice in “RECENT CHANGES” section below regarding NS cases since 2021-12-10. - See notice in “RECENT CHANGES” section below regarding PE cases since 2021-11-02.
