Spring 2024 COVID-19 Vaccine Recommendations

Individuals who are at increased risk of severe illness from COVID-19 may receive an additional dose of an XBB COVID-19 vaccine this Spring. Find out if you are eligible.

Individuals 6 months to 4 years of age who have not completed a COVID-19 vaccine series based on the vaccine product and immune status, should complete the series with an XBB mRNA COVID-19 vaccine.

All other individuals are not currently recommended to receive a COVID-19 vaccine dose in Spring 2024 and should wait until further Ministry recommendations. This includes individuals who are not at increased risk of severe illness from COVID-19 who did not receive an XBB COVID-19 vaccine in Fall 2023, unless they are specifically recommended to receive a dose by their health care provider.

 

Vaccine eligibility & doses

COVID-19 vaccines are safe and effective in preventing severe illness and death from the COVID-19 virus. If you have questions about whether the COVID-19 vaccine is right for you, speak to your health care provider or access information from reliable and trusted sources.

Individuals not previously vaccinated
  • Individuals not previously vaccinated who are:
    • 6 months to 4 years and are not known to be at high risk of severe illness due to COVID-19 may be vaccinated with a COVID-19 vaccine.
    • 5 years and older should be vaccinated with a COVID-19 vaccine.
  • The vaccine you will receive will depend on your age, medical history and the vaccine available. You will receive a Health Canada approved, age-appropriate vaccine.
  • Individuals who have not been previously vaccinated and are not considered moderately to severely immunocompromised and with no previous history of multisystem inflammatory syndrome in children and adults (MIS-C and MIS-A) are recommended to wait 8 weeks from their last known COVID-19 infection.
  • See recommendations for those who are moderately to severely immunocompromised.
Individuals previously vaccinated
  • The Ministry of Health is recommending that the following individuals may receive an additional dose of an XBB COVID-19 vaccine in Spring 2024, especially those who did not receive a dose during the Fall 2023 program. It is recommended to receive the additional dose if it has been 6 months from the previous COVID-19 vaccine dose or known COVID-19 infection (whichever is later):
    • Adults 65 years of age and older
    • Adult residents of long-term care homes and other congregate living settings for seniors
    • Individuals 6 months of age and older who are moderately to severely immunocompromised (due to an underlying condition or treatment)
    • Individuals 55 years and older who identify as First Nations, Inuit, or Metis and their non-Indigenous household members who are 55 years and older
  • All other individuals are not currently recommended to receive a COVID-19 vaccine dose in Spring 2024 and should wait until further Ministry recommendations. This includes individuals who are not at increased risk of severe illness from COVID-19, and those who did not receive an XBB COVID-19 vaccine in Fall 2023, unless they are specifically recommended to receive a dose by their health care provider.
  • Individuals 6 months to 4 years of age who have not completed an appropriate COVID-19 vaccine series (based on the vaccine product and immune status), should complete the series using the appropriate number of doses using an XBB mRNA COVID-19 vaccine. See Appendix B and Appendix D in the COVID-19 Vaccine Guidance for the appropriate schedule. (external PDF).
  • Evidence shows that waiting the recommended interval of 6 months or greater between infection and vaccination results in a better immune response and higher vaccine effectiveness.
  • A shorter interval (3 to less than 6 months) may be considered based on age and risk. Individuals are encouraged to speak with their health care provider.
  • See Appendix B and Appendix C in the COVID-19 Vaccine Guidance for the appropriate schedule based on immunization history and immune status for Spring 2024 (external PDF).
  • See recommendations for those who are moderately to severely immunocompromised.
Types of Vaccines
  • Health Canada has approved the following vaccines:
    • Moderna mRNA XBB (6 months and older)
    • Pfizer mRNA XBB (6 months and older)
    • Novavax XBB vaccine (12 years of age and older) who are not able or willing to receive an mRNA vaccine
  • All COVID-19 vaccines authorized in Canada are proven safe and effective.
  • The vaccine you will receive will depend on your age, medical and immunization history and the vaccine available. You will receive a Health Canada approved, age-appropriate vaccine.
  • Select pharmacies or health care providers may offer other Health Canada approved vaccines, such as Novavax.

Residents are encouraged to get their COVID-19 vaccines wherever they receive their influenza vaccine, such as at participating pharmacies or their primary care provider. The COVID-19 vaccination service for homebound residents is available to Halton residents who are unable to leave their homes. To be eligible for this service, the person must be unable to physically leave their home or leaving home requires a considerable effort. For example, the person normally does not leave their home on their own (with or without support) to access medical, public, or social services.

Eligible residents can submit a request for this service by completing the COVID-19 Vaccination Service for Homebound Residents – service form.

This form can be completed by a:

  • eligible Halton resident or substitute decision maker
  • physician or health care provider
  • congregate living administrator

This is not a rapid referral program.

Halton Region Public Health will contact applicants within two to four weeks of receiving an application.

Lack of access to transportation does not define an individual as homebound. There are a range of safe and reliable transportation options, including special transit services for older adults and people with disabilities.

For more information on transportation options available, please visit Transportation Options for Older Adults.

Children 6 months to under 12 years of age

Children 6 months to under 12 years of age can receive the COVID-19 vaccine at a pharmacy or primary care office. If the pharmacy or primary care office cannot provide the vaccine, please book an appointment with Halton Region COVID-19 Community Immunization Clinic.

 

Get additional information about vaccines

It’s okay to have questions about COVID-19 vaccines. Please make sure you are getting information and answers to your questions from your health care provider or other reliable and verified, scientific sources.

Experts like the Society of Obstetricians and Gynaecologists of Canada (SOGC) and National Advisory Committee on Immunization (NACI) strongly recommend those that are pregnant or breastfeeding to get a complete COVID-19 vaccine series. Talk to your health care provider if you have any questions about getting the COVID-19 vaccine. More information is also available from these trusted resources:

  • Individuals 6 months and older who are moderately to severely immunocompromised are recommended to:
    • receive an additional dose to complete the initial series,
    • receive at least one dose of the XBB COVID-19 vaccine this Spring 2024, and
    • wait 4 to 8 weeks from the previous COVID-19 vaccine dose or known COVID-19 infection (whichever is later).
  • The Moderna XBB vaccine may be more acceptable and more feasible due to fewer doses in the schedule for individuals 6 months to 4 years.
  • The vaccine you will receive will depend on your age, medical and immunization history and the vaccine available. You will receive a Health Canada approved, age-appropriate vaccine.
  • Get the latest information on COVID-19 vaccine doses and eligibility (external link).
 

Answers to frequently asked questions

  • Although COVID-19 symptoms in children can be mild, some develop more severe symptoms or require hospitalization, even without underlying health conditions.
  • Children can continue to have symptoms long after a COVID-19 infection has cleared.
  • Some children can develop other complications from COVID-19 beyond the infection itself, including a rare but serious condition called multisystem inflammatory syndrome (MIS-C).
  • COVID-19 infection can impact daily routines and can have an impact on children’s mental, social and emotional health.
  • Children who have underlying medical conditions are strongly recommended to stay up to date with their COVID-19 vaccinations.

For individuals six months of age and older, COVID-19 vaccines can be given at the same time or any time before or after another vaccine (for example, the annual flu vaccine, or other regularly scheduled vaccines).

There are two exceptions:

  • Arxevy for Respiratory Syncytial Virus (RSV): As a precaution, it is recommended to be administered at least 2 weeks before or after the administration of other vaccines, including the COVID-19 or influenza vaccines. See the ministry’s website on RSV (external link) for more information.
  • Imvamune for monkeypox (mpox): As a precaution, it is recommended to wait at least 4 weeks before or after administration of an Imvamune vaccine. However, the administration of Imvamune as pre- or post-exposure vaccination should not be delayed in an individual who has recently received a COVID-19 vaccine.
  • All COVID-19 vaccines authorized in Canada are proven to be safe, effective and of high quality.
  • The vaccines were tested in clinical trials for children. The clinical trials found the vaccine was safe for children, just as we know it is safe in adults and adolescents. The risk of serious side effects from the vaccines is very low. Children who have underlying medical conditions are strongly recommended to stay up to date with their COVID-19 vaccinations.
  • There are rare cases when the vaccine should not be given to children including children who:

Some children experience mild side effects such as red arm, tiredness, chills and muscle/joint pain. These side effects go away after a few days, and are similar to other routine childhood vaccinations. In children six months to two years of age, the most common side effects reported were irritability/crying, pain, sleepiness and loss of appetite. Serious side effects such as anaphylaxis or severe allergy are rare. Long term side effects are not expected from COVID-19 mRNA vaccines. mRNA vaccines have been studied in humans since 2013 with no known long-term effects.

 

Get your proof of vaccination, receipt & records

Individuals who received a COVID-19 vaccine not authorized by Health Canada* (for example, while in another country) are recommended to receive additional doses to stay up-to-date:

  • Individuals 6 months of age and older who received one or more non-Health Canada authorized COVID-19 vaccine(s) are recommended to receive one or more doses of a COVID-19 XBB vaccine, at least 6 months after the previous COVID-19 vaccine dose or confirmed COVID-19 infection (whichever is later).
  • The number of doses will depend on how many previous doses the individual received and their immune status.

Please bring your COVID-19 vaccination records with you to get your COVID-19 vaccine. The COVID-19 vaccination records must be in English, or you must have a certified translation into English. Vaccine receipts must include your name, date of vaccination, type of vaccine and dose. For information on how to include your out-of-province vaccinations in your Ontario vaccination certificate, please see Report an out-of-province COVID-19 vaccination below.

If you live in Halton and received a COVID-19 vaccine outside of Ontario or Canada, report this information to Halton Region Public Health. This information must be verified before you can access your vaccine certificate with a QR code. The information you submit will be assessed within three weeks and, if needed, you will receive further instructions by email.

How to get your next dose:

Visit a pharmacy, primary health care provider or other vaccination clinic – Before attending a pharmacy or primary care provider to get your COVID-19 vaccine, you must first report any out-of-province vaccination records for your primary series using the button below. After you receive confirmation that your records have been verified, you can get your COVID-19 vaccine at any participating pharmacy, primary care office or other vaccination clinic. Find locations offering the COVID-19 vaccine.

Report your out-of-province COVID-19 vaccination records

Businesses and organizations may voluntarily choose to check for proof of vaccination. Individuals may also be required to show proof of vaccination when travelling within and outside of Canada. For more information, visit Ontario.ca/proofofvaccination (external link).

Use the Provincial tool to find out how to get your enhanced vaccine certification (external link). You can save an electronic copy to your mobile phone or print a copy with your QR code.

If you received a COVID-19 vaccine outside of Ontario and need an enhanced vaccine certificate, you must first have your proof of vaccination verified by Halton Region Public Health. Learn about what type of vaccination records are accepted and report your out-of-province COVID-19 vaccination records to be verified.

If you don't have a health card (this does not include lost or stolen health cards), email accesshalton@halton.ca or call 311 to receive a COVID ID (identification will be verified). A COVID ID is a unique number assigned to you by your public health unit (in place of an Ontario health card number) that can be used to obtain a copy of your vaccine certificate. You can then call the Provincial Vaccine Contact Centre at 1-833-943-3900 and you will be emailed a secure link to access your vaccine certificate.

In general, there are few situations where someone meets the criteria for a medical exemption to COVID-19 vaccination. Most people can safely receive COVID-19 vaccines.

For information on how to receive proof of a medical exemption, visit the Ministry of Health’s Proof of COVID-19 vaccination (external link).

 

COVID-19 Data in Halton: Interactive Dashboard

Having trouble loading the dashboard? Open it in a new tab on your phone or tablet (external link) or on your computer (external link).

Data notes

Data sources

  • Halton case data: Public Health Case and Contact Management (CCM) Solution, extracted Thursday mornings to reflect cases reported by end of the previous day.
  • Halton test volume and percent positivity data: Ministry of Health, SAS Visual Analytics Tool, COVID-19 Testing reports (New as of April 6, 2022), extracted Thursday.
  • Halton hospital data: Ministry of Health, SAS Visual Analytics Tool, COVID Regional Hospital and Hospital Utilization reports, extracted Thursday.
  • Halton vaccination data: IntelliHealth, COVax package, extracted Thursday mornings to reflect immunizations administered by end of the previous day.
  • Vaccine coverage denominators: Institute for Clinical Evaluative Sciences, Applied Health Research Question #2021 0950 080 000.

General

  • Numbers should not be expected to match numbers reported by other sources, due to different data extraction times.
  • All data are dynamic and subject to change with future updates.
    • CCM and COVax are dynamic reporting systems that allow ongoing updates to data previously entered.
    • As a result, data extracted from CCM and COVax represent a snapshot at the time of extraction and may differ from previous or subsequent reports.
    • Data are updated Thursday. Numbers update dynamically within the dashboard by 4 p.m. on Thursday as server times allow.
    • Based on information gathered while doing case investigation, numbers may increase or decrease to reflect our most up to date information. Numbers may change significantly when data cleaning initiatives are completed.
  • All data except hospital occupancy/counts and data shown in the ”Halton Hospitals” tab includes only individuals whose main usual residence is in Halton Region. Cases who have municipality information pending are excluded.
  • As of January 1, 2022, probable cases are no longer included in total case counts due to changes in testing and case management necessitated by the Omicron surge. Prior to 2022, probable cases were individuals presumed to have COVID-19 because they had symptoms of COVID-19 and were travelers returning from an affected area, had close contact with a confirmed case, lived/worked in a facility experiencing a COVID-19 outbreak, had indeterminate test results, or had a preliminary positive result from a Health Canada approved point-of-care assay (rapid COVID-19 test).
  • The number of cases should not be considered exactly equivalent to the unique number of individuals in Halton who have been diagnosed with COVID-19, because there are some individuals who are counted twice because they are confirmed reinfection cases. A confirmed reinfection case is a person who has tested positive for COVID-19 more than once , with time-based or test-based clearance between the two infections.

Vaccinations

  • Data on the “Doses administered in Halton” subtab are representative of doses administered anywhere in Halton Region, including community and hospital-based clinics run by Halton Region Public Health, Halton Healthcare, Joseph Brant Hospital, or other partners on a pop-up basis; other clinic settings run by the Halton Region Health Department (which includes Halton Region Public Health and Halton Region Paramedic Services) and other partners; pharmacies; and physicians’ offices.
  • Data on the “Doses administered in Halton” subtab include primary series (first and second doses), and should therefore not be interpreted as the unique number of individuals vaccinated. These data include doses administered to non-Halton residents (e.g. staff who work at a Halton facility but live outside Halton), and do not include any doses Halton residents may have received outside Halton (e.g. Halton residents who work at facilities outside Halton and were vaccinated there).
  • Data on the “Doses administered in Halton” subtab reports doses administered by age at time of first dose and includes individuals without a known age at time of vaccination (pending data cleaning). Data on the “Vaccine coverage in Halton residents” subtab assigns residents to an age category based on age at time of data extraction from Intellihealth (Thursdays) and excludes individuals without a known age, as known age is required to calculate vaccine coverage. Children 0-6 months of age are included in denominators used to calculate coverage estimates. However, children 0-6 months of age are not eligible for COVID-19 vaccination, and therefore, are not included in the numerator.
  • Data on the “Vaccine coverage in Halton residents” subtab reflects Halton residents, rather than doses. It includes all Halton residents who have had at least a completed primary series of doses (one-dose and two-dose coverage). It also shows a subset of these individuals who have had at least one booster dose, separately shown according to whether the most recent booster dose was given in the last 6 months, or 6 or more months ago. It includes known Halton residents who were immunized in Halton, as well as Halton residents who received a primary series and/or a booster dose outside Halton, if the dose was recorded in COVax. A second dose is considered valid if it was not given earlier than the product monograph recommends for the specified vaccine product. A booster dose is considered valid if it was not given earlier than the minimum interval of 28 days from the second dose or any previous booster dose. Only residents alive on September 1, 2021 are included in coverage estimates.
  • Vaccine coverage is shown by completed primary series, booster doses given less than 6 months ago, and doses given 6 or more months ago.  The percentages of residents receiving a booster in these timeframes are subsets of the total percentage of residents who completed a primary series, since completing a primary series is a prerequisite to receiving a booster.
  • Vaccine coverage is calculated for the population aged 18 and up, 12 and up, 5 and up, and for the total population across all age groups (0+). Booster dose coverage is calculated for the population aged 5 and up. 
  • Vaccine coverage is calculated using September 2021 Halton Region population estimates provided by ICES based on the Registered Persons Database.
    • Population estimates reflect the postal codes associated with health cards, and therefore are subject to error.
  • For individuals aged less than 65 years of age, individuals who did not have any contact with the Ontario health care system in the last 9 years have been excluded and for individuals aged 65+, individuals who did not have any contact with the Ontario health care system in the last 3 years have been excluded. These individuals were excluded as they likely are not living in the province. Vaccine coverage by Forward Sortation Area (FSA) is available on the ICES COVID-19 Dashboard under the “Vaccine Coverage in Ontario” heading (external link). FSA is the first three characters of a postal code. The following FSAs are in Halton Region: L0P, L6H, L6J, L6K, L6L, L6M, L7G, L7J, L7L, L7M, L7N, L7P, L7R, L7S, L7T, L9E, L9T.
  • Data from COVax are subject to misclassification, as assignment to a health unit of residency is dependent on the postal code entered but can be overwritten, and new postal codes may not be correctly assigned by the system. Halton residents may be misclassified as non-Halton residents and therefore not included in the coverage estimates, and conversely, some non-Halton residents could be erroneously classified as Halton residents depending on the address provided or edits to the health unit field by the immunizer. This is especially true when Halton residents with a newer postal code are immunized outside Halton. Due to these concerns, wherever possible, health unit residency has been assigned outside the system on the basis of postal code and municipality entered into COVax using an updated postal code lookup maintained by Halton Region Public Health. Therefore, individuals with a Halton municipality or postal code in COVax but entered with a different client health unit are assumed to actually be Halton residents; and individuals without a Halton municipality or postal code but entered with a client health unit of Halton are assumed to actually be non-Halton residents. If health unit is missing in COVax, but the reason for immunization involves being a resident of a facility in Halton, the individual is assumed to be a Halton resident.

Snapshot

  • Virus Spread and Severity Indicators:
    • Hospitalizations and ICU admissions are subject to significant undercounting and delays, as capturing this information requires Public Health to be notified by an external party that the case has been hospitalized and admitted to ICU. Public Health is typically not notified when a Halton resident is hospitalized or in an ICU outside Halton.
    • The trend in wastewater signal may still be relatively high, but may not necessarily be increasing. There is lag time required to collect, process and analyze the samples which limits our ability to use these data to identify changes in community transmission as it occurs.
  • Health System Capacity Indicators:
    • ICU beds and cases are a subset of acute care beds and cases.
    • Individuals who are in the hospital who are no longer testing positive for COVID-19 but who previously tested positive will be counted in the occupancy rates, but not in the confirmed hospital case counts.
    • Individuals with COVID-19 who are in Joseph Brant’s Pandemic Response Unit will be included in the confirmed COVID-19 hospital case count, but not in the occupancy rate.
    • Individuals who visited the emergency room but who were not admitted to hospital are not included in the occupancy rates or case counts.
    • Individuals who are admitted to Halton hospitals may not be Halton residents, and conversely, Halton residents may be hospitalized in hospitals outside Halton. Therefore, the counts of COVID-19 patients in hospital/ICU may not always include the same individuals represented as cases elsewhere in the dashboard, which focuses on Halton residents only.
    • Hospital case counts should not be expected to match the data on cases who have ever been hospitalized in the “Trends over time” tab. The hospital case counts include recent data submitted by the hospitals about both Halton residents and non-Halton residents with COVID-19 in their care, whereas the data on the “Trends over time” tab specifically reflects Halton residents only, and depends on hospitalization data for Halton cases being provided to Public Health, which may occur with delay or not at all.
  • For more information on the monitoring indicators, please see the technical notes (PDF file).

Trends over time

  • Interpret trends from the most recent days with caution, as information-gathering and data entry is ongoing for recently reported cases.
  • Reported date is the date the case was reported to public health. This does not represent the day the case was first publicly reported in the dashboard, and there may be delays between when the case is reported to public health and when it appears in the dashboard (e.g., due to time required to receive confirmatory lab results, or receive a case referral from another health unit). Episode date is a field that is intended to approximate the symptom onset date for each case. It is calculated hierarchically, using the earliest date among symptom onset date; specimen collection date; or the date the case was reported to public health, as available.
  • After December 31, 2021, case counts no longer reflect the true number of COVID-19 infections in Halton Region as confirmatory testing is focused on high-risk settings and individuals only.
  • The number of confirmed Halton COVID-19 cases admitted to hospital over time is subject to significant undercounting and delays, as it requires Public Health to be notified by an external party that the case has been hospitalized. Public Health is typically not notified when a Halton resident is hospitalized outside Halton.
  • Deaths due to COVID-19 include any fatality where the cause of death is recorded as COVID-19 on the death certificate. Cases where COVID-19 did not contribute to their death include COVID-19 cases who were still symptomatic/infected with COVID-19 at the time of death but their death was not attributed to their infection. Deaths due to an unrelated cause, such as a motor vehicle accident, are typically excluded entirely. Type of death may be recorded as pending until more information is known as there is often a lag time between when Public Health is notified that a case has died and when the receive the official death certificate is received.

Outbreaks

  • Our main priority in outbreak management is prevention. Ensuring appropriate measures are being taken requires time, in addition to collecting information on the status of cases. Data on outbreaks may therefore take additional time to be entered and reflected in the dashboard. Out of consideration for those affected, institutional outbreaks will also not be posted until after notification of staff, residents, and families has been completed.
  • The name of the affected location is included only for institutional and school outbreaks. The name of the affected location is not shown for congregate living outbreaks for privacy reasons.
  • Outbreaks are declared when the appropriate provincial definition is met. Provincial definitions for outbreaks vary by type of outbreak.
  • Open outbreaks are outbreaks that have not yet been declared over by the time of the dashboard refresh. Closed outbreaks are outbreaks that have been declared over by the time of the dashboard refresh.
  • For information on the types of locations included in each outbreak category, please place your cursor over the question mark symbol on the outbreaks page.

Lab testing

  • Test volume and percent positivity data are updated Thursday to reflect the past seven days of complete data. Due to the time required for processing of specimens, reporting will be delayed by seven days to allow for the lag time between specimen collection and reporting of results.
  • The number of tests shown per day represents the number of tests conducted on that date, as well as the preceding six days (7-day rolling value). Using a seven-day rolling value helps smooth out variability that may be associated with testing patterns (For example, the number of tests conducted may fluctuate on weekends or holidays).
  • Percent positivity is calculated as the total number of positive tests over the 7-day period ending in the specified date, divided by the total numbers of tests conducted over that 7-day period.
  • Test volume and percent positivity data reflect only lab tests that have been assigned to Halton Region based on Forward Sortation Areas located within Halton. There are several considerations associated with these data:
    • The unit of analysis is the number of tests completed. Individuals may have more than one test conducted, and each test will be counted. The numbers should not be interpreted as the unique number of individuals tested or testing positive, but rather the unique number of total and positive tests .
    • The COVID-19 test results are captured in the Ontario Laboratories Information System (OLIS). The testing date represents the date of specimen collection. Unconsented test results are excluded.
    • The location of tested individuals was based upon the test recipient’s postal code (and corresponding health unit). New postal codes issued in the last year are excluded as the postal code file is only updated once per year. These address assignments can lead to misclassification of the health unit.

Wastewater

  • All six wastewater treatments plants in Halton Region are sampled three times a week.
  • Sampling, testing and analyses are completed in collaboration with the University of Toronto, the University of Guelph and the Ontario Ministry of the Environment, Conservation & Parks (MECP).
  • Data will be updated once per week. The update is dependent on the timing of sampling, testing and analysis in collaboration with project partners.
  • An increasing or decreasing signal in wastewater trend is defined as a +/- 10% change in the 7-day moving average that is significant at the 90% significance level.

Halton Hospitals

  • As of December 29, 2021 hospitals began reporting patients hospitalized for COVID-19 and those with COVID-19. Prior to this, the data represent any COVID-19 positive patient hospitalized in a Halton hospital, regardless of the reason for hospitalization.
    • Hospitalizations for COVID-19 include confirmed cases of COVID-19 who are admitted to the hospital and are actively being treated for their COVID-19 infection and its symptoms or have had their hospitalization prolonged due to their COVID-19 diagnosis.
    • Hospitalizations with COVID-19 include confirmed cases of COVID-19 who are admitted to the hospital for reasons other than COVID-19, but test positive upon admission or during their hospital stay.
  • Individuals with COVID-19 who are in Joseph Brant’s Pandemic Response Unit will be included in the counts.
  • Individuals who visited the emergency room but who were not admitted to hospital are not included.
  • Individuals who are admitted to Halton hospitals may not be Halton residents, and conversely, Halton residents may be hospitalized in hospitals outside Halton. Therefore, the counts of COVID-19 patients in hospital may not always include the same individuals represented as cases elsewhere in the dashboard, which focuses on Halton residents only.
  • Hospital case counts should not be expected to match the data the “Trends over time” tab. The hospital case counts include recent data submitted by the hospitals about both Halton residents and non-Halton residents with COVID-19 in their care, whereas the data on the “Trends over time” tab specifically reflects Halton residents only, and depends on hospitalization data for Halton cases being provided to Public Health, which may occur with delay or not at all.
