Key Messages:
- The virus that causes COVID-19 (SARS-CoV-2) is primarily transmitted via exhaled respiratory droplets and particles that are propelled into the air after an infected person coughs, sneezes, talks, or breathes.
- COVID-19 can cause illness ranging from a very mild, cold-like illness to severe infections. Presentations may be atypical, especially in older persons, children, and people living with a developmental disability.
- It is important to note that people with COVID-19 can be asymptomatic while infected and transmission can still occur when infected people are asymptomatic or prior to developing symptoms.
Introduction |
COVID-19 is a disease caused by the SARS-CoV-2 virus. It is highly contagious and spreads more easily among those who are not vaccinated and/or have not been previously infected. Vaccination can help prevent the development of severe illness, among those who are vaccinated. COVID-19 most often causes respiratory symptoms similar to a cold, the flu, or pneumonia. Most people with COVID-19 have mild symptoms, but some people become severely ill. Some people, including those with minor or no symptoms may develop Post-COVID Conditions – also known as “Long COVID.” |

Signs and symptoms |
COVID-19 can cause illness ranging from a very mild, cold-like illness to a severe infection. Presentations may be atypical, especially in older persons, children and people living with a developmental disability. People with COVID-19 can be asymptomatic while infected; transmission can still occur when people are asymptomatic or prior to developing symptoms. Refer to the Public Health Agency of Canada’s COVID-19 signs, symptoms and severity of disease: a clinician’s guide, for a full list of symptoms. With ongoing community spread, please consider COVID-19 as a potential diagnosis for all patients presenting with symptoms of acute respiratory infection, regardless of their travel or contact history. |
Diagnosis and laboratory testing |
Clinicians play a vital role in helping patients navigate current testing resources, supporting patients after testing or providing testing in their own clinical setting as long as IPAC measures are followed. Public Health Ontario (PHO) and the Ontario College of Family Physicians have resources on COVID-19 IPAC measures. TestingThe Ministry of Health provides testing guidance and eligibility criteria for PCR testing, including for specific settings and populations. Testing of Health Care Workers (HCW)Please refer to Ministry of Health’s Appendix 1: Case Definitions and Disease-Specific Information - Disease: Diseases caused by a novel coronavirus, including Coronavirus Disease 2019 for testing and isolation expectations, setting specific guidance, or refer to guidance from your employer, if applicable. Serology testing for COVID-19There are limited clinical scenarios for which serology testing may be appropriate for diagnostic purposes, such as when assessing symptoms compatible with Multisystem Inflammatory Syndrome in Children (MIS-C). For additional information, please refer to: Public Health Ontario Coronavirus Disease 2019 – Serology. To date no studies have identified an immune marker that represents an absolute correlate of protection against SARS-CoV-2-infection (i.e., prevents an infection at a certain threshold), so serology is not useful in determining someone’s protection against future infection. Rapid Antigen Testing:
Management of staff returning to work in highest risk settings:
Asymptomatic testing
Testing for COVID-19 in your officeThere are additional resources to support seeing symptomatic patients in clinic, including offering testing, Ottawa Public Health’s IPAC resources and information and from Public Health Ontario, Ontario Health and from the Ontario College of Family Physicians. COVID-19 testing must comply with provincial eligibility criteria in all settings. Note that if you are collecting specimens that are part of a COVID-19 outbreak in a facility (e.g., long-term care or retirement home), please ensure that the outbreak number is included on the requisition, as per the PHO Respiratory Outbreak Testing Prioritization Protocol (PDF). ResultsIt is the responsibility of the ordering physician or health care professional to communicate test results to their patients. Patients can check their COVID-19 PCR test result the following ways if they have a valid Ontario photo health card:
For information on isolation and supports for people who are tested for COVID-19, please see the Management section. COVID-19 Testing and Assessment CentresMany local assessment centres have now closed. PCR testing and access to antiviral therapy is available through many local pharmacies, visit the province's website for more information. Details on how to access COVID-19 testing are also available on OPH’s testing page. Self-isolation for Individuals with symptoms of respiratory illness or testing positive for COVID-19:

Management |
Notification and management of high-risk contactsIndividuals should inform others of their exposure. Individuals who test positive or who have symptoms of COVID-19 should notify their household members and similar close contacts that they are ill and refer them to the OPH Isolation Instructions for COVID-19 webpage. A close contact is anyone an individual was less than two metres away from for at least 15 minutes, or multiple shorter lengths of time, without measures such as masking, distancing, and/or the use of personal protective equipment in the 48 hours before symptoms began or a positive test result, whichever came first. For more information please see guidance from the Ministry of Health Pharmaceutical TherapiesPlease note that OPH does not coordinate access to pharmaceutical treatments for individuals with COVID-19. Provincially, pharmacotherapies are coordinated through Ontario Health. The Ministry of Health provides information for patients on testing and antiviral eligibility and access. The Ministry of Health provides information for patients on testing and antiviral eligibility and access. Ontario Health provides recommendation on the use of Paxlovid. Additional resources:

Immunization | |||||||||||||||||||||||||||||||||||||||
Vaccine informationWhich vaccines are approved in Canada? Please see the Government of Canada’s list of approved vaccines authorized for use in Canada. Who can receive the vaccineAll residents are encouraged to receive their COVID-19 vaccinations. Getting the vaccine is the best way to protect yourself from becoming very sick and requiring hospitalization. As of July 7th, 2023, people five years and older seeking a booster for COVID-19 vaccination, are recommended to delay vaccination until the Fall. Delay until the fall so protection against COVID-19 is maximized during peak respiratory virus season. Find more information on who can receive the COVID-19 vaccine below.
Where to get vaccinatedOttawa Public Health offers COVID-19 vaccination through local community clinics and neighbourhood health and wellness hubs. Please note that masks are required at all Ottawa Public Health vaccination clinics. Find below, more information about each type of Ottawa Public Health clinic.
Other places in Ottawa offer COVID-19 vaccination such as select pharmacies, First Nations, Inuit and Métis clinics, the Kids Come First Health Team vaccination clinics, and Switch Health clinics. Find below, more information about other places that offer COVID-19 vaccination.
Supporting your patients to get vaccinatedFor more information on vaccine clinics in Ottawa, including where your patients can get vaccinated, patients can visit our public COVID-19 Vaccine webpage.Resources for patient counselling for the COVID-19 vaccines are available from the Centre of Effective Practice. Additionally, The Public Health Agency of Canada (PHAC) has developed a resource titled the COVID-19 Vaccination Tool Kit for Health Care Providers. This toolkit provides health care professionals with evidence-informed resources to support informed choices and constructive dialogue with patients about COVID-19 vaccines authorized for use in Canada. Even if your patient decides not to receive the COVID-19 vaccine, please continue to recommend they stay up to date with other vaccinations, including vaccination against influenza. Medical Exemptions from VaccinationThe Ontario Ministry of Health and Long-Term Care has provided guidance to assist health care professionals to determine if their patient has a contraindication to COVID-19 vaccination that qualifies for a medical exemption. See Table 1 in the linked Ministry of Health guidance document (PDF).
As per provincial guidance, in many instances, safe administration of subsequent doses of COVID-19 vaccine is possible under the management of an appropriate physician or nurse practitioner. True medical exemptions are expected to be infrequent and should be supported by expert consultation. Health care professionals can access the medical exemption form here: Statement of Medical Exemption – COVID-19 Vaccine Immunization form (PDF) Contraindications to VaccinationIf a patient has a history of severe immediate allergic reaction (e.g., anaphylaxis) to the vaccine or any of the vaccine ingredients, health care practitioners are encouraged to refer patients to an allergist prior to administration of COVID-19 vaccine.People who experienced a severe immediate allergic reaction after a dose of an mRNA COVID-19 vaccine can safely receive future doses of the same or another mRNA COVID-19 vaccine after consulting with an allergist/immunologist or another appropriate physician. For more information, please consult the Ontario Ministry of Health’s COVID-19 Vaccine Guidance. Vaccination Report an Adverse Event Following ImmunizationUnder the Health Protection and Promotion Act of Ontario, all healthcare professionals are required to report Adverse Events Following Immunization (AEFIs) to local public health units. If you see a patient with symptoms that could possibly be related to a recent vaccination, you as the healthcare professional are required to report the AEFI. Submitting a report doesn’t mean that the vaccine caused the event, but this is a critical component of monitoring the safety of all vaccines.In addition to AEFIs, health care professionals are asked to report Adverse Events of Special Interest (PDF) for COVID-19 vaccine safety surveillance. AEFIs and AESIs are reportable to the health unit of the patient’s residence. The reporting form (PDF) can be submitted by fax to OPH at 613-580-9660 or through our online form. If you are unsure, please be proactive and report. Become a Vaccine ProviderPrimary care providers in Ottawa are invited to administer COVID-19 vaccines in their offices. Please contact COVID Vaccine Partners at covidvaccinepartners@ottawa.ca for more information. To order Pfizer-BioNTech and Moderna COVID-19 vaccines, complete the Ottawa Public Health COVID-19 vaccine order form.Physician Billing The Ontario Medical Association has outlined information pertaining to billing for COVID-19 vaccination (PDF). The Ministry of Health and Long-Term Care also publishes OHIP bulletins to update on billing concerns, which include COVID-19. Physicians can also check the OMA portal for updates. Questions regarding submission of billing codes can be be directed to the Ministry of Health and Long-Term. Care’s Service Support Contact Centre at SSContactCentre.MOH@ontario.ca.

Prevention |
Infection prevention and control (IPAC) measures protect healthcare professionals, staff, and patients from the spread of disease, including COVID-19. A risk assessment of your clinic and exam rooms prior to any interaction with patients will help to determine which IPAC measures are needed, depending on the specific setting and procedures being performed. The resources below may assist as you implement appropriate IPAC measures within your practice. Public Health Ontario: IPAC Recommendations for use of Personal Protective Equipment for Care of Individuals with Suspect or Confirmed COVID-19 (PDF).
Recommendations in the guidance include:
Preparing your officeThe Hierarchy of Controls is an occupational health and safety framework for controlling hazards in the environment. The controls at the top of the hierarchy inverted triangle are the most effective measures, with personal protective equipment (PPE) being the least effective measure of control. All the levels of the framework are important, as they create many layers of protection. This framework can help to structure the approach to COVID-19 IPAC in a clinical setting: Elimination and substitutionThis layer of IPAC protection prevents people with COVID-19 from coming into the setting without knowledge of the health care professional, through active and passive screening.
Engineering controlsCOVID-19 can be spread by people with asymptomatic infections. Ventilation, physical barriers, and re-designed work areas to facilitate physical distancing can help decrease the risk of COVID-19 spreading from an infectious person.
Administrative controlsAdministrative controls include IPAC policies and procedures, healthy workplace policies, education and training, as well as signage.
