Updated: Public health management of cases and contacts associated with coronavirus disease 2019 (COVID-19)

Updated July 13, 2020

Note

This page is continually under review and will be updated as this situation evolves. Please visit the provincial and territorial resources for COVID-19 page for updated guidance specific to your province or territory.

On this page

The Public Health Agency of Canada (PHAC), in collaboration with Canadian public health experts has developed this guidance for federal/provincial/territorial (F/P/T) public health authorities (PHA) to support the management of cases and contacts of coronavirus disease 2019 (COVID-19) within their jurisdictions.

The strategy outlined in this guidance is intended to focus on case and contact management, in order to mitigate the health impacts of COVID-19 on Canadians. This guidance is based on the Canadian context and public health assumptions that reflect the currently available scientific evidence and expert opinion. The timing and intensity of virus activity has varied across Canada and within provinces and territories, i.e., some regions have had many cases and are experiencing local community transmission, while others continue to have isolated cases with limited person to person transmission. Consequently, the focus and intensity of public health actions may vary among jurisdictions as they each manage the situation they are experiencing at a given time. This guidance is subject to change as new information on transmissibility and epidemiology becomes available. It should be read in conjunction with relevant P/T and local legislation, regulations and policies. For information regarding COVID-19, refer to outbreak updates.

Case management - Confirmed, Probable and Suspect cases (with and without COVID-19 symptoms)

Reporting and Notification

The interim national case definitionReference 1 for COVID-19 has been updated, specifically for confirmed, probable and suspect cases, as well as associated surveillance reporting requirements. P/T public health authorities (PHA) should report confirmed and probable cases of COVID-19 nationally to the PHAC within 24 hours of receipt of their own notification.

It is important for front line health care providers to notify PHAs of any cases (i.e. confirmed, probable or suspect), and individuals who have symptoms compatible with COVID-19, but do not meet the currently identified exposure criteria for infection, in accordance with jurisdictional reporting requirements. PHAs will need to provide overall coordination with health care providers and provincial laboratories for the management of cases and to establish communication links with all involved health care providers for the full duration of illness.

Laboratory Testing

Facilitate appropriate laboratory testing by the health care provider at a community, hospital or reference laboratory (i.e., the National Microbiology Laboratory or a provincial public health laboratory (PHL) running a validated assay). This consists of detection of at least one specific gene target by a NAAT assay (e.g. real-time PCR or nucleic acid sequencing). Specimens being sent for testing should include information on exposure/travel history. Refer to national Protocol for Microbiological Investigations of Severe Acute Respiratory Infections (SARI)Reference 2 for details on specimen collection and handling, and for information on how to consult with the PHL microbiologist on-call. Refer also to additional laboratory guidance provided by PHLs.

Clinical Management/Treatment

The treating health care provider will provide clinical management of the case (whether in the home or in an acute care setting) based on their condition and at the discretion of the health care provider. At this time, there is no specific pharmaceutical treatment (e.g. antivirals) for cases of COVID-19. Canadian guidance on the clinical management of patients with moderate to severe COVID-19 is available.Reference 3

Health care workers providing care for a case should follow relevant guidance developed for infection prevention and control including Routine Practices and Additional PrecautionsReference 4, and COVID-19-specific infection prevention and control (IPC) guidanceReference 5. Any aerosol-generating medical procedures (AGMP), such as nebulized medications, should be avoided in the home environment. If an AGMP is required, consideration should be given to transferring the case to hospital due to the need for Additional Precautions.

Case Management in the Home and Co-Living Settings (isolation)

Epidemiologic evidence suggests that the majority of people who develop COVID-19 have mild illness and may not require care in a hospital. It is important that people who do not require hospital-level care convalesce in a suitable environment where effective isolation and appropriate monitoring (i.e. for worsening of illness) can be provided.

Symptomatic and asymptomatic cases should be isolated in the home setting (i.e. not go out unless directed to do so to seek medical care, do not take public transportation to seek medical care and avoid contact with others including those in your previous bubble). If transferring a case from the community to an acute care facility, notify the receiving facility prior to arrival to ensure appropriate IPC measures are in place.

For cases with symptoms: Home isolation should continue for a minimum of 10 days from the onset of symptoms or as directed by the PHA. The criteria for discontinuing home isolation includes: at least 10 days or up to 14 days, depending on the situation and PHA direction, have passed since onset of first symptom or laboratory confirmation of an asymptomatic case, the case did not require hospitalization, the case is afebrile and has improved clinically. Absence of cough is not required for those known to have chronic cough or for those who are experiencing reactive airways post infection.

For asymptomatic cases: The criteria for discontinuing home isolation includes: at least 10 days or up to 14 days, depending on the jurisdiction, have passed since laboratory confirmation OR, if symptoms develop, at least 10 days or up to 14 days, depending on the jurisdiction, after the onset date of symptoms.

The location where a person will be isolated will be determined by their healthcare provider and the PHA. Symptomatic people entering Canada are subject to legal orders for mandatory isolation and are not permitted to isolate in a place where they will have contact with vulnerable people. The Public Health Agency of Canada's Chief Public Health Officer will designate a facility for travelers who do not have an appropriate place to isolate.

When determining the suitability of an isolation location, there are several factors for PHAs to consider:

Psychosocial Considerations

PHAs should encourage individuals, families and communities to create a supportive environment for people who are isolating to minimize stress and hardship associated with isolation as the financial, social, and psychological impact can be substantial. Obtaining and maintaining public trust are key to successful implementation of these measures; clear messages about the criteria and justification for and the role and duration of isolation and ways in which persons will be supported during the isolation period will help generate public trust. Additional information on the psychological impacts of COVID-19 is available.

Public Health Monitoring of Cases:

Contact management (of probable and confirmed cases)

In an effort to help prevent or reduce the spread of COVID-19 in Canada, the entire population has been asked to:

Close contacts of confirmed and probable casesFootnote a occurring in Canada should be identified and managed as per the recommendations in this document to the extent possible. It is recognized that the level and intensity of public health actions may vary among jurisdictions as they each manage the situation they are experiencing at a given time. For suspect cases, most PHAs have self-assessment tools for individuals who are not being tested and information on how symptomatic suspect cases should inform their contacts.

Contact tracing effortsFootnote b should consider all individuals with whom a case had contact with while potentially infectious. Given that both pre-symptomatic and asymptomatic transmission can occur, contact tracing should include:

An individual risk assessment conducted by the PHA will identify each contact's exposure risk level and determine the required level and parameters of quarantine (self-isolation), and PHA actions for the 14-day monitoring period.

The purpose of contact management is twofold:

  1. to facilitate rapid identification of new cases and to reduce community spread by:
    • identifying and isolating any symptomatic contacts as quickly as possible; and
    • reducing the opportunity for transmission to others in the community from those without symptoms or with mild symptoms that may go unnoticed, and by providing contacts with information regarding infection prevention and control measures they should follow, what to do if they develop symptoms.
  2. to gain a better understanding of the epidemiology of this coronavirus.

Depending on exposure risk level, there are three categories of contacts (high, medium or low).

A contact who develops symptoms compatible with COVID-19 within the monitoring period should be managed as a suspect case.

Table 1 Categories of contacts by exposure risk level describes the risk level, provides isolation and contact management advice as well as associated PHA actionsFootnote c:

Table 1. Categories of contacts by exposure risk level
Risk Level Description of Risk LevelFootnote d Isolation Level/ Contact actions Public health authority (PHA) actions
High Close contact(s) of a case:
  • provided direct care for the case (including health care workers, family members or other caregivers), or who had other similar close physical contact (e.g. intimate partner) without consistent and appropriate use of recommended personal protective equipment Footnote eOR
  • who lived with or otherwise had close, prolongedFootnote fcontact (within 2 metres) with a case up to 48 hours prior to symptom onset or while the case was symptomatic and not isolating, OR
  • had direct contact with infectious body fluids of a case (e.g., was coughed or sneezed on) without the appropriate use of recommended personal protective equipment.Footnote e
  1. Quarantine (self-isolate)Footnote g at home for 14 days from last unprotected exposure
  2. Follow good respiratory etiquette and hand hygiene practices.
  3. Self-monitor for the appearance of symptoms, particularly fever and respiratory symptoms such as coughing or shortness of breath.
  4. Take and record temperature daily and avoid the use of fever reducing medications (e.g., acetaminophen, ibuprofen) as much as possible. These medications could mask an early symptom of COVID-19; if these medications must be taken, advise the PHA.
  5. Isolate within the home setting as quickly as possible should symptoms develop, and contact the local public health authority for further direction, which will include:
    • where to go for care,
    • appropriate mode of transportation to use, and
    • IPC precautions to be followed.
  • Conduct an individual risk assessment
  • Active daily monitoring of contacts for symptoms
Medium Non-close contact:
  • provided direct care for the case, (including health care workers, family members or other caregivers) or who had other similar close physical contact with consistent and appropriate use of personal protective equipment Footnote e OR
  • who lived or otherwise had prolonged Footnote fcontact but was not within 2 metres of a case up to 48 hours prior to symptom onset or while the case was symptomatic and not isolating.
Self-monitor for symptoms for 14 days following their last contact.

Follow actions recommended for the entire population

Avoid close contact with individuals at higher risk for severe illness

  • Conduct a risk assessment for non-close contacts, if feasible
  • No active monitoring
Low/No known risk Only transient interactions (e.g., walking by the case or being briefly in the same room) or unknown but possible transient interaction due to the occurrence of local community transmission.
  • Provide community level information
  • Provide individual advice, if required

Persons possibly exposed through travel

As of March 25, 2020, all travellers incoming to Canada are subject to mandatory quarantine (self-isolation) enforceable through an emergency order under the Quarantine Act: Minimizing the Risk of Exposure to COVID-19 in Canada - Order (Mandatory Isolation). Therefore, all incoming travellers are required to quarantine (self-isolate) at home (or another designated location) for 14 days following their arrival to Canada and:

Exemptions from quarantine (self-isolation) due to travel outside of Canada have been made for certain individuals who provide essential services as long as they are asymptomatic. Included are individuals who cross the border regularly to ensure the continued flow of goods and essential services, or those who provide other essential services to Canadians. These workers should:

Any traveller who develops symptoms compatible with COVID-19 within the 14-day mandatory quarantine (self-isolation) period should be considered and managed as a suspect case.

Contact tracing for airplane passengers and flight crew

Decisions related to contact tracing individual air travellers/crew who may have been exposed to a confirmed case of COVID-19 on a flight should be made based on a risk assessment conducted by the PHA to which the case is notified, considering the:

There is no direct evidence at present that contacting individual air travellers has facilitated early case finding. Nor is there evidence regarding transmission risk in relation to flight duration.

Should the PHA determine that contact tracing individual air travellers is warranted, the Public Health Agency of Canada's Office of Border and Travel Health can assist PHA in obtaining a flight manifest; however, it should be noted that flight manifests are not kept indefinitely and do not contain contact information on all travellers. PHA may be required to provide a letter citing their authorities under their Public Health Acts in order to obtain the manifest. If contact tracing is not feasible, a public advisory to notify the public of the potential exposure may be considered.

Contact tracing efforts should focus on those seated within a 2-metre radius of the case, as this is the accepted exposure risk area for droplet transmission.

Contact tracing efforts oriented towards individual air travellers/crew should, at a minimum, focus on:

PHAs may wish to request the aircraft seat map from airlines to best target the contact tracing efforts. If the seat map is not available, PHAs may wish to trace economy class passengers seated in the 5 seats surrounding the case in all directions, up to and including 3 rows in front and 3 rows behind the case. In business class, due to seat spacing this may only involve tracing passengers in the 2 surrounding rows due to the space between seats. PHAs may also wish to confirm that the case sat in the assigned seat for the duration of the flight, and ask about the case's movements during the flight.

PHAs could consider expanding the scope of their contact tracing for individual travellers if the case had severe symptoms, such as persistent coughing and sneezing, or had diarrhea or vomiting, during the flight. Alternatively, the PHA could consider publicly communicating the flight number and possibly the section of the plane where the case was seated, as long as it does not reveal the identity of the case. In the event that a crew member is a confirmed case of COVID-19 and was symptomatic during the flight, passengers seated in the area served by that crew member, as well as the other crew members, should be included in any individually-oriented contact tracing efforts.

Appendix 1: Instructions for isolating a case in the home or co-living setting

Isolating in the home setting

Stay at home

Individuals who need to isolate themselves include:

The case (confirmed, probable or suspect) should isolate themselves in the home setting for a minimum of 10 days or up to 14 days from the onset of symptoms as directed by the PHA. The criteria for discontinuing home isolation includes: at least 10 days or up to 14 days, as directed by the PHA, have passed since first symptom onset or laboratory confirmation of an asymptomatic case, the case did not require hospitalization, the case is afebrile and has improved clinically.

For asymptomatic cases: A case that is confirmed positive, but without symptoms, should isolate in the home  setting for a minimum of 10 days or up to 14 days, as directed by the PHA, from the date of the positive test.  If symptoms appear, the individual should isolate for 10 days or up to 14 days from the onset of symptoms,  as directed by the PHA.

Staying at home means:

Personal Protective Measures for infection prevention and control

The case should follow good respiratory etiquette and hand hygiene practices.

Respiratory etiquette

Respiratory etiquette describes a combination of measures intended to minimize the dispersion of respiratory droplets when coughing, sneezing and talking.

  • Cover coughs and sneezes with a medical mask, or if not available, a non-medical mask or face covering (i.e., constructed to completely cover the nose and mouth without gaping, and secured to the head by ties or ear loops) or tissue. Dispose of tissues in a lined waste container and perform hand hygiene immediately after a cough or sneeze OR
  • Cough/sneeze into the bend of your arm, not your hand

Hand hygiene

Hand hygiene refers to hand washing or hand sanitizing and actions taken to maintain healthy hands and fingernails. It should be performed frequently with soap and water for at least 20 seconds:

  • Before and after preparing food;
  • Before and after eating;
  • After using the toilet;
  • Before and after using a mask
  • After disposing of waste or handling contaminated laundry;
  • Whenever hands look dirty.

Handwashing with plain soap and water is the preferred method of hand hygiene, since the mechanical action is effective at removing visible soil and microbes.

If soap and water are not available, hands can be cleaned with an alcohol-based hand sanitizer (ABHS) that contains at least 60% alcohol, ensuring that all surfaces of the hands are covered (e.g. front and back of hands as well as between fingers) and rub them together until they feel dry. For visibly soiled hands, remove soiling with a wipe first, followed by use of ABHS.

When drying hands, disposable paper towels are preferred, but a dedicated reusable towel may be used and replaced when it becomes wet.

Avoid touching their eyes, nose, and mouth with unwashed hands.

Monitor your symptoms

The case should monitor their symptoms and immediately report worsening of symptoms to a health care provider or PHA for further assessment. If it is determined that transfer to an acute care facility is required, instructions will be provided regarding transportation (e.g. by ambulance or private vehicle). If calling an ambulance, the dispatcher should be notified that the case might have COVID-19. If the person is transferred by private vehicle, the receiving facility should be notified to ensure that appropriate infection prevention and control measures are in place. During travel, the ill person should wear a medical mask, or if not available, a non-medical mask or face covering (i.e., constructed to completely cover the nose and mouth without gaping, and secured to the head by ties or ear loops), if tolerable, or cover their nose and mouth with a tissue. Those transporting the ill person should use appropriate personal protective equipment when within 2 metres of the ill person (details below).

Limit contact with other people

The case should avoid being in close proximity (within 2 metres) of other people, including household members and visitors who do not have an essential need to be in the home, with the exception of individuals providing care or delivering supplies or food.

When interactions within 2 metres are unavoidable, these should be as brief as possible, and the case should wear a medical mask, or if not available, a non-medical mask or face covering (i.e., constructed to completely cover the nose and mouth without gaping, and secured to the head by ties or ear loops). If possible, the ill person or caregiver should arrange to have supplies dropped off at their front door to minimize direct contact. If the case must leave the home setting, a mask should be worn.

Masks

Medical masks provide a physical barrier that helps prevent the transmission of the virus from an ill person to a well person by blocking large particle respiratory droplets propelled by coughing, sneezing and talking. However, using a mask alone is not enough to stop transmission and must be combined with other prevention measures including physical distancing, respiratory etiquette and hand hygiene.

The following steps will help to ensure masks are used effectively:

  • Medical masks are recommended for cases of COVID-19 and for any household member providing direct care to a case; the coloured side of the mask should be worn facing out.
  • N95 respirators must be reserved for healthcare workers and should not be used for by a case or household caregivers.
  • If medical masks are not available for home use, non-medical mask or face covering (i.e., constructed to completely cover the nose and mouth without gaping, and secured to the head by ties or ear loops) worn by the ill person, if tolerable, to cover their mouth and nose may prevent respiratory droplets from contaminating others or landing on surfaces. These non-medical masks may also be worn by any household member providing care to a case.
  • Before putting on a mask, wash hands with soap and water or ABHS.
  • Cover mouth and nose with mask and make sure there are no gaps between your face and the mask, press the mask tight to your face using your fingers to secure along the perimeter of the mask, pressing firmly over the bridge of your nose. After putting on a new mask, wash hands again with soap and water or ABHS.
  • Avoid touching the mask while using it; if you do, clean your hands with soap and water or alcohol-based hand sanitizer.
  • Replace the mask with a new one as soon as it is damp or dirty with secretions. Do not re-use single-use masks.
  • Non-medical masks should be carefully removed and replaced when soiled or damp and laundered in hot water and then dried thoroughly.
  • To remove the mask, remove both straps from behind the ears or untie from behind head. Do not touch the front of mask, and ensure that the front of the mask does not touch your skin or any surfaces before you discard it in a waste container or place it in a hamper for laundering Wash hands with soap and water or ABHS.

Limit contact with pets and other animals

Due to the theoretical possibility that animals in the home could be infected by COVID-19 or transfer the virus from one person to another on their fur, as a precautionary measure, it is recommended that the case also refrain with contact with pets. If this is not possible, practice good hand hygiene before and after touching animals, and their food/supplies, as well as good respiratory etiquette.

Avoid Sharing Personal Household Items

The case should not share personal items with others, such as toothbrushes, towels, washcloths, bed linen, cigarettes, unwashed eating utensils, drinks, phones, computers, or other electronic devices.

Clean all high-touch surfaces

Disinfectants can kill the virus making it no longer possible to infect people. High-touch areas such as toilets, bedside tables and door handles should be disinfected daily using approved hard-surface disinfectants that have a Drug Identification Number (DIN). A DIN is an 8-digit number given by Health Canada that confirms the disinfectant product is approved and safe for use in Canada. When approved hard surface disinfectants are not available, for household disinfection, a diluted bleach solution can be prepared in accordance with the instructions on the label, or in a ratio of 5 millilitres (mL) of bleach per 250 mL of water OR 20 mL of bleach per litre of water. This ratio is based on bleach containing 5 % sodium hypochlorite, to give a 0.1 % sodium hypochlorite solution. Follow instructions for proper handling of household (chlorine) bleach. If they can withstand the use of liquids for disinfection, high-touch electronics such as phones, computers and other devices may be disinfected with 70% alcohol (e.g. alcohol prep wipes).Reference 7

Disposable gloves should be used when cleaning or handling surfaces, clothing, or linen soiled with body fluids. Dormitories and co-living settings where ill persons are convalescing should be cleaned and disinfected daily.

All used disposable contaminated items should be placed in a lined container before disposing of them with other household waste.

Self-care while convalescing

Treatment

At this time, there is no specific pharmaceutical treatment for COVID-19. The case should rest, eat nutritious food, stay hydrated with fluids like water, and manage their symptoms. Over the counter medication can be used to reduce fever and aches. Vitamins and complementary and alternative medicines are not recommended unless they are being used in consultation with a licensed healthcare provider.

Monitor temperature regularly

The case should monitor their temperature daily, or more frequently if they have a fever (e.g., sweating, chills), or if their symptoms are changing. Temperatures should be recorded and reported to the PHA as per their instructions. If the case is taking acetaminophen (e.g. Tylenol) or ibuprofen (e.g. Advil), the temperature should be recorded at least 4 hours after the last dose of these fever-reducing medicines.Footnote h

Maintain a suitable environment for recovery

The environment should be well ventilated and free of tobacco or other smoke. Airflow can be improved by opening windows and doors, as weather permits.

Stay connected

Staying at home and not being able to do normal everyday activities outside of the home can be socially isolating. PHA can encourage people who are isolating themselves at home to connect with family and friends by phone or computer.

Precautions for household members (e.g. caregivers, roommates) to prevent transmission to others in the home

It is important to for others in the home take appropriate steps to protect themselves against COVID-19.

Eye Protection

Eye protection is recommended to protect the mucous membranes of the eyes during case care or activities likely to generate splashes or sprays of body fluids including respiratory secretions.

  • Eye protection should be worn over prescription eyeglasses. Prescription eyeglasses alone are not adequate protection against respiratory droplets.
  • Protective eye wear should be put on after putting on a mask.
  • After applying eye protection, gloves should be donned (see below).
  • To remove eye protection, first remove gloves and perform hand hygiene. Then remove the eye protection by handling the arms of goggles or sides or back of face shield. The front of the goggles or face shield is considered contaminated.
  • Discard the eye protection into a plastic lined waste container. If the eye protection is not intended for single use, clean it with soap and water and then disinfect it with approved hard-surface disinfectants that have a Drug Identification Number (DIN). A DIN is an 8-digit number given by Health Canada that confirms the disinfectant product is approved and safe for use in Canada. When approved hard surface disinfectants are not available, for household disinfection, a diluted bleach solution can be prepared in accordance with the instructions on the label, or in a ratio of 5 millilitres (mL) of bleach per 250 mL of water OR 20 mL of bleach per litre of water. This ratio is based on bleach containing 5 % sodium hypochlorite, to give a 0.1 % sodium hypochlorite solution, being mindful not to contaminate the environment with the eye protection.
  • Perform hand hygiene.

Gloves

Disposable single use gloves, if available, should be worn when in direct contact with the ill person, cleaning contaminated surfaces, and handling items soiled with body fluids, including dishes, cutlery, clothing, laundry, and waste for disposal. Gloves are not a substitute for hand hygiene; caregivers must perform hand hygiene before and after putting on and taking off gloves.

  • Gloves should be removed, hand hygiene performed, and new gloves applied when they become soiled during care.
  • To remove gloves safely, with one of your gloved hands pull off your glove for the opposite hand from the fingertips, as you are pulling, form your glove into a ball within the palm of your gloved hand. To remove your other glove, slide your ungloved hand in under the glove at the wrist and gently roll inside out, and away from your body. Avoid touching the outside of the gloves with your bare hands.
  • Gloves must be changed and hand hygiene performed when they are torn.
  • Discard the gloves in a plastic-lined waste container.
  • Perform hand hygiene.
  • Double-gloving is not necessary.

Reusable utility gloves may be used; however, they must be cleaned with soap and water then disinfected after each use with approved hard-surface disinfectants that have a Drug Identification Number (DIN). A DIN is an 8-digit number given by Health Canada that confirms the disinfectant product is approved and safe for use in Canada. When approved hard surface disinfectants are not available, for household disinfection, a diluted bleach solution can be prepared in accordance with the instructions on the label, or in a ratio of 5 millilitres (mL) of bleach per 250 mL of water OR 20 mL of bleach per litre of water. This ratio is based on bleach containing 5 % sodium hypochlorite, to give a 0.1 % sodium hypochlorite solution.
