This tip sheet is for employers, managers, and workers in long-term care, including retirement homes and long-term care facilities.
Respiratory infectious diseases (RIDs), such as COVID-19, influenza, and respiratory syncytial virus (RSV), are caused by pathogens (germs). Many people who get sick with respiratory infectious diseases experience mild symptoms and recover fully. Still, some vulnerable individuals (e.g., immunocompromised, older, pregnant, etc.) are at risk of severe complications and death.
Infected individuals can spread pathogens through respiratory particles when they cough, sneeze, speak, sing, shout, or breathe. Some infected people display no symptoms but are still contagious (asymptomatic). People can become infected when they inhale particles that contain pathogens or by touching contaminated surfaces and then touching their eyes, nose, or mouth with unwashed hands.
Refer to guidance from the Public Health Agency of Canada (PHAC) and the Canadian Centre for Occupational Health and Safety (CCOHS) for general respiratory infectious disease prevention practices:
Provide the highest quality indoor ventilation by:
Setting the heating, ventilation, and air conditioning (HVAC) system to the greatest number of air changes per hour (refer to an accepted standard on ventilation
Opening external windows to allow outside air in, if weather permits and there is no risk to the health and safety of residents and others
Installing and maintaining an air purifying unit where ventilation options are limited
Keeping local exhaust fans (e.g., bathroom exhaust fans) on more frequently and for a longer duration
Install hand sanitizer dispensers in high-traffic and high-touch areas (e.g., main entrance, entrances to lounges and dining rooms, outside washrooms, break rooms, cafeterias, or other communal areas)
Communicate (e.g., using posters, by email, or verbally) to all workers, including students and volunteers, and visitors that people who have symptoms of a respiratory infectious disease should not enter or stay the facility
Comply with any legislative requirements that apply to long-term care operators in your jurisdiction
Reduce the amount of paper documentation or other items being exchanged between workers. Consider exchanging documents electronically. If this exchange cannot be avoided have workers wash or sanitize their hands after handling items
Consider limiting the use of equipment (e.g., computers, tools, wheelchairs, lift assist device, etc.) to one worker or resident, especially when the equipment is difficult to clean and disinfect. If equipment must be shared, clean and disinfect it between users. Make sure all workers are trained on proper cleaning and disinfecting techniques
Clean and disinfect high-touch surfaces at a scheduled frequency (e.g., doorknobs, handles, railings, tables)
Consider active or passive screening of all entrants (including workers) to the facility and recommend that anyone with a respiratory infectious disease wear a suitable respirator or mask, if possible. Non-essential individuals experiencing symptoms of a respiratory infectious disease should be discouraged from entering (e.g., visitors)
As an additional precaution or if it is required by the local jurisdiction, require mask wearing for workers, residents, and visitors whenever they are in common indoor spaces
When caring for a resident who has or may have a respiratory infectious disease:
Conduct a point-of-care risk assessment before any interaction with the resident. The assessment can also identify the required personal protective equipment (PPE) for the task
Keep residents that have a respiratory infectious disease separate from those who do not
Make sure workers know to take precautions before having close contact with the resident
Require all workers and visitors who enter the room to wear appropriate PPE
Provide the recommended PPE to those who must enter the room
Consider having the resident eat all meals in their room (i.e., have meals delivered)
Safely dispose of any contaminated PPE and wash hands with soap and water after leaving the patient’s room
Considerations for clothing and linens:
Encourage workers to wear clean clothing each day. Soiled clothes and uniforms should be washed before they are worn again, either at home or by a laundry service
Place soiled items into a lined container (e.g., hamper) with a lid
Transport soiled items in a sealed container to the washing facility and do not shake them out before adding them to the washing machine
Machine wash laundry using the hottest water setting, use laundry detergent and dry thoroughly
Keep clean items separate from soiled ones
During a facility respiratory infectious disease outbreak:
Restrict facility access to essential personnel and visitors only (e.g., religious leaders, healthcare providers, immediate family)
Suspend ongoing non-essential external services such as animal therapy, entertainment, personal services, etc. for the duration of the outbreak
Post information at entrances and other key areas detailing outbreak specific protocols and procedures that are to be followed by all workers, residents, and visitors
Notify the local public health unit, where applicable
Establish cohorts of staff or residents that stay apart. Assign different caregivers to each cohort, if possible
Increase the frequency of cleaning and disinfecting high-touch surfaces and items
Monitor residents for respiratory infectious disease symptoms daily
Require mask wearing for everyone in the facility, including residents, unless they are eating or drinking or cannot remove the mask without assistance
Consider the Risks
Respiratory infectious disease transmission is increased when individuals are exposed to several risks at once, such as when:
Working in crowded, poorly-ventilated indoor spaces
Person-to-person interactions are long and frequent
Sick individuals are present in the workplace
No access to cleaning facilities and products
Shared surfaces and objects are touched frequently
Seasonal increases in respiratory infectious disease hospitalizations or cases occur
Consider all possible respiratory infectious disease exposure scenarios in your setting and perform a risk assessment. Develop or use an existing risk assessment form to document and evaluate all work-setting characteristics, activities, and job roles. It is good practice to review your assessment regularly (at least annually or whenever something changes) to check your control methods are still effective.
Sample questions to ask during a respiratory infectious disease risk assessment:
Are indoor spaces properly ventilated?
Where do individuals gather?
What activities require interactions, communication, or touching shared objects?
How long and frequent are interactions between people?
What are the high-touch surfaces and shared objects?
Which workers are more vulnerable?
Do individuals normally participate in activities that create respiratory particles (e.g., singing, shouting, etc.)?
Are people expected to stay in an enclosed space for an extended duration?
Does a sick leave policy exist that encourages ill workers to stay home?
Control Measures
Meet your legal occupational health and safety obligations by doing everything reasonably possible in the circumstances to protect workers and ensure the health and safety of the workplace.
To provide workers with the highest level of protection, use multiple workplace controls and personal protective measures in a layered approach. No single measure is entirely effective alone. Be careful not to create new hazards or negatively impact existing controls. Review and adjust measures as necessary in consultation with the health and safety committee or representative.
The selected control measures must be based on the assessed risk to workers. Each workplace and even workers within the same workplace can have different risk levels. Workers at high risk of serious complications may require accommodation.
Consider creating an emergency preparedness and response plan that provides guidance on preventing, detecting, and responding to respiratory infectious diseases in the workplace. It can be written in the form of policies and procedures.
Vaccination
Vaccines work by stimulating an immune response from the body to help protect people from serious diseases.
Consider promoting respiratory infectious disease vaccination among eligible workers, if available
Consider providing support for workers:
To attend local vaccination clinic appointments if these times occur during work hours
Experiencing temporary side effects from vaccination
Maintain workplace controls and personal protective measures even if most workers are fully vaccinated
Ventilation
Good indoor ventilation decreases the concentration of pathogens in the air and is one of the most effective workplace control measures against respiratory infectious diseases.
Ventilate indoor spaces appropriately according to the number of occupants and types of activities
Open windows and doors to the outside if it is safe to do so
Maintain ventilation systems and seek advice from a ventilation specialist on possible improvements (e.g., increasing air exchanges per hour, reducing or eliminating recirculated air, or upgrading to air filtration and disinfection)
If possible, run ventilation systems continuously at low speed or for two hours at maximum airflow before and after buildings are occupied
Continuously run local exhaust fans in washrooms and kitchens that vent to the outside to help remove contaminated air
Make sure that air circulation or cooling fans do not direct airflow from person to person
If ventilation cannot be improved, consider using portable air filtration units with high-efficiency particulate air (HEPA) filters
Controlling the release of respiratory particles and having clean hands are effective strategies for reducing the spread of respiratory infectious diseases.
Provide hand washing stations or hand sanitizer dispensers (with a minimum 60% alcohol content) in high-traffic areas. Regularly check and restock dispensers
Encourage everyone to wash or sanitize their hands at appropriate times:
Before and after touching personal protective equipment or a mask
After touching shared or high-touch items, equipment, and surfaces
Before and after eating or handling food
After coughing, sneezing, or blowing their nose
After shaking someone’s hand
After using the washroom
Discourage individuals from touching their eyes, nose, mouth, or mask especially with unwashed hands
Reduce the number of shared objects and equipment
Do not allow workers to share personal protective equipment or masks
Reduce the number of high-touch points by having:
Motion activated doors, faucets, toilets, urinals, and lighting
Hand motion or foot pedal-activated dispensers (for soap, paper towels, sanitizer, etc.) and lined waste containers
No touch methods of tracking worker attendance such as key cards or electronic messaging
Communication and Training
Communicate new and updated workplace controls and personal protective measures to all workers in languages they understand. Specific training requirements and recommendations may vary depending on your jurisdiction. Allow workers the opportunity to ask questions and share concerns. Respond to questions and provide feedback within a reasonable time.
Train workers on specific topics related to respiratory infectious diseases, such as:
How to identify and respond to the symptoms
What to do if they become sick
Reporting requirements
Information on vaccines and options for vaccination, if possible
How to prevent the spread of the respiratory infectious disease and protect themselves at work
When to clean and disinfect, and how to safely use cleaning and disinfecting products
How to properly wear, handle, and care for personal protective equipment and masks
Depending on the surface type and environmental conditions, pathogens can remain on objects for a few hours to days.
Clean and disinfect the workplace regularly
Focus on high-touch objects and surfaces (e.g., doorknobs, handles, rails, buttons, light switches, and faucets), which should be cleaned and disinfected more often and when visibly dirty
Use approved hard surface disinfecting products
Provide adequate cleaning and disinfecting supplies and appropriate personal protective equipment
Always follow the manufacturer’s instructions when using, handling, or storing the product. Review the product’s label, and (if applicable) safety data sheet to determine what precautions to follow
Allow adequate time for workers to disinfect any shared equipment between each use
After cleaning and disinfecting:
Used cleaning cloths, towels, etc. must be properly handled to prevent cross-contamination and laundered or disposed of after every use
Deposit heavily contaminated items into plastic lined waste containers
Different screening methods can be used to identify people who could spread respiratory infectious diseases to others. Appropriate actions can be taken when screening identifies contagious individuals.
Screening is not usually required in most workplaces. When conducting active screening, people are screened before being allowed entry. Passive screening can be used in all workplace settings where individuals self-monitor and respond accordingly if they begin feeling sick. Assess your risk and determine if active or passive screening (or both) is right for your workplace.
Individuals who do not pass the screening should take appropriate actions, such as leaving the workplace or wearing a properly fitted mask if they cannot leave immediately.
Responding to Respiratory Infectious Diseases in the Workplace
Take appropriate actions to prevent the spread of a respiratory infectious disease when a sick individual is in the workplace. The risk is increased when multiple people are sick at the same time, and an emergency response may be necessary.
When any person experiences symptoms of a respiratory infectious disease while in the workplace:
Ask that they wear a mask (preferably a respirator or medical mask, or if neither is available, a well-constructed and well-fitting non-medical mask). A respirator used in this way (i.e., as source control) may not need to be fit-tested
If it is a worker, also suggest that they seek medical care
Call 911 for medical assistance if symptoms are life-threatening. If it is a worker, also notify their emergency contact
Protective equipment for respiratory infectious diseases includes respirators, medical masks, eye protection, gloves, and gowns.
Eye protection (safety glasses, goggles, or face shields) may be worn to protect from splashes. Note: face shields do not provide respiratory protection and cannot replace masks
Protective equipment policies for respiratory infectious diseases must not interfere when a higher level of protection is needed for a task
Workers may need protective equipment for protection from respiratory infectious diseases if they are:
Providing direct care or medical treatment to a person who has a respiratory infectious disease, such as COVID-19
Using cleaning and disinfecting products
Performing tasks in crowded, poorly ventilated indoor settings, and at higher risk of serious complications from respiratory infections
Note that this guidance is just some of the adjustments organizations can make during a pandemic. Adapt this list by adding your own good practices and policies to meet your organization’s specific needs.
