Using multiple layers of prevention provides the best protection, especially if you can't avoid closed spaces, crowded places and close contact. Make informed choices about going out safely during COVID-19.
To keep healthy and prevent the spread of COVID-19, follow these steps:
Stay home if you're sick, even if you're fully vaccinated against COVID-19 or previously tested positive within the last 90 days (and since cleared). Learn what to do if you have symptoms. You should not attend any gatherings or events if you have any symptoms, even if they're mild.
Spend time outdoors or in well-ventilated indoor spaces. Ensure your ventilation system is in good working order. If you don't have a ventilation system, open windows to increase fresh air flow. For more information, see ventilation guidance below.
Follow local public health advice in public settings, such as wearing a face covering, screening and physical distancing
How to lower your risk and prevent the spread of COVID-19
When you get vaccinated, your natural immune response to COVID-19 is triggered. New evidence indicates people get better protection by being fully vaccinated compared to getting infected with COVID-19. If you had COVID-19, you may have some immunity, but we don't know how much or how long it may last.
The benefits of being fully vaccinated mean that you will:
Have strong protection against COVID-19. Most COVID-19 infections are in unvaccinated people. Serious illness, such as needing hospitalization or being on a ventilator, is very rare among fully vaccinated people.
Be able to do more things. You can enter settings that need proof of vaccination.
Experience less hassles and restrictions. You may qualify for exemptions related to self-isolation, testing or travel.
Physical distancing means avoiding close contact with others to prevent the spread of COVID-19. To practise physical distancing, stay two metres apart from people you don't live with. Further than two meters is better especially when:
Indoors and unmasked, such as when eating
If people in the groups are unvaccinated or if their vaccination status is unknown
To practise physical distancing:
Have virtual gatherings or events. Those who are immunocompromised or at higher risk of severe disease or exposure to COVID-19 should especially consider this.
Keeping rooms in the home well ventilated can help prevent the spread of COVID-19. Rooms in the home should be well ventilated, such as keeping windows open, if possible, and if weather permits and can be tolerated.
If you use a forced air system to heat or cool your home:
Set the system to "Fan On position" if possible
Replace your filter when needed
Upgrade to a filter with a higher MERV rating if possible
Check your owner's manual for details or consult a heating, ventilation and air conditioning (HVAC) professional before making any changes to your system
Avoid using portable fans, ceiling fans and single unit air conditioners. If you must use them, aim the air stream to avoid blowing directly at or between people in the room. Consider using fans that vent to the outside, such as a box fan in a window, a bathroom exhaust fan and a kitchen exhaust fan. Make sure you open a window when using these fans if possible.
Try to maintain an optimal humidity level, between 30 and 50 per cent in your home. A humidifier or dehumidifier can help you achieve this.
