Masks provide an important layer of protection against respiratory viruses. The higher the levels of respiratory viruses (like influenza, RSV and SARS-CoV-2) in the community, the more important it is to wear a mask indoors when around others.

When respiratory viruses levels are high, everybody 2 years old and older is recommended to wear a mask indoors.
