Brief Summary:
A randomized controlled trial in which nurses will be randomized to either medical masks or N95 respirators when providing care to patients with COVID-19.

Condition or disease Intervention/treatment Phase
Coronavirus N95 Medical Mask Device: Medical Mask Device: N95 respirator Not Applicable

Detailed Description:
A randomized controlled trial in which nurses will be randomized to either medical masks or N95 respirators when providing medical care to patients with COVID-19. This Canadian multi-centre randomized controlled trial will assess whether medical masks are non-inferior to N95 respirators when nurses provide care involving non-aerosol generating procedures. Nurses will be randomized to either use of a medical mask or to a fit-tested N95 respirator when providing care for patients with febrile respiratory illness. The primary outcome is laboratory confirmed COVID-19 among nurse participants.
