Ontario health officials are changing a key recommendation on the use of hospital personal protective equipment (PPE) in response to the “potential” that the highly-transmissible Omicron variant can spread at a distance through the air.

Health-care workers providing care to a “suspected or confirmed” COVID-19 patient in hospitals, long-term-care homes, or in a home-care situation will now be required to also use a “fit-tested, seal-checked N95 respirator,” according to interim guidance issued by Public Health Ontario Wednesday.
