Facemasks such as surgical masks or N95 respirators should be saved for healthcare workers and other medical first responders. Those who had masks before the Coronavirus outbreak started, may choose to wear them when seeking essential services.
This is how to wear your facemask safely:
Wear the mask in a public setting when it is hard to maintain social distancing
Throw away the mask if it is dirty, damaged, or hard to breathe through.
Facemasks should be stored with the outer surface folded inward against itself to reduce contact with other surfaces during storage
Folded masks should be stored in a clean paper bag or breathable container
Each mask should be worn by only one person
Clean hands with alcohol-based sanitizer before and after touching or adjusting the mask for wear. Wash hands as soon as possible after taking the mask off.
Do not touch the outside of the facemask. If contact occurs, wash or sanitize hands as soon as possible
