So you’ve decided to wear a face mask but do you know how to use one correctly? Here are a few tips.

 

    Not all face masks are created equal. Loose-fitting surgical or medical masks made of soft, thin cloth are meant to prevent bacteria, which are larger than viruses, from spreading from medical workers to patients. Form-fitting masks, also known as N95 respirators, are made of spun plastic fibers that filter smaller particles. A study in The Lancet journal found that use of N95 masks during the SARS outbreak gave Hong Kong hospital patients up to 13 times more protection than not wearing one.

 

    When worn by infected individuals, both kinds of masks are effective in preventing the spread of droplet infections. Both also act as a barrier to large droplets of mucus others may sneeze or cough at you.

 

    Local pharmacies are currently out of surgical masks, though health authorities hope to address the shortage by next Tuesday. If you have friends north of the border that are willing to send a care package and you’re worried about infection, N95 masks cost a few dollars each and can be worn up to a week. They need to provide a tight facial seal to be effective.

 

    Your mask should cover your mouth and nose fully.

 

    Once your mask is on, avoid touching it, and wear it consistently (no sliding it on and off repeatedly), or germs from your hands will permeate the material. This will be harder with N95 masks, which can be uncomfortable and impede breathing.

 

    If you must touch your face mask, wash your hands before and after touching it.

 

    Your hands are transmittors – wash them frequently and avoid touching your mouth, nose or eyes.

 

    Generally, surgical face masks should be changed daily, but replace masks immediately if they are damaged or soiled.

 

    Are you committed to doing things right? Place used face masks in a plastic bag and tie it tightly before throwing in the garbage.
