A Canadian dental doctor, Olivia Cuid, has recorded a video on the popular social network TikTok in which she explains a clever trick to prevent the gap left by disposable masks on the sides once we put them on from being a route for infection of covid-19 as well as other viruses.
The trick consists of making a knot at the base of the rubber bands, in the part closest to the mask tissue, and then inserting the surplus of the same mask inside, forming a kind of muzzle which prevents the virus from entering and leaving the sides.
A simple but effective idea. You can see the video in this link:
