I've been absolutely speechless I don't know how many times watching international news channels. Professionals and volunteers alike wearing ill fittings masks and gloves either regularly touching their masks to adjust them or sometimes they're not even on properly and just cover the mouth and not the nose. Even some professionals struggle with it because they're so busy and under pressure they make very simple mistakes without thinking. The whole concept is so new to most of the general public that mistakes are guaranteed. The problem is this is so serious mistakes can cost lives.
If the general public are ever advised as a whole to wear masks there would need to be an intense advertising campaign on all TV channels explaining proper use and cross contamination. But most would still struggle and mess up.
