It's a trick question. You didn't watch the video provided, because if you did, you'd realize the WHO didn't recently recommend not wearing masks as the article falsely states. They did back when the pandemic first started in early 2020 before they knew much about the virus. But ever since, these sketchy sites keep pushing it as though they said it yesterday.
Heres a link to WHO and their COVID safety recommendations:
https://www.who.int/emergencies/diseases/novel-coronavirus-2019/advice-for-public
And since i know you won't follow the link or read it, in pertinent part about MASKS from WHO:
"Make wearing a mask a normal part of being around other people. The appropriate use, storage and cleaning or disposal are essential to make masks as effective as possible.
Here are the basics of how to wear a mask:
Clean your hands before you put your mask on, as well as before and after you take it off, and after you touch it at any time.
Make sure it covers both your nose, mouth and chin.
When you take off a mask, store it in a clean plastic bag, and every day either wash it if it’s a fabric mask, or dispose of a medical mask in a trash bin.
Don’t use masks with valves.""
Please quit pushing this false info without first vetting and reseaching it.
Critical Thinking is definitely a lost skill in America. Sad.
