Because - I can hardly believe I am still needing to explain this, 6 months into the epidemic - you have no way of knowing whether you are infectious or not. Nobody can know, on a particular day, whether or not they are "healthy", as you put it.If it stops infected people from spreading it... why are healthy people required to use it?
And, if you look at today's facemarks (from bandanas to home made masks to just cloth masks) - what does it really do except assuage people's fears?
I wear the mask often but I also know it really doesn't change anything as it is only a cloth mask.
We know for a fact that you can spread the virus before you show any symptoms, and we know for a fact you can even remain totally asymptomatic and still be infected, especially if you are under 30. So you can easily think you are "healthy", but in reality you risk spreading the virus every time you breathe out.
On the masks, a cloth mask will reduce the projection of droplets into the air around you when you exhale.
It is that simple. Nobody claims it is perfect, but then the name of the game is to get R <1. So every little thing we do contributes to that: masks, social distancing, working from home, not attending concerts (or indeed singing, much to my personal dismay)......
The more we can control the spread, the more vital activities we can allow to resume, the hot issue right now being to let the schools go back. If people don't get the message and help each other via these simple and not very onerous measures, the schools have to stay out and a generation of children will be damaged.
