Wear a Mask! And Celebrate Your Immune System

Yesterday’s XKCD “Pathogen Resistance” turns things round and shows the current crisis from the point of view of the virus. It is genius. And even has a Watchmen reference in the mouseover text.1

But more importantly, and unrelated: it turns out that wearing a mask — any kind, even just a scarf– will help to reduce the spread of the virus. This is contrary to what we were told initially, but it makes complete sense even without technical analysis. Anything coming between someone else’s droplets and your lungs, or your droplets and someone else’s lungs, is better than nothing coming between them.

It’s like wearing a cycling helmet: I’ve always thought that something between my head and the ground, should I come off, is better than nothing.

And there are designs online for making masks out of any old cloth. I feel #blessed that my daughter has an A-level in textiles and a sewing machine.

On the question of masks, though, something has been confusing me since this all started. And to an extent, before that, really, when I’d occasionally see people out and about wearing what appeared to be a hospital-style mask. Which is, where did people get such things? How did they come to have what looked like professional medical supplies in their private possession? Aren’t these things controlled?

Clearly not, for the last one. And I wondered why? Why did people have them? Now, that seems like a foolish question. And it ignores the cultural differences, whereby in parts of Asia it’s considered rude not to wear a mask if you are sick. Makes sense, though I always wonder how horrible it is if you sneeze while wearing one.
