sorry to bring some data into this, but if we look at Wales (masks) they are increasing more than England, while Scotland (also masks) are lower. are we sure masks make the difference?
looking further, we look at age breakdown. we see seconady school is surging, primary schools rising, other age groups flat or declining.
so instead of masks, we should shut the schools?
No, masks don't make THE difference, but they do provide a marginal gain in restricting viral spread.
All marginal gains help to slow things down and mask-wearing is an easy one for most to do.
