Just that really. Facemasks have been mandatory for a couple of months now and the majority of us are wearing them. However, if they are so effective why haven't they cut the infection rate massively? Instead, we're now expericing a second wave. Even if the amount of people currently wearing Facemasks was halved, you would still expect some reduction in infection, not an increase. Surely then, this all points to the fact that Facemasks just don't work?
