Nobody is presenting masks as a silver bullet. But it’s a tool to be utilised along with everything else if we have a serious intention of keeping the economy open.

The message from the science of epidemiology is clear: isolation is the only scientifically-sound measure that we have to prevent a SARS-CoV-2 infection now.
