The "masks don't help you unless you're sick" held up before.
Not now we know theres a high chance of asymptomatic carriers.
The worst thing the WHO did was perpuate this mask myth. They should have been honest, said yes, they can help to a degree, however at this time they need to be prioritised for HCW until supply catches up as that's the best chance of stopping this.
The "mask stigma" has prevented many who should be wearing them from doing so earlier...
