Wasn't it just two weeks ago they said healthy people don't need to wear a mask as its useless to them? The sudden about face. I know the reason was the shortage of masks, but it really damages their credibility. I think it would have been better if they said "masks help some, but we need them for health care workers go make your own for yourself".
