They couldn't for a while though, and that's an aspect of the whole fiasco that really bugged me personally. The initial claim was that we do not need masks, because they are not effective and because if we all buy them then hospitals will run out, so I did not buy any. Then, we were told that we all must wear masks, and there were none available. I was re-using a disposable mask for several days at a time because I had no idea where to get them. It was really frustrating to see wealthy politicians and celebrities telling everyone to "just wear your mask!" because the rest of us could not find any to wear.
