so late? neighboring Czechia has mandatory masks (or anything covering your nose and mouth) in every public space at least for a week, I think Slovakia also already for quite long time
* In February prime minister forbid hospitals to buy face mask and decided that he will buy them centrally and than distribute them to hospitals. In the begining of March when coronavirus appeared in Czech republic he also sent finacial control against face mask importers to ensure that they are not selling anything. He wanted to look as savior of the country but he wasn't able to buy any masks so for 2 weeks there were only 10 000 mask from reserves for the whole country. People started to sew mask at home and partially saved situation. After that prime minister made wearing mask mandatory which in my opinion is mainly PR to make the home made masks look like his own initiative. He also spreads fake news about Germany, Austria and other west European countries saying that they are not responsible and that they just copy Czech measures when it is too late. But in reality his administrative is really struggling without any plan and his main efforts go to PR.
I agree it's quite pointless for healthy not coughing person, but it's just easier to order everyone to wear them than checking one by one who is sick and who is not.
not sure how is mask wasted, if it's cloth mask you can just microwave it or boil it, if it's medical mask you can just leave it on sunny surface until it's for sure clean again or microwave it, same applies to respirator
in rest of the world maximum 9 days
