> They went from near nothing to full capacity in a little over a month How can that be true if masks were already a highly available everyday product in metropolitan areas in e.g. China. Many people wore masks in winter almost every day even if they were not sick due to lower air quality. It is indeed true that they raised already existing capacities massively up, but compared to what has been produced in the US or in Europe they already had a starting point magnitudes higher.
