Of course, masks do work. Look at Japan and South Korea where everyone out in public wears a mask. Their infection rates and death rates are very low. They have had to deal with viruses in the past like Sars virus so, they know the value of wearing a mask. If the US mandated the use of masks earlier, lives might have been saved. Infections and deaths probably, would have been much, much less.
Tell me how masks worked out in China. A country where many people wore masks in public even before COVID-19. A country where a greater percentage of the population wears masks then Japan or South Korea.
Didn’t work out well for China, eh.
