The negative number of excess deaths in some Asian countries like Japan, Korea and Taiwan is interesting. I wonder if it's because of the very high rate of mask wearing that these countries have been known for since early in the pandemic. This might have helped reduce the number of deaths from influenza and other respiratory infections so much that they outweigh the deaths from Covid.
