How many of these countries offer the same level of interscholastic athletics as we do here in this country. I'll answer my own question -- ZERO. In terms of school sports, no other country does what we do to the extent that we do it. So the data is nice, but not as relevant to U.S. schools -- especially when discussing the wisdom of conducting school sports during a pandemic.
How many other countries with the data you have reviewed offer AMERICAN football, where you literally line up inches away from your opponent's face who is huffing and puffing as much as you are...where you collide together and block faceguard to faceguard?
It is mystifying to me how anyone can think this is an appropriate activity in the middle of a pandemic which has been proven to be spread primarily through the inhalation of water droplets exhaled by others.
