That doesn't mean it isn't dumb as shit. Not even hospital workers are required to wear masks. The last time I went to the ER, literally nobody was wearing a mask. And hospitals are more of a breeding ground for disease than anywhere else.
Come to think of it, furcons *are* far dirtier places than hospitals, thanks to international travel and furries attending cons despite being sick.
