Happy to answer your question. While I realize that you are making fun by saying "so deadly and contagious", COVID-19 does seem to be 7-9X more contagious that influenza (seasonal flu), so even if it has the same mortality rate as flu, more people are going to die just because it is so much more contagious. Math.
We have learned a great deal over the past 6 months. We know the essentially all transmission is via respiratory droplets. In normal conversation, these typically can travel about six feet from an infected person. Data on singing and cheering/yelling shows that droplets can go significantly farther, so I assume this is the rational for wearing masks in the stadium. Simple masks are shown to stop 90% of respiratory droplets.
Concerning biohazard bins, again because transmission is by respiratory droplets instead of contact, as long as you don't reach into a trash can, pull out a mask immediately discarded by an infected person, put it on your face and inhale as hard as you can, I think you will be fine.
