We know that 40 %, maybe even higher, of cases are asymptomatic, meaning they don't have a fever. So, you might catch a few people, but not the vast majority of infected people, handing out masks is good, but better would be requiring masks and modeling behavior of wearing masks. And given that mask wearing has become a political statement, I think there will be social pressure not to wear a mask. In this event, the hand sanitizer is good, but I don't think you're going to stop a lot of cases that way. Most of the spread is through the air.
