The primary reason for recommending mask wearing at this time is the significant number of people walking around that don't know they have it and can spread it to others. They are either presymptomatic, meaning they may feel sick tomorrow, or like a lot of folks, asymptomatic, meaning their symptoms are so mild they could write them off as allergies or nothing at all. Masks are very effective at preventing this kind of transmission. If you are saying, well what's in it for me, I don't care if I catch it or give it to someone else, keep in mind that a big outbreak is going to be really bad for the economy and the health care system. A lot of people do get very sick, and don't recover 100%. They cannot work as well as they used to. The reduction in deaths and ICU admissions was won at great cost to the residents of Michigan by staying at home. If everyone were courteous and considerate and wore masks and kept up the distancing, we could realistically keep the numbers low. But no, between the demonstrators of various sorts, including the gun rights/militia group this week, and the various groups that have foolishly turned this into a political issue, I am betting we too will have an upward surge in the numbers in a few weeks.
