A powerful argument for wearing a mask, in visual form
Most people here are wearing masks on buses now, but in my area the percentage of people wearing masks all or most of the time outside would be way off the graph at the left. From a rough count i'd guess around 20%, if that. Guess that's because we haven't had a report of a new case for months. That's in my postcode.
Real-time pandemic data paints a vivid picture of the relationship between mask-wearing and the prevalence of covid-19 symptoms

Despite the clear opposition to masks within the Trump White House and among its allies, Americans of all political stripes overwhelmingly support their use as a public health measure and say they wear them whenever they’re in public.
Still, there are significant differences in mask-use rates at the state level. And data from Carnegie Mellon’s CovidCast, an academic project tracking real-time coronavirus statistics, yields a particularly vivid illustration of how mask usage influences the prevalence of covid-19 symptoms in a given area. Take a look.
For all 50 states plus D.C., this chart plots the percentage of state residents who say they wear a mask in public all or most of the time (on the horizontal axis) and the percentage who say they know someone in their community with virus symptoms (on the vertical axis). If you’re curious about the exact numbers for your state, there’s a table at the bottom of this article.
Take Wyoming and South Dakota, for instance, in the upper left-hand corner of the chart. Roughly 60 to 70 percent of state residents report frequent mask use, as shown on the bottom axis, which puts them at the bottom for mask rates. They also have some of the highest levels of observed covid-19 symptoms, approaching 40 and 50 percent.
Now, note what happens as you move across the chart. States farther to the right have higher rates of mask use. And as mask use increases, the frequency of observed covid-19 symptoms decreases: More masks, less covid-19.
This relationship is called a correlation, and it’s a strikingly tight one. Often in these types of plots you have to squint really hard to suss out such a relationship, and researchers occasionally go to comical lengths to divine the presence of a correlation where none really exists.
