COVID-19 Event Risk Assessment Planning Tool

This is a neat, if scary, tool. On the lower left, you can choose an event size (anything from 10 to thousands of people). Then it shows you for every county in the US, what are the odds that a COVID+ person at that event?

So for example, in Harris County, at an event with 100 people, there’s a 98% chance that at least one of them has COVID. In a group of 10, there’s a 32% chance. Similar numbers for DeKalb County in Georgia.

The question then, of course, is what to do with this information.  It could influence your decision whether to engage in an activity in the first place.  Or could lead you to be extra diligent about social isolation and masks after the activity is over, because you know you could’ve been exposed.  Or, it might just make you throw up your hands and realize that you’re doomed, if you’re a classroom teacher with six periods of classes each of which contains more than two dozen students.
