Show HN: A calculator for coronavirus exposure risk in groups

I wrote this to help my girlfriend and I assess risk of exposure to someone with COVID now that our state (NY) has largely overcome the virus. Also to help us compare what we do here to what our friends are doing in other states.

Next I would like to expand it to cover our countries with it's presets and allow you to select your individual US county which is often much more interesting than the state-level numbers.

Welp never going to a grocery store again.
