On a day (November 12) that saw South Dakota reach an all-time high for the number of new COVID-19 cases, a new interactive tool has been released to assess the coronavirus risk of each and every county in America based on the number of people at a gathering.

The website Scary Mommy is sharing a COVID-19 Risk Assessment Planning Tool designed by researchers at Georgia Tech to calculate not the odds of being infected, but rather the likelihood that at least one person in a group will be carrying COVID-19.

In South Dakota, with data available from all but one (Shannon County) of the state's 66 counties:
