A new tool developed by Georgia Tech allows people to look up their risk of encountering COVID-19 at event, based on the county they live in.
The interactive map allows users to choose a county anywhere in the United States, choose the event size (anywhere from 10 people to 10,000), and then calculate the risk that at least one COVID-19 positive person will be present.
For example, in Hennepin County, the tool calculates that at a 100-person event, there is an 80% chance that someone in attendance will be COVID-positive. At a gathering with only 10 people, that risk goes down to 15%.
In Cook County, the home of Grand Marais and the northeastern-most county in the state, the risk level is less than 1% at a gathering with 100 people in attendance. Alternatively, the risk is over 99% in three Minnesota counties: Grant, Pipestone and Watonwan.
The Minnesota Department of Health (MDH) has been doing community testing in Watonwan County based on the spike in cases there.
The interactive map is based on data from The COVID Tracking Project at The Atlantic, which pulls daily data on COVID-19 testing and patients from all 50 states. It's also based on 2019 U.S. Census data.
