New heat map shows risk of getting COVID-19 during Thanksgiving in every county in the US


ST. LOUIS (KMOX) - The Georgia Institute of Technology has released a map that shows the likelihood of at least one person at a Thanksgiving event being positive for COVID-19. It's broken down by every county in the U.S.

The COVID-19 Event Risk Assessment Planning Tool was created to help people get a visual look at the risks of traveling outside of your bubble during the holiday season. The map let's you toggle the "event size" so you can match the amount of people who may be at a family gathering or public event you plan to attend.

Here are the chances of someone having COVID-19 at an event in counties around the St. Louis area with 50 total people attending:

St. Louis City - 70%
St. Louis County - 84%
Jefferson County - 88%
St. Charles County - 90%
Franklin County - 83%
Monroe County - 94%
Madison County - 91%
St. Clair County - 82%
Greene County - 99%
Pike County - 99%

According to the website, the risk level is the estimated chance (0-100%) that at least 1 COVID-19 positive individual will be present at an event in a county, given the size of the event.

The Centers for Disease Control recommends that Americans celebrate with people in your own household, while wearing a mask, or outside to reduce the rise of transmitting the virus.

"Right now, a lot of us are trying to make some decisions about what we will be doing this holiday season," Mallory Harris, a Ph.D. student at Stanford who helped develop the new heat map with Georgia Tech, tells WBIR.

"Our hope is that we can turn these raw case counts that are really kind of non-intuitive to look at and turn it into something that is more familiar to people," Harris said.
