Coronavirus Spread In Loudoun County: See Your Risk Of Exposure

LOUDOUN COUNTY, VA —Virginia is in the midst of an increase in coronavirus cases and hospitalizations. State health officials are urging residents to celebrate Thanksgiving with their own households or take precautions when celebrating with others.

As of Nov. 15, Virginia has new measures implemented by Gov. Ralph Northam. That includes a 25-person limit on social gatherings, down from the previous 250-person limit. In addition, the governor's face mask mandate for indoor public places is expanded to include anyone five and over.

What is your risk of exposure?

Researchers from several universities have created an event risk planning tool for every county in the nation. The map shows the risk of coronavirus transmission based on an event's size and location.

A new tool shows the estimated chance — between 0 and 100 percent — that you'll encounter at least one person with the coronavirus at an event in your county. You can reduce the risk by wearing a mask, distancing and gathering outdoors in smaller groups, researchers said.

As of Tuesday, if you were to attend an event with 15 people in Hennepin County, there would be a 10 percent chance that someone at the event would have the virus, according to the COVID-19 Event Risk Assessment Planning Tool.

If you hang out with ten people, the chance drops to 7 percent.

Two Georgia Institute of Technology professors led the creation of the project, and their team included researchers from Stanford University and the Applied Bioinformatics Laboratory.

"By default we assume there are five times more cases than are being reported," the research team said in a statement. "In places with less testing availability, that bias may be higher."
