Tennessee governor says state is 'ground zero' for COVID surge

Tennessee Gov. Bill Lee gave a passionate plea to his constituents to avoid holiday gatherings as the number of coronavirus cases continues to rise.

The state has around 10,000 Tennesseans getting sick every day, which was three times the numbers at the end of October, the governor said during a news conference Sunday. More than 100 people are dying from the virus daily, Lee said.

"Tennessee is ground zero for a surge in sickness," he said.

Lee warned that the next few weeks will be crucial and urged families to stick to their households during Christmas and New Year's.

“We’ve seen firsthand that Thanksgiving gatherings and extended time indoors have been the leading driver in spreading COVID-19 like wildfire," he said.

Lee signed an order that limited indoor gatherings to 10 people maximum and limited attendance at indoor sporting events.

The governor urged residents to wear masks to stop the spread, however, he did not issue a state wide mask mandate.
