The Thanksgiving time bomb

The number of Americans driving or flying this Thanksgiving will be in the tens of millions, per AAA (though travel will be down from 2019). According to CBS, the Transportation Security Administration expects to screen six million travelers this holiday.

Canceled spring proms and graduations have been replaced with fall birthday bashes.

The same cities that closed down within days in March are now waffling over shutdowns when case counts are more than double what they were then.

The big picture: “The incoming holidays have the potential to be a real, serious problem in terms of facilitating transmission,” says William Hanage, associate professor of epidemiology at the Harvard T.H. Chan School of Public Health.
