Also from the CNN article:
"The Level 4 list now contains almost 120 places. In early January, there were around 80 destinations, further demonstrating the reach of the Omicron variant."
--------------
From an on the ground perspective, Omicron seems to be peaking, hospitalizations have been hovering around the mid 500's for the last week, with 575 on the high end and 480 on the lower end. This compares to late August 2021 with hospitalizations at nearly 800.
Look for the CDC to be lowering most of those 120 countries in the next few weeks as the peaks begin to drop off...
