Tumbling COVID-19 case counts have some schools around the U.S. considering relaxing their mask rules, but deaths nationally have been ticking up over the past few weeks, some rural hospitals are showing signs of strain, and cold weather is setting in.

The number of new cases nationally has been plummeting since the delta surge peaked in mid-September. The U.S. is averaging about 73,000 new cases per day, less than half of the nearly 173,000 recorded on Sept. 13. And the number of Americans in the hospital with COVID-19 has plummeted by about half to around 47,000 since early September.
