Health experts once again worried about possible COVID winter surge
As winter nears, some health officials are worried about a spike in COVID cases.
This time last year, a surge in cases filled up hospitals once again.
The omicron variant arrived in the United States just after Thanksgiving last year.
Now subvariants are causing worry among medical professionals.
COVID cases nationally sit just below 40,000 a day – far lower than last year, but likely undercounted with reduced testing and reporting.
