Concerns over new Covid subvariant as holidays approach

(Undated)  --  Officials say a new COVID-19 subvariant is on the rise this holiday season.

The CDC says cases of the new variant, which has been dubbed JN-point-one, now account for about a third of new infections in the Northeast, versus 20-percent of the cases nationwide.  

According to the CDC this new variant will become the dominant strain within weeks, owing to the fact that cases have doubled between mid-November and the middle of this month.

Studies out of Columbia suggest this variant is eluding immunity, although there is not evidence the new variant has significantly different symptoms or causes more serious illness than other circulating variants.  

The new variant comes as there's a jump in other respiratory viruses.
