US Covid infections rising again as upper midwest sees biggest jump

Increase comes ahead of Thanksgiving as families gather in homes, and as winter approaches, forcing people indoors

America's Covid-19 infections are climbing again, and could soon hit a weekly average of 100,000 cases a day as daily case reports increase more than 20% across the upper midwest.

The fresh worsening of the coronavirus pandemic in the US comes as temperatures cool during the approach of winter, forcing people indoors where the virus is believed to spread more readily and may presage another wave.
