Midwest Cases Rise; U.K. and France Impose Curbs: Virus Update

Democratic vice presidential nominee Kamala Harris has canceled her travel until Monday after her communications director and a member of her flight crew tested positive. A passenger on Joe Biden’s campaign plane tested positive, though the two did not come near each other. New York City’s mayor reported a leveling off of infections in hot spots.

Covid-19’s recent march across the Midwest has caught up with the region’s most populous states. Illinois, Ohio and Michigan have proven unable to fend off outbreaks at their doorsteps, including in nearby Wisconsin. In Illinois, cases surged to a record 4,015 on Thursday, extending one of the nation’s most concerning weekly trends. Wisconsin and North Dakota also broke records again for daily cases.
