Florida, which health officials are predicting will be the nation's new COVID-19 epicenter, reported 8,942 new cases overnight, eclipsing Wednesday's record of 5,508.

Another Southern state, Tennessee, reported its largest single-day increase with 1,410, bringing its statewide total to 39,444 cases and 577 deaths.

Arizona, Texas, Florida and Arkansas are among the states that have been hit hard.

Deaths from the coronavirus in the U.S. are down to about 600 per day, compared with about 2,200 in mid-April. Some experts doubt deaths will return to that level, in part because of advances in treatment and prevention but also because a large share of the new infections are in younger adults, who are more likely than older ones to survive.
