The U.S. on Thursday set a record for daily new COVID-19 cases with 55,220, surpassing Wednesday's record mark of 52,789. The outbreaks are most severe in Arizona, Texas and Florida, which together with California have closed again or clamped back down on bars, restaurants and cinemas.
Fauci warned that if the United States does not take control of the situation it risks "an even greater outbreak". Thursday was the 25th straight day the state set a record high in its seven-day rolling average.
The daily USA tally of cases stood at 55,274 late on Thursday, topping the previous single-day record of 54,771 set by Brazil on June 19.
OH and Arizona also reported new record highs in cases on Wednesday. The decision comes as a reversal after Abbott had previously barred local governments from penalizing people who didn't wear masks in public.
The move came after the Lone Star State reported 8,000 new cases on Wednesday, the latest in a string of records that has alarmed health authorities, and led to the governor largely halting the reopening program that started in early May.
The FDA has given authorization to proceed with clinical trials for four vaccines, Hahn said on ABC's "Good Morning America".
In June, Florida infections rose by 168% or over 95,000 new cases.
That represents a doubling of the daily total over the past month and is higher even than what the country witnessed during the most lethal phase of the crisis in April and May, when the NY metropolitan area was the epicentre of cases in the US.
While some of the increases may be explained by expanded testing, other indicators are grim, too, including hospitalisations and positive test rates. If this continues, he said Arizona "is soon going to be in considerable trouble". Abbott's order applies to all counties in Texas with 20 or more confirmed COVID-19 cases.
While testing rates have increased, so has the percentage of positive results.
On Thursday, Texas reported 7,915 confirmed cases, bringing its total to almost 176,000.
