Confirmed cases rising in 40 of 50 states

The surge has been blamed in part on Americans not covering their faces or following other rules.

The number of confirmed coronavirus cases per day in the U.S. climbed to an all-time high of more than 50,000 on Thursday, with the infection curve rising in 40 of the 50 states in a reversal that has largely spared only the Northeast.

An alarming 36 states are seeing an increase in the percentage of tests coming back positive for the virus.

“What we’ve seen is a very disturbing week,” Dr. Anthony Fauci, the government’s top infectious-disease expert, said in a livestream with the American Medical Association.

In a major retreat that illustrated how dire things have become in Texas, Republican Gov. Greg Abbott ordered the wearing of masks across most of the state after refusing until recently to let even local governments impose such rules.

The surge has been blamed in part on Americans not covering their faces or following other social distancing rules as states lifted their lockdowns over the past few weeks. Fauci warned that if people don’t start complying, “we’re going to be in some serious difficulty.”

The U.S. recorded 50,700 new confirmed cases, according to a tally kept by Johns Hopkins University. 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 New York metropolitan area was easily the worst hot spot in the U.S.

All but 10 states are showing an upswing in newly reported cases over the past 14 days, according to data compiled by the volunteer COVID Tracking Project.

The outbreaks are most severe in Arizona, Texas and Florida, which together with California have reclosed or otherwise clamped back down on bars, restaurants and movie theaters over the past week or so. Nebraska and South Dakota were the only states outside the Northeast with a downward trend in cases.

While some of the increases may be explained by expanded testing, other indicators are grim, too, including hospitalizations and positive test rates. Over the past two weeks, the percentage of positive tests has doubled in Georgia, Kansas, Montana, Michigan, Missouri, Tennessee, Mississippi, South Carolina and Ohio. In Nevada, it has tripled. In Idaho, it is five times higher.

In Texas, where new cases in the past two weeks have swelled from about 2,400 a day to almost 8,100 on Wednesday, the positive rate ballooned from 8% to 14.5%.

In Arizona, it has gone from 5.7% to 10.3%.

Abbott, who in May began one of the most aggressive reopening schedules of any governor, ordered the wearing of masks in all counties with at least 20 COVID-19 cases.

Abbott said in a video posted on Twitter that the state’s lower infection rate and case counts after his stay-home order in April might have led some to think the “coast was clear.”

But the number of people hospitalized in Texas because of COVID-19 has tripled since late May, after businesses began reopening.

“We are now at a point where the virus is spreading so fast, there is little margin for error,” Abbott said. “I know that wearing a face covering is not the convenient thing to do, but I also know that wearing a face covering will help us to keep Texas open for business. And it will help Texans earn the paycheck they need.”
