The U.S. daily case average has climbed to more than 84,000, a 45.3% jump in the last week, according to federal data.

The daily case average is now more than seven times higher than it was six weeks ago.

All but three states are now reporting high (a seven-day new case rate ≥100) or substantial (a seven-day new case rate between 50-99.99) community transmission, according to federal data.

The delta variant now accounts for 93% of all sequenced cases in the U.S., according to the latest CDC data, which was collected over the last two weeks of July.

Delta accounted for just 3% of cases sequenced in late May.

Across the Midwest, described as HHS regions 7 and 8, delta made up 97% to 98% of cases. This includes Iowa, Kansas, Missouri, Nebraska, Colorado, Montana, North Dakota, South Dakota, Utah and Wyoming.

The World Health Organization is calling for a moratorium on booster shots until more people from low-income countries have received a vaccine.

Low-income countries have only been able to administer 1.5 shots for every 100 people due to lack of supply, Dr. Tedros Adhanom Ghebreyesus, WHO Director-General, said Wednesday.

A moratorium on boosters until at least the end of September will "enable at least 10% of the population of every country to be vaccinated," he said.

But White House press secretary Jen Psaki said in response that the U.S. doesn't have to choose.

"We feel that it's a false choice and that we can do both," Psaki said Wednesday.

The U.S. has ordered enough supply for every American to get vaccinated, plus get a booster shot, according to the White House. The U.S. has already pledged to donate 580 million doses to the international community by 2022.

The Centers for Disease Control and Prevention forecasts that daily hospitalizations "will likely increase over the next four weeks."

About 7,000 new COVID-19 patients are hospitalized each day right now. That may soar to 24,000 per day, according to the COVID-19 Forecast Hub at U Mass Amherst.

A federal judge ruled Sunday in favor of Norwegian Cruise Line and will allow the company to require proof of vaccination on cruises out of Florida despite a state law that bans cruise ships from enacting such an order.

Norwegian sued the state last month contending that the law prevented them "from safely and soundly resuming passenger cruise operations from Miami, Florida."

Florida's law threatens to fine companies $5,000 each time they ask a customer to provide proof that they've been vaccinated.

Florida has seen a surge in COVID-19 cases and hospitalizations in the last couple of weeks, with most cases affecting unvaccinated residents.

Judge Kathleen M. Williams wrote in her decision that Norwegian "has demonstrated that public health will be jeopardized if it is required to suspend its vaccination requirement," and the Florida Department of Health, "identifies no public benefit from the continued enforcement of the Statute Case."

Neither the cruise line nor the Florida Department of Health issued immediate statements about the ruling as of Sunday evening.
