The US broke its single-day record for new cases at least 9 times in a month. This is how the crisis spiraled

In the past few weeks, hospitals across the country have reached capacity. At least 27 US states have halted or rolled back their reopening plans to slow the spread of the virus. New estimates from US Centers for Disease Control and Prevention say at least 40% of people who get the virus could show no symptoms, meaning thousands of Americans could be unknowingly still infecting others.

Now, officials point to gatherings and crowded bars as some of the major drivers of the surge. To prevent further spikes, parts of the country -- including Arizona, California and Texas -- have closed bars back down. Local leaders have begun pushing schools to remote instruction in the fall, after outcries from terrified parents and educators. Across the country, more mask requirements are going into effect, despite consistent backlash from some Americans. Face masks, experts have said, are the most powerful weapon against the virus.

With the surge in cases, models are projecting more than 150,000 American deaths will be linked to the virus by August 8, according to an ensemble forecast published by the CDC. The previous forecast published July 9 projected roughly 147,000 deaths by August 1.

At least 140,119 Americans have died of the virus, according to Johns Hopkins University. There have now been more than 3.7 million cases in the country.

Florida Gov: No prosecution for those not wearing masks

In Florida, Gov. Ron DeSantis has resisted implementing a statewide mask mandate and said Saturday the state would not be "prosecuting people" for not wearing masks.

When asked about the possibility of stricter face mask regulations throughout the state, DeSantis said face coverings have been advised since the state's first phase of reopening.

"When you're living your life and trying to open up the country, you are going to come into contact with people, and for that reason, we know that masks are really important, and we should be using them everywhere," he said.

Experts say Florida's numbers are trending in an alarming direction. In Miami-Dade County, intensive care units are at about 122% capacity, according to county data. In the past two weeks, the county has seen a 40% increase in the number of coronavirus patients being hospitalized and about a 64% increase in the use of ventilators, according to the data.

"It's really a crisis moment at (Miami's Jackson Memorial Hospital)," Martha Baker, the president of a union representing health care professionals, told CNN affiliate WFOR. "We're just, I say dancing on the head of a pin, hoping we can keep dancing."

"Fifteen nurses in the ICUs alone called in sick today, just at Jackson Main," she told the affiliate. "They're exhausted. They've been doing this since March."

The state reported 12,478 new cases Sunday, the Florida Department of Health said. It is the fourth time the state has reported more than 12,000 new cases in a day. It now has more than 350,000 cases, and 4,982 deaths, state data shows.

Texas reports more than 10,000 cases for fifth day

In Texas, similar calls for help came from healthcare professionals as cases continue to climb across the state.

"At any given time if 1.5% of the population had Covid disease, that would fill every single adult hospital bed in the city, leaving no room for heart attacks and strokes and pregnant women who are having their babies and car accidents and everything else that continues to go on," said Dr. David Persse, with the Houston Health Department, according to CNN affiliate KPRC.

Harris County, where Houston is located, has reported more than 54,800 cases of the virus.

For the fifth day in a row, Texas reported more than 10,000 new cases in a day, according to state data. The 10,158 new cases reported Saturday bring the state's case tally to at least 317,730.

Gov. Greg Abbott, who once pushed for one of the most aggressive reopenings, has in recent weeks advocated for the use of face masks to help businesses stay open.

Earlier this month, he issued an executive order requiring residents in counties with 20 or more active cases to wear face coverings in public. The order took effect July 3.

Several states reconsidering masks

Texas isn't the only state promoting the importance of wearing masks. Mississippi Gov. Tate Reeves issued a mask mandate in 13 of the state's 82 counties and told CNN he would institute it statewide if he believed it would save lives.

Health agencies did not advise wearing masks at the beginning of the pandemic, and now they do, "so it's a complicated process," the governor said.

"If we will do the little things," Reeves said, "we can make a difference in slowing the spread of this virus. The best way to do that is to highlight those counties where it's most needed."

He noted that Los Angeles had a mask mandate and has more cases than Mississippi. The California city saw record single-day new cases and hospitalizations last week.

LA Mayor Eric Garcetti is "on the brink" of issuing another stay-at-home order, he said. Garcetti defended his leadership during the crisis, pointing to the city's testing initiatives and mask mandate, but said many factors were beyond his control and took aim at the White House, citing "the lack of national leadership."

"I think that there are people who are just as exhausted. They were sold a bill of goods. They said this was under control. They said this would be over soon, and I think when leaders say that, people react and they do the wrong things. They stop distancing themselves. They stop washing their hands. They stop wearing masks," Garcetti said.

In Ohio, Gov. Mike DeWine also stopped short of a statewide order, but the state has begun a campaign to encourage residents to wear masks. Covid-19 is spreading in bars, churches, casual settings and via out-of-towners, and he worries Ohio could follow Florida's path, he told NBC's "Meet the Press." It's important his constituents realize wearing a mask is about protecting everyone, he said.

"You wear the mask to protect your grandmother," DeWine told NBC. "The orders are obviously important, but getting people to buy in and to understand -- getting a 20-year-old to understand that he or she may feel invulnerable, nothing is going to happen to them, but they may get it. They may not know they have it. They may go home and see their grandmother. She may get it, and she may end up dying."

While some states are resisting making masks mandatory for all residents, Arkansas Gov. Asa Hutchinson says he understands the sentiment but has no choice.

"Not something I wanted to do," he told ABC, "but it's something everyone can do to relieve pressure on hospitals, to give us a hope to bring down those cases."

He added, "It's not the first lever we pull, but it is one that when the data says it's necessary, we do it."
