Coronavirus live updates: CDC clarifies guidelines on contact spread; New York trends improve; NHL reveals reopening plan

The Centers for Disease Control and Prevention provided more detail on the possibility of coronavirus being spread by contact, while the NHL unveiled its plan to restart the season and New York had some optimistic news about how the state is dealing with the pandemic.

U.S. stocks roared higher Tuesday amid optimism that national and global economies were slowly awakening from their slumber despite a WHO warning that the world remains in the "first wave" of the pandemic. Still, states were beginning to open back up – although some large gatherings, such as a pool party at Lake of the Ozarks in Missouri, drew ire from health officials.

The United States is inching closer to a devastating milestone as the virus will soon be blamed for the deaths of 100,000 Americans. There are more than 5.5 million confirmed cases around the globe, with nearly 1.7 million in the United States alone, according to the Johns Hopkins University data dashboard. More than 350,000 people have died worldwide.

Los Angeles opens largest coronavirus testing site in US at Dodger Stadium

The city of Los Angeles opened its biggest testing site at Dodger Stadium on Tuesday, which can test up to 6,000 people daily for free. It's the largest site in the U.S., according to Community Organized Response Effort, a non-profit organization that helps vulnerable communities during a crisis.

“Dodger Stadium is a place where Angelenos usually rally around a common goal of victories on the field –– and today, it is uniting us around a mission to save lives,” Los Angeles Mayor Eric Garcetti said in a statement.

Garcetti worked with several organizations – including Community Organized Response Effort, the Dodgers and others – to open the site. The Community Organized Response Effort has worked with state and city officials to open 12 sites in Los Angeles, and 28 sites across the nation.

Los Angeles was the first U.S. city to offer free testing to all residents, whether they had symptoms or not.

CDC clarifies guidelines on how coronavirus spreads

The Centers for Disease Control and Prevention released an update to their recent changes to the coronavirus guidelines. Two days after the guidelines said COVID-19 "does not spread easily" by touching contaminated surfaces or objects, the CDC clarified that the wording they used was "confusing."

"This change was intended to make it easier to read, and was not a result of any new science," the CDC said in a news release.

The agency had always warned that "it may be possible" to become infected with coronavirus by touching contaminated surfaces or objects although the primary way to get infected is through person-to-person contact. That statement still holds true with the recently updated guidelines saying: "This is not thought to be the main way the virus spreads, but we are still learning more about how this virus spreads."

NHL unveils plan to restart with 24-team postseason tournament

The NHL took a big step Tuesday toward completing its 2019-20 season amid the coronavirus pandemic. Commissioner Gary Bettman announced a 24-team playoff format that was accepted by the Players’ Association through a vote that concluded Friday.

The tournament will feature the top 12 teams in each conference, with seeds based on points percentage and calculated using every team’s record at the time of the pause. The top four seeds in each conference would automatically advance to the traditional round of 16, but seed Nos. 5 through 12 would have to play their way in.

The tournament will be played in two hub cities to be announced at a later date, Bettman said – one for the Eastern Conference playoffs and one for the Western Conference playoffs.

Nevada Gov. Steve Sisolak cancels speech after possible coronavirus exposure

Nevada Gov. Steve Sisolak was expecting to give a speech Tuesday on the state's transition plan to Phase 2. However, the event was canceled after the governor was potentially exposed to the coronavirus.

A statement from Sisolak spokesperson Meghin Delaney said Sisolak had visited an unnamed workplace where an employee – who was not in the building at the time – later reported testing positive for COVID-19.

Delaney said the governor is scheduled to take coronavirus test on Wednesday morning. Sisolak later tweeted he had not experienced any virus symptoms in the five days since the potential exposure.

Broadway star Nick Cordero shows 'some improvements' in COVID-19 fight

Nick Cordero's wife shared a health update Tuesday, citing "some improvements" for the Broadway star, who has been hospitalized for almost two months after suffering complications from the coronavirus.

"They saw some success with proning Nick," Amanda Kloots said on her Instagram Stories, referring to a treatment technique being used amid the pandemic, where a patient is placed flat on their stomach with their chest and face down, as opposed to laying on their back, according to Health.com. "So they are going to continue doing that with him... There’s like 16-20 hour intervals that they do that. They are seeing some improvements with his oxygen and gas exchange rates when they do that. So that was really good and promising."

Kloots said her husband has also been given "new antibiotics" and "a high dose of vitamin C" to aid his immune system. "All these little things seem to be slowly helping," she said.

Cordero was admitted to Cedars-Sinai Medical Center in Los Angeles in late March. Cordero has since faced several coronavirus complications, including a leg amputation and the insertion of a temporary pacemaker.

States are reopening, but many require travelers to self-quarantine

States are slowly beginning to open back up, but that doesn't mean travelers are free to come and go as they please. USA TODAY has an update on the states that discouraged interstate travel by requiring or recommending that visitors and residents returning from other states quarantine for 14 days.

Supreme Court refuses to block order demanding action against coronavirus at Ohio prison

The Supreme Court refused the Trump administration's request Tuesday to block a lower court order requiring stepped-up efforts against the spread of the coronavirus at a low-security federal prison in Ohio.

The high court's action represented its most significant intervention to date related to the deadly impact of COVID-19 inside federal prisons.

The low-security Elkton Federal Correctional Institution in northeast Ohio faces a potential large-scale transfer of elderly, medically vulnerable inmates to less dangerous types of custody, including home confinement, under a federal court order. As many as 837 inmates could be affected out of a total prison population of some 2,500.

The high court refused to put the evaluation of those inmates on hold at the request of the Trump administration, "without prejudice to the government seeking a new stay if circumstances warrant." Associate Justices Clarence Thomas, Samuel Alito and Neil Gorsuch would have granted the administration's request.

Gov. Ralph Northam: Virginians must wear face coverings in public indoor spaces

Virginia Gov. Ralph Northam said Tuesday that everyone in the state “will need to wear a face covering” when present in any indoor space that is open to the public, starting Friday. “I’m taking this step because science increasingly shows us the virus spreads less easily when everyone is wearing face coverings,” Northam said.

Northam said there will be exceptions for those who are eating or drinking, exercising, have a health condition that prevents them from wearing one and for children younger than 10. Northam said that to prevent criminal citations, the order will be enforced through the Virginia Department of Health, rather than through law enforcement.

Northam’s announcement came after he was widely criticized for appearing in a crowded area in Virginia Beach over the weekend while he was not wearing a mask and not observing social distancing. Northam said he had left his mask in the car and was “unprepared” to encounter a crowd, but that he took “full responsibility.”

Northam said he expects Northern Virginia to advance to Phase 1 of the state’s reopening plan Friday, but that details would be available Wednesday.

Gov. Andrew Cuomo: New York state deaths ‘lowest level we have seen’

As New York continues to ramp up its reopening plan, two vital coronavirus metrics have dropped to the lowest levels since the outbreak began, New York Gov. Andrew Cuomo said Tuesday. New coronavirus hospitalizations dropped to “the lowest level since this started, just about 200," and the state reported 73 deaths Monday.

“In this absurd, new reality, that is good news,” Cuomo said.

Cuomo said he is scheduled to meet with President Donald Trump on Wednesday in Washington to ask for funding to bolster the state’s infrastructure projects. To resurrect New York’s economy and to capitalize on lower ridership from commuters, Cuomo said he wants to fast-track construction projects, like those at LaGuardia Airport and Penn Station.

“You want to restart the economy, you want to reopen the economy, let’s do something creative, let’s do it fast, let’s put Americans to work and let’s make America better,” Cuomo said. “It is common sense.”

Ozarks pool party-goers should self-quarantine, health official says

Anyone who failed to practice social distancing and other guidelines at a mega pool party in Missouri should self-quarantine for 14 days "if they have any compassion for others," Kansas City Health Department director Rex Archer said. The party Saturday in Lake of the Ozarks, about 130 miles southeast of the city, drew national attention after a video went viral showing hundreds of swimsuit-clad partygoers in extremely close quarters.

St. Louis County Executive Sam Page asked his Public Health Department to issue a travel advisory as workers return to their jobs after ignoring social distance practices. Page said the "reckless behavior endangers countless people and risks setting us back substantially from the progress we have made in slowing the spread of COVID-19."

Dire warning: 'We're in the middle of the first wave globally'

The risks of reigniting coronavirus outbreaks are complicating efforts to fend off further misery for the many millions who have lost jobs, with a top health expert warning that the world remains in the midst of a “first wave” of the pandemic.

“Right now, we’re not in the second wave. We’re right in the middle of the first wave globally,” said Dr. Mike Ryan, a World Health Organization executive director.

Ryan, speaking at a virtual news conference, pointed to South America, South Asia and other areas where the number of infections is still on the rise. For nations that appear to have peaked or plateaued, Ryan warned that a second wave is possible a few months later. He urged Europe and North America to continue with a "comprehensive strategy to ensure that we continue on a downward trajectory and we don’t have an immediate second peak.”
