(NEW YORK) — The novel coronavirus pandemic has now killed more than 579,000 people worldwide.

Over 13.3 million people across the globe have been diagnosed with COVID-19, the disease caused by the new respiratory virus, according to data compiled by the Center for Systems Science and Engineering at Johns Hopkins University. The actual numbers are believed to be much higher due to testing shortages, many unreported cases and suspicions that some governments are hiding or downplaying the scope of their nations’ outbreaks.

The United States has become the worst-affected country, with more than 3.4 million diagnosed cases and at least 136,468 deaths.

1:25 p.m.: SC governor says parents must have option of in-person school 5 days a week

South Carolina Gov. Henry McMaster said he is “calling on all the public school districts to submit reopening plans that give parents the option to send their children back to school five days a week.”

“Or, parents can choose to keep their children home and receive virtual instruction,” he said at a news conference Wednesday. “We must give parents the choice. This is the only thing that we’re asking these districts to do today — to the give the parents the choice.”

McMaster said “children have dropped off the radar” and “lost valuable learning progress” due to school closures.

“We must have our schools available,” he stressed. “Each district must allow the parents to make that choice.”

Districts must submit their reopening plans by July 17. Districts are asked to consider Sept. 8 as the start date.

McMaster’s announcement comes days after Education Secretary Betsy DeVos demanded that schools reopen in-person full-time.

12:50 p.m.: Oklahoma governor tests positive for COVID-19

Oklahoma Gov. Kevin Stitt has tested positive for COVID-19, he said during a video news conference Wednesday.

Stitt said he feels achy, but OK. His wife and children have tested negative.

Officials are now working on tracing those who may have come within 6 feet of the governor.

Stitt said at the news conference he is “not thinking about a mask mandate at all.”

“I’m hesitant to mandate something that is problematic to enforce,” he said.

The White House said in a statement that the president wishes Stitt a speedy recovery.

Stitt was among the attendees at President Donald Trump’s June rally in Tulsa.

Tulsa City-County Health Department Director Dr. Bruce Dart said last week that the rally, along with protests, likely contributed to the area’s surge in cases.

Over 21,000 people in Oklahoma have been diagnosed with COVID-19.

Philadelphia School District Superintendent William Hite Jr. called Education Secretary Betsy DeVos’ demand that schools reopen in-person full-time, “silly talk.”

“It’s a group that’s trying to give guidance that is completely out of touch. And it’s a group that up to this point hasn’t provided much guidance at all,” Hite said Wednesday. “We’re gonna be guided by health and safety. Not politics, not ideology.”

Philadelphia has over 27,000 cases of the coronavirus. The city’s positivity rate stands at about 5%.

Nationally, the overall test-positivity rate is 9.5%.

People under the age of 30 have accounted for 40% of new cases in Philadelphia, Mayor Jim Kenney said Tuesday, as he announced that large public events will be banned through Feb. 28, 2021.

5:59 a.m.: San Antonio hospitals have started using refrigerated trucks for bodies, officials say

San Antonio Mayor Ron Nirenberg and Bexar County Judge Nelson Wolff updated the community about the local response to COVID-19 in their daily briefing on Tuesday night and reported that there have been 21,067 total COVID-19 cases and 201 total deaths in Bexar County as of Tuesday, an increase of 854 new cases.

City officials also reported that 1,237 patients are currently hospitalized and that 417 are in the intensive care unit with a total of 260 on ventilators.

There are 11% of staffed beds available and 44% of ventilators available and Nirenberg said nearly 30% of those hospitalized with COVID-19 in the area had no underlying conditions.

Dr. Colleen Bridger, interim director of the Metropolitan Health District and assistant city manager, said there is a plan in place for when hospitals can ask for refrigerated trucks to hold bodies that can no longer fit in their morgues. She said the trucks are already in use in the area by facilities, but she did not specify how many or where they were being used.

Dr. Bryan Alsip, with University Health System, said most hospitals don’t have large morgues, so the refrigerated trucks are needed to handle any overflow of bodies. He said University Hospital may need the trucks.

Judge Wolff also took a moment to discuss the number of violations within Bexar County.

Wolff said there have been almost 130 violations of the local orders and that 62 of those violations were related to businesses not following the orders, with 67 of them related to gatherings. Only nine businesses have received written citations.

“We’ll be citing a lot more, I’m sure,” he said. Nirenberg said the city and county are doing proactive inspections to look for possible violations and are investigating calls from tipsters.

3:24 a.m.: Nashville Mayor: ‘We are headed in a terrible direction’

After the city of Nashville, Tennessee, hit a new record of 771 COVID-19 cases in a 24 hour period, the mayor of Nashville, John Cooper, was in no mood to mince his words.

“We are headed in a terrible direction and we’ve got to reverse that direction right now,” Nashville Mayor John Cooper said. “We’re not targeting people, but if people are persistently non-compliant after they have been asked to keep each other safe they will get a ticket,” Mayor Cooper said. “And we have to do that because we’re at 771 cases.”

Cooper also formally announced that anybody found to not wear a face mask in public would be ticketed and that a full-scale lockdown is not off the table.

“We’re at the point in the disease that unless we take this very seriously, we will have to have lockdowns that really seem intolerable, but needed to keep our hospitals functioning,” said Cooper.

Nashville will remain in it’s modified Phase 2 and bars will remain closed until at least August 1.

Said Cooper: “None of us would have believed we would have wandered into a bad science fiction movie, but we have. Frankly, I’m here today to tell you Nashville is back into another tornado situation where everybody has to have each other’s back and work together to work through this crisis.”

1:34 a.m.: Philadelphia Eagles fans won’t be allowed to attend home games this season, per city officials

The Philadelphia Eagles will be playing their home games without a home crowd this season, according to a Philadelphia city official.

“I do think that games can be played with the kind of safety precautions that they’re proposing. I do not think that they can have spectators at those games. There’s no way for them to be safe having a crowd there,” said Health Commissioner Thomas Farley on Tuesday. “I can’t say what the plans are for the league, but from a safety perspective, they can play games but not [have] crowds.”

According to the Philadelphia Inquirer, the city government has been in communication with the Eagles, said Managing Director Brian Abernathy, and has “told them our expectations are that they don’t have fans.”

The Philadelphia Phillies had already announced earlier this week that they would not be playing in front of a home crowd either and would pipe in fake crowd noise, use cardboard cutouts of fans and that the team’s mascot, the Phillie Phanatic, would practice social distancing while roaming the ballpark.

“Although we won’t be together physically, we look forward to uniting our community virtually with the goal of taking action for autism,” the Philadelphia Eagles said in a statement. “Please be assured that while the event will be virtual, we are working diligently to create an incredible experience for participants.”

1:02 a.m.: 36 high school students test positive for COVID-19 at sports camps in Illinois

In the past week, 36 cases of COVID-19 have been identified in a group of Lake Zurich High School students in Illinois who were part of athletic camps.

The cases have been tied to social events before the camps even started, and the positive test results among young people are part of an overall trend Lake County, Illinois, health officials have seen in the last month.

“We are grateful to the leadership of Lake Zurich District 95 for assuring proper health screenings were done at their athletic camps last week, because those measures helped identify this cluster of COVID-19 cases,” said Dr. Sana Ahmed, Medical Epidemiologist at the Lake County Health Department. “We continue to urge anyone who has COVID-19 symptoms or who may have had direct contact with a confirmed case to get a viral COVID-19 test (also known as a polymerase chain reaction or PCR test) and self-quarantine for 14 days from their last potential date of exposure. We need your help to help prevent further spread of this virus.”

The students are now in self-quarantine and health officials said positive cases among residents under the age of 30 are now higher than the general population.

“Our message to young people is that while you might not be at high risk of getting severely ill from COVID-19, you’re not immune,” said Hanna Goering, communications manager for the Lake County Health Department.

According to the Lake County Health Department, COVID-19 cases and deaths in Lake County had previously slowed in recent weeks, a trend that public health officials attribute to residents following social distancing and masking guidelines, paired with widespread availability of testing and thorough contact tracing. However, new cases continue to be identified in communities across the county, and an increase in social gatherings could result in cases climbing again.

“Our lives are very interconnected and this virus spreads very easily from person to person,” said Dr. Ahmed. “Even if you personally aren’t at a high risk of severe illness, you need to consider that every person you interact with may have someone close to them who is vulnerable. Please, do your part to protect your health and also look out for others. Take the risks seriously so your actions don’t result in someone else’s hospitalization or death.”
