A novel coronavirus pandemic has now killed more than 520,000 people worldwide.
More than 10.8 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 the scope of their nations' outbreaks.
Since the first cases were detected in China in December, the United States has become the worst-affected country, with more than 2.7 million diagnosed cases and at least 128,740 deaths.

Seven-time NASCAR Cup Champ Jimmie Johnson, currently 12th in points, has become the sport's first driver to test positive.
Johnson, who said he planned to retire after the current season, will miss this weekend's race in Indianapolis.
He can return to the track after he's symptom free and has two negative COVID-19 test results at least 24 hours apart, according to NASCAR.
"Jimmie is a true battle-tested champion, and we wish him well in his recovery," NASCAR said in a statement. "NASCAR has granted Jimmie a playoff waiver, and we look forward to his return as he races for an eighth NASCAR Cup Series championship."
The World Health Organization said it expects interim results on a potential coronavirus treatment drug -- not a vaccine -- within two weeks.
"The group reviewed data from the solidarity trial and agreed on the need for more trials to test different classes of therapeutics at different stages of the disease," WHO Director General Dr. Tedros Adhanom Ghebreyesus said at a news conference Friday, adding that nearly 5,500 patients in 39 countries have been recruited for what's been dubbed the "solidarity trial."
"We expect interim result within the next two weeks," Ghebreyesus added.
The solidarity trial began as a study of five drug candidates, including the Trump-touted hydroxychloroquine, on which testing was halted after no significant coronavirus-related benefited were discovered.
The head of the WHO's Emergencies Program, Dr. Mike Ryan, said it would be "unwise at this point to predict when a vaccine could be rolled out."
"Vaccines may have shown efficacy by the end of the year," he added, "the question will be whether or not the scale of the production of those vaccines will be enough for us to begin vaccinating people early in 2021."
The Major League Baseball League and its Player's Association announced on Friday the results of their first round of mandatory COVID-19 testing.

As New Jersey's coast is inundated with sun-seekers this holiday weekend, officials are imploring residents and visitors to wear masks.
Ocean City Mayor Jay Gillian said city officials plan to roam the boardwalk on Saturday evening, awarding prizes at random to families and individuals who are wearing masks, The Associated Press reported.
The large crowds and gatherings that are expected at the beaches as the nation celebrates Independence Day have health officials on high alert. Moreover, New Jersey's casinos, amusement rides, water parks and restaurants have also reopened -- though with some capacity restrictions.
"We are especially concerned after the gatherings we saw at the Jersey Shore," the state's health commissioner, Judith Persichilli, told the AP. "Individuals were packed together, which raises the risk of spreading the virus."
Almost all new COVID-19 cases in Louisiana -- 98% -- are because of community spread, the state's health department reported.
About half -- 43% -- are among people under 29 and younger.
There have been an additional 1,756 new cases of COVID-19 since Thursday.
The new cases come as Gov. John Bel Edwards and New Orleans Pelican player Zion Williamson released a PSA encouraging residents to wear a mask or face covering while in public.
"It's up to all of us to do our part, and the three best and easiest things we can do to significantly reduce the spread of the coronavirus is to wear a mask when in public, practice social distancing and wash our hands frequently," Edwards said. "As we head into this holiday weekend it is critical that we not forget or ease up on the mitigation efforts we know work. Together, being good neighbors to one another, we will slow the spread and save lives."
"We still have a lot of work to do in order to slow the spread of COVID-19 in Louisiana," Williamson said. "Wear your mask and stay safe."
Louisiana only requires employees in open businesses -- not patrons -- to wear masks, according to Masks4All, an organization that promotes mask wearing.

A senior official who spoke on the condition of anonymity, said, "I hope it's reflected that these trips have been an important way for the Task Force to get ground reports from states, provide states what they need when they need it, and to assure the American people that we'll get through this together."

"I wish we could have done it sooner -- we acted on it as quickly as possible," Bethune said.

He died 10 days later.
Even as Republican-led states roll back reopenings due to the significant rise in coronavirus cases and warnings from his own government that the pandemic is far from over, President Donald Trump continues to take an optimistic tone about the increased in diagnosed COVID-19 cases.
"There is a rise in Coronavirus cases because our testing is so massive and so good, far bigger and better than any other country," Trump tweeted late Thursday night. "This is great news, but even better news is that death, and the death rate, is DOWN. Also, younger people, who get better much easier and faster!"
However, Adm. Brett Giroir, the man Trump appointed to oversee testing, testified at a House hearing Thursday that "this is a real increase in cases" and not just attributable to increased testing.
"There is no question that the more testing you get, the more you will uncover," Giroir said Thursday. "But we do believe this is a real increase in cases because of the percent positives are going up. So, this is real increases in cases."
Giroir said the U.S. is not flattening the curve. "The curve is still going up," he testified.

Varsity Tavern, located in downtown Tempe, allegedly permitted both employees and managers to continue working after being diagnosed, according to the State of Arizona Department of Liquor Licenses and Control.

The Department of Liquor also alleges that the bar management knowingly didn't notify health officials that workers tested positive, didn't enforce social distancing requirements and didn't enforce mask-wearing requirements.
