A pandemic of the novel coronavirus has now killed more than 355,000 people worldwide and at least 100,411 people in the United States.
Over 5.6 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 U.S. has become the worst-affected country, with more than 1.69 million diagnosed cases.

The number of COVID-19 patients in Louisiana hospitals has now dropped below 800 for the first time in two months, Gov. John Bel Edwards said Wednesday.
Over 38,000 people in Louisiana have been diagnosed with the coronavirus. At least 2,617 people have died.
Louisiana has 13 confirmed cases and one death connected to Multisystem Inflammatory Syndrome in Children (MIS-C), a dangerous coronavirus-related illness in children that's being reported in many states and countries.
The 13 young people range in age from 0 to 19, with a median age of 11, the governor said.
Eight have been discharged from hospitals, he said.
MIS-C has features like Kawasaki disease and Toxic-Shock Syndrome. Common symptoms include persistent fever, irritability or sluggishness, abdominal pain, diarrhea, vomiting, rash, conjunctivitis, enlarged lymph node on one side of the neck, red cracked lips or red tongue, swollen hands and feet.
1:54 p.m.: Amtrak is preparing to cut its workforce by up to 20%
Amtrak is preparing to reduce its workforce by up to 20%, citing the effects of the pandemic.
"Our ridership and revenue levels have been down 95% or more year-over-year since the pandemic began," CEO Bill Flynn wrote in a memo to employees.
The railroad company is projecting ridership levels in 2021 will be 50% of what it was in 2019.
Amtrak said the reduction is necessary to ensure they can "continue to make critical investments in our core and long-term growth strategies, while also keeping safety as our top priority."
"We are currently working to finalize a plan for achieving these workforce reductions in FY 2021 and have started the process of designing our go-forward structure," Flynn wrote.
"As we look ahead to FY 2021, it is clear we have no choice but to reduce our overhead structure to better align our costs with our revenues," Flynn wrote.
In a letter to Congress, Amtrak said it needs $1.4 billion in supplemental funding for the next fiscal year -- in addition to the $2.040 billion annual grant request the company submitted to Congress earlier this year. Amtrak received $1 billion through the CARES Act and the company has taken numerous cost-cutting measures to help offset revenue losses caused by the pandemic, including reducing schedules across its system.
12:22 p.m.: Data breach scam delays unemployment checks
At a time of record layoffs, a nationwide scam involving stolen personal information is delaying the payment of unemployment claims, the Massachusetts Executive Office of Labor and Workforce Development said Wednesday.
"Criminal enterprises" are using personal identification information stolen in prior data breaches to file "large amounts" of illegitimate claims through the Massachusetts Department of Unemployment Assistance, the office said.
The fraud has forced the Department of Unemployment Assistance to implement additional identify verification that will delay the payment for "many" unemployment claims in the state.
"Protecting the integrity of the unemployment system and ensuring benefits are going only to valid claimants is a top priority of the Department of Unemployment Assistance," said Labor and Workforce Development Secretary Rosalin Acosta. "While the program integrity measures we are taking will unfortunately mean that some claimants will experience temporary delays in payment, we believe these steps are necessary to respond to this unemployment scam."
11:40 a.m.: Disney World's phased reopening to begin with Magic and Animal Kingdom on July 11
Disney World's phased reopening will begin with Magic and Animal Kingdom on July 11 and Epcot and Hollywood Studios on July 15, said Jim McPhee, senior VP of operations at Disney.
Before July 11, there will be a soft opening for "select" guests as a way to test out the safety protocols.
Guests will also have to reserve their park tickets in advance.
Among the safety protocols in place are: temperature screenings; face covering requirements; limiting the number of people to improve physical distancing; and more plexiglass barriers where physical distancing cannot be maintained.
The Orange County Economic Recovery Task Force approved the plan Wednesday. Disney also needs to receive approval from Orange County Mayor Jerry Demings and Gov. Ron DeSantis.
Disney is the parent company of ABC News.
11 a.m.: Fauci says 'good chance' vaccine may 'be deployable by the end of the year'
Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, told CNN on Wednesday morning that he thinks "we have a good chance -- if all the things fall in the right place -- that we might have a vaccine that would be deployable by the end of the year."
Fauci underscored that the process to develop a vaccine is not a smooth one.
"There are a lot of landmines and hiccups that occur," Fauci told CNN.
He also emphasized that the rapid development of a vaccine could not come "at the expense of safety nor scientific integrity."

Nevada is ready to begin "phase two" of its reopening this Friday. Public and private gatherings can increase from no more than 10 people to a maximum of 50 people, while continuing to follow social distancing, Gov. Steve Sisolak announced Tuesday.
Gyms can reopen but at a maximum 50% capacity. Locker rooms must be closed and equipment must be set up to ensure 6 feet of social distancing.

Adult entertainment venues and nightclubs must remain closed.

But Las Vegas is best known for its casinos.
Sisolak said he feels "confident" that casinos can reopen on his June 4 target date. The Gaming Control Board is expected to issue a notice Wednesday with gaming operation requirements for the state, he said.

5:10 a.m.: South Korea reports spike in new cases
South Korea reported 40 new infections of the novel coronavirus on Wednesday, the largest daily increase in over a month.
A majority of the new cases were detected in Seoul, where a cluster of infections has been recently linked to reopened bars, nightclubs and other entertainment venues in the densely populated capital.
The last time the country's daily caseload was this high was April 8, when the South Korean Centers for Disease Control and Prevention reported 53 new cases of COVID-19.
South Korea now has a total of 11,265 confirmed cases with 269 deaths.
The country once had the largest novel coronavirus outbreak outside China, where the virus first emerged, but appears to have brought it largely under control with an extensive "trace, test and treat" strategy. The number of new cases reported there has generally stayed low, but health authorities remain wary of cluster infections and imported cases.
Starting Wednesday, South Korea is requiring airplane passengers to wear face masks on all domestic and international flights as part of efforts to slow the spread of the virus while public activities increase. People must also wear masks when using the country's public transportation and taxis.

3:32 a.m.: COVID-19 cases among US health care workers top 62,000
More than 62,000 doctors, nurses and other health care professionals in the United States have contracted the novel coronavirus and at least 291 have died, according to data released Tuesday by the Centers for Disease Control and Prevention.
The true numbers may be much higher, as less than a quarter of the more than 1.3 million people whose data the CDC analyzed disclosed whether they worked in the health care industry. Moreover, out of the estimated 62,344 cases of COVID-19 among health care personnel in the country, death status was only available for about 57%.
The number of reported COVID-19 cases in the profession was at 9,282 just six weeks ago. At that time, the median age of infected workers was 42 and nearly three-quarters were women.
Although most weren't hospitalized for the disease, severe outcomes -- including death -- were reported among all age groups. That information was not made available in the CDC's latest report.
