(NEW YORK) — A pandemic of the novel coronavirus has now killed more than 679,000 people worldwide.Over 17.8 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 national governments are hiding or downplaying the scope of their outbreaks.Since the first cases were detected in China in December, the United States has become the worst-affected country, with more than 4.6 million diagnosed cases and at least 154,744 deaths.Latest headlines:– If you go on vacation in a hot spot, ‘assume you’re infected,’ Birx says- Florida’s daily test-positivity rate falls below 10%Here’s how the news is developing today.

I saw all of America moving.””I think it’s our job, as public health officials, to be able to get a message to each American that says if you have chosen to go on vacation into a hot spot, you really need to come back and protect those with comorbidities and assume you’re infected,” Birx said.Birx said the current stage of the pandemic “is different from March and April.””It is extraordinarily widespread … it’s both rural and urban,” Birx said.”More importantly, if you’re in multigenerational households, and there’s an outbreak in your rural area or in your city, you need to really consider wearing a mask at home, assuming that you’re positive, if you have individuals in your households with comorbidities,” she advised.11:26 a.m.: Florida’s daily test-positivity rate falls below 10%In hard-hit Florida, the Department of Health reported a daily test-positivity rate of 9.28% on Sunday — the first time the daily test-positivity rate fell below 10% in several weeks.As of Sunday, just 19.24% of Florida’s adult ICU beds are available, according to the state Agency for Healthcare Administration.Forty-two hospitals have no available ICU beds, while 30 hospitals have just one remaining ICU bed, the agency said.These numbers are expected to fluctuate throughout the day as hospitals and medical centers provide updates.More than 487,000 people across the state have been diagnosed with COVID-19. Florida is the second highest state for number of cases, behind California.10:35 a.m.: Australia’s Victoria enters ‘State of Disaster’Australia had largely avoided widespread community transmission, but cases have been increasing exponentially in Victoria.

The team expects the complete results of saliva testing later Saturday, MLB said.In addition to Saturday’s game, both games of Sunday’s doubleheader between the teams have also been postponed.”Due to additional testing and monitoring of the St. Louis Cardinals’ players and staff members, the Sunday doubleheader between the host Milwaukee Brewers and the Cardinals at Miller Park has been postponed,” said Major League Baseball in a statement. The Cardinals will play four games against the Tigers in Detroit from Tuesday-Thursday, including a Wednesday doubleheader. The Cardinals and Tigers will serve as the home Club for two games each at Comerica Park. The Brewers will play this week’s home-and-home series vs. the Chicago White Sox as scheduled. Major League Baseball will continue to provide updates regarding its schedule.”Just last week multiple members of the Miami Marlins tested positive for the coronavirus causing games to be postponed.as coronavirus testing is underway, the league confirmed in a statement.The Miami Marlins canceled their home opener against the Baltimore Orioles scheduled for last Monday after multiple members of the team tested positive for the coronavirus,Since the Philadelphia Phillies played Miami one week ago at Citizens Bank Park, the Marlins have now had 20 positive tests, including 18 players.MLB commissioner Rob Manfred told MLB Players Association executive director Tony Clark on Friday that if the sport doesn’t do a better job of managing the coronavirus, it could shut down for the season, sources familiar with the conversation told ESPN.The two positive tests by the St. Louis Cardinals players on Friday have only exacerbated concerns inside the sport about the presence of the coronavirus and whether players are following MLB’s protocols are being followed properly to prevent outbreaks similar to Miami’s.Should another outbreak materialize, Manfred, who has the power to shut the season down, could move in that direction. Multiple players briefed on the call fear that season could be shut down as soon as Monday if positive tests jump or if players continue not to strictly abide by the league’s protocols.ABC News’ Alex Faul, Matt Foster, Ahmad Hemingway, Josh Hoyos, Christine Theodorou and Scott Withers contributed to this report.Copyright © 2020, ABC Audio.
