A pandemic of the novel coronavirus has now killed more than 682,000 people worldwide.
Over 17.7 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 154,320 deaths.
Here’s how the news developed on Saturday. All times Eastern.
9:03 p.m.: Texas governor to skip Republican National Convention
Texas Gov. Greg Abbott will skip the scaled-down Republican National Convention later this month in North Carolina as his state continues to fight a surge in COVID cases.
Abbott detailed his decision to GOP Chairwoman Ronna McDaniel in a letter obtained by ABC News.
“It was an honor being selected to serve as Chair of the Texas Delegation for the 2020 Republican National Convention,” Abbott wrote. “However, as we deal with the COVID-19 pandemic, my top priority remains focused on protecting the health and safety of Texans. As such, my duties as Governor will not permit me to attend the convention session in Charlotte, and specifically the 37(e) convention on Monday, August 24, 2020.”
Lt. Gov. Dan Patrick will instead represent Texas at the convention.
8:40 p.m.: Cardinals-Brewers doubleheader called off
MLB continues to struggle to get ahold of its COVID problem.
The doubleheader between the St. Louis Cardinals and Milwaukee Brewers scheduled for Sunday were the latest games to be postponed due to positive tests.
Saturday’s game between the two teams had already 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,” MLB said in a statement.
Three staff members and one player from the Cardinals have tested positive, according to ESPN.
The Cardinals are currently scheduled to return to action on Tuesday for a four-game series at the Detroit Tigers, including a Wednesday doubleheader. The Brewers are next scheduled to face the Chicago White Sox on Monday.
4:33 p.m.: South Africa surpasses 500,000 cases
There are now 503,290 confirmed cases of COVID-19 in South Africa, according to the country’s Department of Health.
There were 10,107 new cases reported and more than 3 million tests have been conducted, the agency said.
Deaths also increased, with 148 fatalities in the last 24 hours in the country of some 57 million. The total number of deaths is 8,153.
4:19 p.m.: FDA authorizes 1st tests that estimate patient’s antibodies
The U.S. Food and Drug Administration has authorized two new antibody tests capable of estimating the number of antibodies in a person’s blood.
The tests, called “semi-quantitative” tests, “may be useful as we continue to learn more about the virus and what the existence of antibodies may mean,” Tim Stenzel, director of the Office of In Vitro Diagnostics and Radiological Health at the FDA, said in a statement.
Scientists still do not know if, or to what extent, antibodies offer immunity to COVID-19.
“Patients should not interpret results as telling them they are immune, or have any level of immunity, from the virus,” Stenzel said.
3:54 p.m.: Phillies, Marlins to resume playing next week
The Philadelphia Phillies are set to resume playing Monday, after several games had been canceled “out of an abundance of caution,” according to the Major Leagues Baseball.
The games were canceled because the Phillies had played against the Miami Marlins, a team that experienced numerous COVID-19 positive tests among players and staff.
The MLB said the last exposure of Phillies players and staff was on July 26, and no players have tested positive since.
Three staff members did test positive, but MLB said it appeared two of those results were false positives.
The Miami Marlins also are scheduled to resume playing, Tuesday against the Baltimore Orioles.
The players and staff had been in quarantine in Philadelphia since July 26. The Marlins reported no new positive tests results in Friday’s collections, according to MLB.
3:20 p.m.: California reports highest daily deaths
The California Department of Public Health reported that 219 people died of COVID-19 in the last 24 hours, marking the state’s highest daily death toll.
The total number of fatalities is now 9,224, according to the agency. There were also 6,542 new cases, with the 14-day average reaching 8,912.
However, hospitalizations and ICU admittances are falling.
This week’s positivity rate — 6.5% — was nearly a full point below that of the previous 14 days, 7.3%.
Earlier in the day, a tally of total cases by Johns Hopkins showed that cases in the state surpassed 500,000. The California Department of Public Health confirmed that number.
1:20 p.m.: House Democrat tests positive after contact with Gohmert
Rep. Raul Grijalva, D-Ariz., the chairman of the House Natural Resources Committee, has tested positive for COVID-19.
Grijalva’s diagnosis comes days after he had close contact with Rep. Louie Gohmert, R-Texas, at a committee hearing. Gohmert, who refused to wear a mask, tested positive earlier this week. Gohmert recently said in the past few weeks he has worn a mask more.
Grijalva said he’s asymptomatic and will self-isolate.
“While I cannot blame anyone directly for this, this week has shown that there are some Members of Congress who fail to take this crisis seriously,” he said in a statement. “Numerous Republican members routinely strut around the Capitol without a mask to selfishly make a political statement at the expense of their colleagues, staff, and their families.”
In addition to Grijalva, three House Republicans and several GOP staffers also are self-quarantining after contact with Gohmert.
1:06 p.m.: Milwaukee Brewers player opts out for rest of season
Lorenzo Cain, an outfielder for the Milwaukee Brewers, has chosen not to play for the remainder of the season.
“We fully support Lorenzo’s decision, and we will miss his talents on the field and leadership in the clubhouse,” President and General Manager David Stearns said in a statement.
The news comes a day after the Brewers’ game against the St. Louis Cardinals was postponed.
Cain later issued a statement saying the decision was made after “careful consideration and discussion with my family.”
“With all of the uncertainty and unknowns surrounding our game at this time, I feel that this is the best decision for me, my wife, and our three kids,” he said, adding that the team was “very understanding and supportive.”
“I wish all of my great teammates the best of luck this season and look forward to getting back on the field in 2021. Please stay safe,” Cain said.

8:54 a.m.: Ohio State releases pledge students must sign to return to campus
The Ohio State University has released a pledge that all students who want to return to campus must sign as part of their effort to minimize the spread.
The pledge — called the Together as Buckeyes Pledge — mandates that students follow the university’s guidelines on social distancing, masks and hygiene tips.
It also reads, “I understand that COVID-19 is a highly contagious virus and it is possible to develop and contract the COVID-19 disease even if I follow all of the safety recommendations of the university and comply with the Pledge.”
Students cannot return to campus without having signed the pledge.
For those who don’t sign, they “would be failing to comply with a legitimate university directive and pursuant to university policies, students, faculty, and staff will be subject to the appropriate accountability measures and disciplinary actions,” the pledge reads.
Students will be contacted by the student conduct office and given five days to sign the pledge if they have not done so by the time school begins, according to The Columbus Dispatch. If a student still does not sign the pledge, he or she will only be permitted to take virtual courses, may not schedule a move-in time, may not physically enter any campus or university facility and may not physically participate in any university activity on or off campus, the Dispatch reported.

5:31 a.m.: Northeastern University to require all students be tested 3 times
Northeastern University announced Friday that it will require all students arriving at the Boston campus for the fall semester to be tested three times for COVID-19 and then immediately self-quarantine.
Students also must be tested two more times, on the third and fifth day after the first test. Those whose initial test comes back negative will be allowed to discontinue their quarantine. After the third test comes back negative, students will be allowed to fully participate in campus activities, such as going to classes, according to Northeastern University.
The new measures will apply to every student arriving on campus from all states for the start of the fall semester, whether they live on or off campus.
Students living on campus who test positive for the novel coronavirus will be isolated and moved into designated on-campus housing units with their own bathrooms. Food will be delivered to the students there, and case managers and clinical support will be made available on a daily basis, according to the university.
4:07 a.m.: US reports over 67,000 new cases as total tops 4.5 million
Just over 67,000 new cases of COVID-19 were identified in the United States on Friday, bringing the nationwide count soaring past 4.5 million, according to a count kept by Johns Hopkins University.
The latest daily caseload is under the country’s record set on July 16, when more than 77,000 new cases were identified in a 24-hour reporting period.
A total of 4,562,171 people in the United States have been diagnosed with COVID-19 since the pandemic began, and at least 153,314 of them have died, according to Johns Hopkins.
