Here are some significant developments:
- Herman Cain, a former pizza chain executive and Republican presidential candidate, died after testing positive for the coronavirus. Though it is unclear where Cain contracted the disease, he attended a June Trump campaign rally in Tulsa that drew several thousand supporters, most of whom did not wear masks.
- President Trump visited the American Red Cross headquarters on Thursday and urged people who have recovered from covid-19 to donate their plasma to help others fight the disease the virus causes. He also wore a face mask as he toured the facilities in Washington, the third time he has worn one in public.
- Baseball’s Philadelphia Phillies announced that two staff members tested positive for the coronavirus. No Phillies players have tested positive, but the team’s three-game series this weekend against the Toronto Blue Jays has been postponed, and all activity at Citizens Bank Park has been canceled.
- Children may have as much of the coronavirus in their respiratory systems as adults, a new study says, complicating Trump’s assertion that children are safer from the virus than older people.
- About 1 in 5 U.S. adults packed up and moved because of the pandemic — or they know someone who did, according to a new survey by the Pew Research Center. The likelihood of someone moving or knowing someone who moved is greatest with higher levels of education and income.
