The shifts in demographics have been recorded in parts of Florida, South Carolina, Georgia, Texas and other states — many of which were some of the first to reopen.
And while some officials have pointed to more widespread testing being done, others say the new cases stem from Americans failing to social distance.
Despite stark warnings from experts across the US, hundreds gathered Saturday in Tulsa, Oklahoma, for President Donald Trump’s first re-election campaign rally since the start of the pandemic.
Few donned masks even as Tulsa County reported its highest number of new infections in a day Saturday — the fifth time this week the country reported a record.
Where young people are testing positive
Those younger groups testing positive are mostly asymptomatic and don’t require clinical attention, the governor said.
“We’re also seeing that not only are they testing positive because they’re testing more, they’re also testing positive at a higher rate increasingly over the last week,” DeSantis said, adding there’s evidence of transmission between those younger groups.
That increased testing, he said, comes as many people are returning to the workforce.
In South Carolina, health officials said Friday people under the age of 30 were increasingly testing positive for the virus — around 18% of the state’s total cases come from people between the ages of 21 and 30.
“It’s a little bit of a disturbing trend, and what frightens me is not only that they are younger, the potential of them infecting other people, particularly parents and grandparents,” Chief Medical Officer at Grady Health System Dr. Robert Jansen told the news station.
Less than 7% social distancing in one Texas county
And the age of the people testing positive is trending younger, he told the news station.
“Our average age last week of people that were positive was age 30, the average age of people getting tested was 47,” he said.
And those numbers come as many haven’t followed guidance issued by health officials urging residents to keep their distance and wear face coverings.
“We have data from some of the cell phone companies that show in Galveston County less than 7% of the people are social distancing,” Keiser said.
Nearly half of states see rise in new cases
According to data from Johns Hopkins University, at least 23 states are trending upward in new cases compared to last week. Ten of those states reported more than a 50% jump — including Texas and Florida, which were some of the first states to begin reopening.
California, the first state to enforce sweeping lockdown measures, is also seeing an increase in cases.
As some states report record numbers of daily new cases and state leaders mull implementing face mask requirements, the World Health Organization warned the pandemic is accelerating.
More than 150,000 new cases of the virus were reported to WHO Thursday, the organization’s director-general, Tedros Adhanom Ghebreyesus said in a Friday news conference.
Almost half of those cases were reported from the Americas, he said.
“The world is in a new and dangerous phase. Many people are understandably fed up with being at home. Countries are understandably eager to open up their societies and economies. But the virus is spreading fast, it is still deadly, and most people are still susceptible,” he said.
