COVID-19 live updates: Judge rules governor stop banning mask mandates in schools

More than 180,000 new COVID-19 cases were reported among kids last week, reaching levels of the previous winter surge of 2020-2021, according to a new report from the American Academy of Pediatrics and the Children’s Hospital Association.

More than 4.59 million children have tested positive for COVID-19 since the onset of the pandemic. Last week, children represented 22.4% of all reported cases.

Severe illness due to COVID-19 remains "uncommon" among children, the two organizations wrote in the report. In nearly two dozen states, 0.2%-1.9% of all child COVID-19 cases resulted in hospitalization.

AAP and CHA, however, warned that there is an urgent need to collect more data on the long-term consequences of the pandemic on children, "including ways the virus may harm the long-term physical health of infected children, as well as its emotional and mental health effects."

The Pentagon will move forward with making the Pfizer vaccine mandatory now that it has been fully approved by the FDA, Pentagon press secretary John Kirby said Monday.

Defense Secretary Lloyd Austin announced on Aug. 9 that he would seek authorization to mandate the vaccine for the military unless the FDA approved it before Sept. 15. 

“Now that the Pfizer vaccine has been approved, the department is prepared to issue updated guidance, requiring all service members to be vaccinated," Kirby said at a briefing. "A timeline for vaccination completion will be provided in the coming days."

All of New York City’s nearly 150,000 public school employees must receive at least one vaccine dose by Sept. 27, Mayor Bill de Blasio will announce Monday. The new vaccination policy will not allow weekly testing as an option.

At least 63% of New York City's Department of Education employees are already vaccinated, Schools Chancellor Meisha Porter said.

The previous requirement allowed for weekly testing of the unvaccinated, with unpaid suspensions for workers who didn't comply.

New York City's school year starts on Sept. 13.

The 79-year-old, who has Parkinson’s disease, was vaccinated for COVID-19 in January, WLS reported.

“She is having some oxygen but is able to function and breathe on her own without a respirator,” he told WLS.
