Philadelphia has reinstated a mask mandate for students and teachers on Monday (May 23), in its latest move to rein in COVID-19.
The news was announced Friday (May 20) by William Hite, superintendent of the public school district, who said it would remain in effect until further notice. “As we’ve learned since the pandemic began, the coronavirus continues to evolve and so too will our response to it,” Hite said in a statement.
Meanwhile, the WHO chief Tedros Adhanom Ghebreyesus warned Sunday (May 22) that the pandemic is “most certainly not over,” as he reminded governments that “we lower our guard at our peril.”
Ghebreyesus told officials gathered in Geneva for opening of the WHO’s annual meeting that “declining testing and sequencing means we are blinding ourselves to the evolution of the virus.”
