An internal Centers for Disease Control and Prevention document obtained by several news outlets warns that the COVID-19 delta variant could be more likely to produce severe illness and can spread as fast as chickenpox. The paper reported that the CDC document says health officials need to acknowledge the "war has changed."

John Moore, a virologist at Weill Cornell Medicine, told the Times that Delta "is the troubling variant we already knew it was."
