The seven-day rolling average for daily new cases in the U.S. went from 66,294 on Oct. 25 to 108,736.7 on Sunday.In the past week, one of every 433 Americans was diagnosed with COVID-19, and hospitals in several states are running out of space and staff.Biden is moving forward with creating a coronavirus working group tasked with developing his administration's pandemic response.

He had filed a whistleblower complaint alleging he was reassigned to a lesser job because he resisted political pressure to allow widespread use of hydroxychloroquine, a malaria drug pushed by Trump as a COVID-19 treatment.Other members include Dr. Luciana Borio, who had senior leadership positions at the FDA and National Security Council during the Obama and Trump administrations; Dr. Ezekiel Emanuel, who served as a special adviser for health policy in the Obama administration; Dr. Atul Gawande, a senior adviser in the Department of Health and Human Services in the Clinton administration and medical writer; and Michael Osterholm, an epidemiologist who served as an adviser to Health and Human Services Secretary Tommy Thompson during the George W.
