The head of the Centers for Disease Control and Prevention pleaded with Americans to wear masks and stick with Covid-19 mitigation measures, warning of “impending doom” as cases, hospitalizations and deaths begin to rise again. Rochelle Walensky, speaking at a press briefing Monday, fought back tears as she outlined a series of warning signals and said she was frightened about a looming fourth wave of Covid cases. The seven-day average for new daily Covid-19 cases is now almost at 60,000, up 10% from the prior week. Hospitalizations are also up, to about 4,800 a day from 4,600 a week earlier. Deaths, a lagging indicator, have also started to rise again, she said. “I’m going to reflect on the recurring feeling I have of impending doom. We have so much to look forward to, so much promise and potential of where we are and so much reason for hope, but right now I’m scared,” she said.
