In its weekly epidemiological update, the agency said the immune-escape data is based on preliminary lab-based studies and not on research in humans. The global case tally fell 9%, to 2.9 million new cases, in the week through Jan. 8, although with testing and delays in reporting from some countries result due to the end-of-year holidays, those numbers should be treated with caution, said the WHO.In the U.S., the seven-day average of new cases stood at 63,088 on Wednesday, according to a New York Times tracker. That’s down 2% from two weeks ago and below the recent peak of 70,508 on Christmas Eve.
