We are watching this carefully, and another in a regular series of charts from Dave Dixon on hospitalizations in the younger age groups. You can see that Delta is having little to no impact. Very low absolute numbers. No change in children. Young adults had an uptick in ICU use, but could be random. I would also note that the American Academy of Pediatricians, which has been terrorist in recommending masks and other nonsense, has issued a statement saying that they see no evidence of Delta causing more serious disease in children.
