Just looking at the latest age breakdowns for reported cases - this just for England.
10-14s are the stand out of course, latest 7 day rate (up to 22nd Sep) past 1300 per 100,000. More than double that of the next highest.
5-9s continue on a shallower upward trajectory.
The first signs of an upward shift for 15-19s becoming clearer; although the rate of increase someway removed from that seen previously.
More likely parent of school DCs age groups showing an upward drift - 35-39s , 40-44s and 45-49s; and to a lesser extent 50-54s.
All the rest pretty flat, or still decreasing. Includes the 20-24s, who now have the second lowest rate of any age band under 60.
