Tracking UK Covid maps ( https://coronavirus-staging.data.gov.uk/details/interactive-map) to White Rose University areas from 3 weeks prior to term offers a striking visual correlation to the renewed outbreak.

Interesting comparator (rough, obvs) below: Cambridge, where classes stayed online.

U of Leeds weeks -2 to 1:

U of Leeds weeks 1-4:

U of Sheffield weeks -2 to 1:

U of Sheffield weeks 2 to 5:

Cambridge, weeks -2 to 1

Cambridge, weeks 2 and 3

This thread from yesterday shows interesting data/time comparisons as well. Seems the 15-24 year-old bracket was ahead of the renewed outbreak curve in many UK university cities.

Does this suggest that universities helped aggravate regional 2nd waves? https://twitter.com/danielhowdon/status/1321167694692032514?s=20
