No, I think the fact the number of cases is up, but the % of positives is flat, is a bad thing
No - it means we are testing more but the prevalence of infection in the community is the same. So the number of cases found is up, but not the % of the community that is infected.
If the % prevalence were going up steadily, that would be concerning. At the moment, it's been bobbling between a seven day average of 0.59% and 0.54% for the last 3 weeks.
Interestingly, the Covid Zoe app seems to have been steady at UK level for about 10 days now after a week or so of going up.
