Can I just check what I am looking at on the tables above? Are the numbers total positives and the percentage the number of those positive that are delta, or are the numbers the number of Delta variant cases and a percentage of the total cases?
Eg Ipswich last two weeks says 5 cases, 50 percent Delta variant. Does that mean there were 10 cases altogether, of which 5 (50percent) were delta, or does it mean about 2.5 of those 5 positives were delta (I realise the figures don't quite work there!)
Thanks. Stockport has shot up by the looks of things.[/quote]
@WyldStallions
The numbers are
the numbers of delta variant cases picked up through standard surveillance
The percentage is
The number of delta cases picked up through standard surveillance for a two week period / the total number of cases that underwent surveillance testing for that two week period.
Taking your Ipswich example:
10 cases in total from the period 16th to 29th May were genome tested. This figure is not shown in the tables I posted.
5 of these were Delta to give the 50%.
The other 5 were all the Kent variant, again not shown on the table.
In total Ipswich had for specimen dates 16th to 29th May inclusive 19 cases in total. Again this figure not shown in the table.
I did think about showing total number of cases genome surveiiled, plus total overall cases but thought it might just become a blur of numbers. However I can add one or both in if people would find it useful to see.
The final thing to note is that the Sanger figures for w/e 29 May are likely not 100% complete.
In the download made available this morning Delta totals 4133 for w/e 22 May. In the file released last Monday the figure for w/e 22 May was 3867. So the w/e 22 May total has been increased by about 7%. I’d expect similar for 29 May in next week’s update. However I have not looked at how the extra 7% were distributed.
