Aha! They moved the landing pages that week, hence me clicking on the wrong report before.
I think the numbers are those detected in one week.
Could someone check?
The text ahead of the graphs is also useful
“ The following figures present population data based on the first time that individuals tested positive for SARS-CoV-2 through PCR and/or lateral flow device testing in England together with those who have tested positive for SARS-CoV-2 through PCR and/or lateral flow testing with an interval of at least 90 days between two consecutive positive tests. To the end of week 27 in 2021 (to 4 July 2021) 23,105 possible reinfections have been identified, of which 66 have been confirmed by identification of genetically distinct specimens from each illness episode (see Table 1).
For a possible reinfection to be categorised as confirmed it requires sequencing of a specimen at each episode and for the later specimen to be genetically distinct from that sequenced from the earlier episode. Availability of such dual sequencing is currently very low for several reasons; sequencing was not widely undertaken early in the pandemic; LFD test results do not allow sequencing and some PCR samples have a low viral load where sequencing cannot be undertaken. To meet the definition of a probable reinfection requires sequencing at the later episode that identifies a variant that was not circulating at the time of the earlier episode. Further details on the methodology, as well as additional data on reinfections are available in the graph set published alongside this report.
It is important to consider reinfections in the context of first infections and there is a 90- day delay before people with a first infection can become eligible for reinfection.”
It sounds like it is going to be very difficult to get confirmed reinfections, so not sure how useful that data will be.
Although there could be some interesting data in the reinfections based on different initial or second strain.
If I have read this right, in the week to 4th July, 23,101 people tested positive for a second time, at least 90 days after their first test, by either LFT or PCR.
In the same week (although daily testing data goes out to 5th July) the total number of positives by either method was 4,307,618
So only 0.5% of all reported cases that week.
In theory, this figure should be moving up week on week right?
