You asked
I would like population data set on all Covid19 tests, split as positive and negative. I would like the number of people in each group who have been tested and have had a positive test result in the past (more than 90 days) and recovered from symptoms. So population sample may be either filtered to dates after October 2020 or further analysed by month in which the later tests were done.

Thank you for your interest in the Covid-19 Infection Survey.
We hold the number of people per fortnight testing positive and the number of tests undertaken. This can be found in tab 1d in the data tables of the weekly bulletin.
In order to provide the rest of the data requested, we would need to create bespoke analysis. Under the Freedom of Information Act 2000, Public Authorities are not obligated to create information in order to respond to requests. We therefore consider this to be information not held.
If you wish to access the microdata for this survey, you will need to become an accredited researcher with the Secure Research Service (SRS). Details of which can be found in the link below. https://www.ons.gov.uk/aboutus/whatwedo/statistics/requestingstatistics/approvedresearcherscheme#research-project-accreditation.
Once you have become an accredited researcher, you can make a project application to access the microdata.
