Text: the analysis presented in this paper requires full access to personal identifiable information which we were able to perform, as public health england has health research authority approval to hold and analyse national surveillance data for public health purposes under section 251 of the nhs act 2006. this research informs and improves public health england's ability to conduce national surveillance data for public health purposes. unfortunately the public health datasets cannot be made publicly available, or anonymised in an appropriate manner using any of the methods suggested by uk data archive or other providers http://www.data-archive.ac.uk/create-manage/consent-ethics/anonymisation. qualified researchers wishing to access the data for verification purposes will need to do so within appropriate governance procedures including agreements with the data guardians (public health england), honorary contracts with public health england, and ethical and legal permissions for handling identifiable data for the specific research purpose proposed. the authors of the manuscript would be happy to help facilitate access to the data within these rules.<|eot_id|><|start_header_id|>assistant<|end_header_id|>
