UKHSA data dashboard

In response to user feedback, we are testing alternative ways of presenting the monthly data sets (https://www.gov.uk/government/collections/healthcare-associated-infections-hcai-statistics#hcai-monthly-data-sets) as visualisations on the UKHSA data dashboard (https://ukhsa-dashboard.data.gov.uk/). The current data sets will continue to be published as normal and users will be consulted prior to any significant changes. We encourage users to review and provide feedback (https://forms.office.com/pages/responsepage.aspx?id=mRRO7jVKLkutR188-d6GZq_omTjl2IJDvzbYQeMv1vtUNTVVQlRNUDJISEQ3ODRNNzNNTFhGRkxBSi4u&route=shorturl) on the new dashboard content.
