BuDS have produced 141 weekly Covid-19 risk assessments using data from the Office for National Statistics (ONS) Covid-19 Infection Survey.

BuDS have carried out an options appraisal on what to do now, and have decided to continue to publish a short weekly risk assessment using the best available Covid-19 data. We will also publish a monthly Covid-19 bulletin with full weekly deaths, hospitalisations, and vaccinations data.
