The primary achievement of this consortium will be the generation of actionable data which when combined with epidemiological and clinical information has the potential to inform interventions and policy decisions during the current UK COVID-19 epidemic. This sequencing capacity will enable real time evaluation of novel treatments and non-pharmacological interventions on SARS-CoV-2 populations and spread, and provide information on introductions versus community transmission and outbreaks. It will also evaluate signals of changing transmissibility and virulence.In the longer term, the full integration of UK population level SARS-CoV-2 genomics data, with matching NHS electronic health records, patient outcomes, human genomics and metagenomics data has the potential to generate insights into susceptibility to COVID-19 disease. Finally, the substantial new nationwide capacity in sequencing infrastructure, informatics and personnel that will be built by COGUK will remain at the end of the COVID-19 pandemic as a significant asset for the NHS, UK-PHA, UKRI and UK Government.
