New Sheffield university clinical trial aims to 'break the chain' of Covid-19 in hospitals

University College London will lead the trial, in partnership with scientists from the University of Sheffield, as part of the Government’s £20 million Covid-19 Genomics UK Consortium (COG-UK).
The pioneering study will evaluate the use of ‘real time’ viral genomic data to reduce the spread of coronavirus within hospitals.

The COG-UK has established a network of rapid genome sequencing centres across the UK, which enables scientists to map the virus’ spread across the country.
Dr Thushan de Silva, from the University of Sheffield’s Department of Infection, Immunity and Cardiovascular Disease said: "We hope that our ability to analyse viral sequencing data in real-time and map the virus' spread in this unique way will not only help reduce the risk of SARS-CoV-2 within hospitals, but also consolidate the routine use of pathogen genome sequencing within NHS service delivery.
"This pioneering study will provide vital evidence on the role of rapid viral genome sequencing in helping to reduce the spread of SARS-CoV-2 within hospitals.

The research is led by Professor Judith Breuer, Director of the University College London Hospital / Great Ormond Street Hospital Biomedical Research Centres funded Pathogen Genomics Unit, together with the UCL Comprehensive Clinical Trials Unit (CCTU).
Professor Breuer added: “Spread of COVID-19 infections in hospitals is now recognised to be a major problem for both healthcare workers and patients, and ‘breaking the chain’ of these transmissions is critical.
"Tried and tested procedures to minimise infection spread in hospitals are already in use, including separating COVID-19 infected patients from uninfected patients, extensive cleaning, the use of PPE, and continual hand washing.

The UK Government and National Institute of Health Research (NIHR) said the study – named the COG-UK Hospital Onset COVID-19 Infection (HOCI) trial – was of ‘Urgent Public Health’ importance.
The study, which involves over 15 hospitals linked to sequencing hubs across the UK, was developed in collaboration with Sheffield Teaching Hospitals NHS Foundation Trust, Imperial College Healthcare Trust and the Queen Elizabeth University Hospital Glasgow with the MRC-University of Glasgow Centre for Virus Research.
Each hub will analyse the COVID-19 sequences in nasal and throat samples from all known COVID-19 patients in the hospital, along with newly infected hospital patients and frontline NHS staff.

The genomic data is likely to enable clinical teams in each hospital to see if newly infected patients have picked up the virus from a known positive COVID-19 patient within or outside the hospital and help infections be better controlled.
