Why wider testing is critical to the public health response to COVID-19
The virus test is important for identifying who is currently infected, and therefore needs to be isolated and monitored in case their symptoms worsen and they require hospital treatment.
The antibody test will track the spread of the virus through the community, including people who do not show symptoms or who are mildly affected, as well as those who become ill. This test will enable public health authorities to assess the degree to which the population has acquired immunity against coronavirus – this will be a major factor in relaxing social distancing and other measures introduced to control its spread.
Data from the antibody tests will also be important in determining the degree of protection that people have after infection and the length of time for which protection lasts. This information is crucial for the rapid development of treatments and vaccines.
In addition to wider testing, the Wellcome Sanger Institute and other expert groups around the country will be working to map the spread of the coronavirus in the UK. Samples from confirmed cases of COVID-19 will be whole genome sequenced and analysed to work out how the virus is spreading. This will inform strategies to prevent further spread of the virus and help clinical care of patients.
Sir Jeremy Farrar, Director of Wellcome, said: "Widespread diagnostic testing during this pandemic is critical to controlling the spread of infection. This initiative is a substantial step forward in our ability to fight this disease that will save many lives.
"Alongside other difficult but necessary public health measures such as physical distancing, cancelling mass gatherings, and school closures, testing is a critically important part of the response.
"Wellcome is extremely grateful to the Office for Life Sciences, Thermo Fisher Scientific, QIAGEN, Amazon, Royal Mail, Boots and Randox for joining this important partnership, and is committed to supporting this initiative."
