Britain now has the highest death toll in Europe, at more than 50,000, and the deepest economic contraction of any major advanced economy. Hancock said the country's research laboratories at Porton Down were trialling new saliva tests that do not need to go to a laboratory, so they can deliver faster results.
"There are new technologies coming on track which we are buying and testing now," he said. "We'll ramp it up certainly over the remainder of this year." New Zealand Prime Minister Jacinda Ardern has promised mass testing there after its first local COVID-19 case in 102 days.
Widespread testing is seen as one way to reopen the economy, which suffered a record 20% contraction in the second quarter and is expected to see unemployment soar when the government ends its huge job subsidy programme in October. "Hard times are here," finance minister Rishi Sunak said last week.
ENCOURAGEMENT
New approaches to testing that do not need to be processed in labs could also spur a re-evaluation of Britain's policy of requiring travellers from countries such as Spain and France to quarantine. London's Heathrow Airport said on Wednesday that a testing area was ready to open should Britain approve a rule change and allow two tests, one on arrival and one some days later, to cut the quarantine time for travellers from the current two weeks.
"The move to increase mass testing and use new techniques will support efforts to encourage people to resume aspects of daily living about which they may well be nervous," said Sian Griffiths, Emeritus Professor of Public Health at the Chinese University of Hong Kong.
"Receiving this information within a faster time period will enable further consideration to be given to testing in situations such as airports." For the current lab-based tests, Britain's government says it currently has a daily testing capacity of more than 335,000, although in August between 150,000 and 190,000 tests have actually been processed on any given day.
By comparison, Germany's testing lab association said on Tuesday the country had been using about 750,000 of a weekly capacity of a million tests and so was using a higher proportion of its capacity. Cases in Britain have started to rise again, with more than 1,000 positive results on eight of the last 10 days.
The government said on Wednesday it would expand a testing study being run by the Office for National Statistics from 28,000 people now to 150,000 by October and ultimately to 400,000 to help establish a better national picture of the pandemic and spot local outbreaks.
