The trial of a "check, monitor and trace" programme started on the Isle of Wight in early May. All 80,000 households on the island have been asked to download a smartphone app designed to shortly trace current contacts of anyone with the virus.
Within every week, the app had been downloaded about 55,000 occasions. If it's judged successful, a nationwide programme might be rolled out inside weeks. Hiring is now under way for an ''army'' of contact tracers, together with hundreds of name handlers.

What is going to contact tracing appear to be within the UK?
The government is on the brink of deploy a contact tracing group of three,000 civil servants and well being staff, and 15,000 name handlers. It has posted several job adverts for people who are unemployed and eager to help deal with the calls, topic to a two week training programme.
Their phone tracing shall be used alongside the smartphone app.
The free app tracks when customers come into contact with each other. As soon as downloaded, the app runs in the background of your telephone, offered Bluetooth is switched on.
If a consumer develops coronavirus signs, it is as much as them to let the app inform the NHS.
That message might trigger an nameless alert to users with whom they just lately had vital contact, probably asking these individuals to go into quarantine or be tested.
Why was the Isle of Wight chosen for the trial?
Health Secretary Matt Hancock says the aged population on the island - and estimated decrease number of smartphone users - was a factor. Whether it is successful despite these challenges then that may show it could possibly work throughout the UK.

Will contact tracing help finish lockdown?

South Korea never went into lockdown because of an early strategy of in depth tracing and mass testing. There was guide monitoring of credit card transactions, CCTV and cell phone tracking to piece together the place individuals had been.
The UK in all probability won't use that degree of tracking but a extensively used app would permit the federal government to ease some restrictions.
Take-up will have to be colossal for the virus to be totally supressed. Teachers advising the NHS estimate 80% of smartphone users - 60% of the inhabitants - must actively use it.
By comparability, about 67% of UK smartphone customers have downloaded messaging app WhatsApp.
The teachers' mannequin does not consider the over-70s, due to their average low smartphone usage, and the idea many can be shielding and so not coming in to contact with numerous other individuals.
Individuals would additionally need to be trustworthy about displaying any potential symptoms and inform the NHS.
What if I don't have a smartphone?
Only individuals with a smartphone can entry the app. As it launched the Isle of Wight trial, the federal government stated there can be an choice for individuals to report symptoms and order checks in other ways, together with over the telephone and by way of a web-based service.
Everyone who studies falling unwell, together with app users, might be asked to report current contacts both on-line or by way of phone - so the hope is that tracers can attain all those at attainable danger, not simply individuals with the app.

''Tens of millions of us are going to wish to belief the app and comply with the recommendation it offers,'' says NHSX, the know-how arm of the health service. It says the knowledge gathered will only ever be used for health and analysis functions, and that the app could be deleted at any time.
The UK app will use a "centralised mannequin", which means the matching process will happen on a computer server.
An alternate, decentralised model was put ahead by Apple and Google, the place the change occurs on individuals's handsets.
The tech giants say their version makes it more durable for hackers or the authorities to use the computer server logs to track and determine specific individuals.
But NHSX says its centralised system will help give it more perception into how the disease spreads and assist it to make the app extra environment friendly.
Mr Hancock stated the app will take "full consideration" of privateness considerations.
