NHS’ COVID contact tracing service started today–but where’s the app? Australia? (with comments)

To paraphrase the burger chain Wendy’s long-past spokeswoman, Clara Peller, ‘Where’s The App?’. The NHS debuted a contact tracing scheme for COVID, but it is a manual system dependent upon–people. If you test positive for the virus, you will receive a call from the NHS’ test and trace system. The person will ask for information about your recent contacts with others, and then asked to self-isolate for 14 days. Those names you provide will be contacted as well.

The NHSX-developed Bluetooth LE app remains in beta test on the Isle of Wight, which started on 5 May [TTA 5 May]. Reportedly there were 52,000 downloads in week one, which for an island with only 80,000 households is pretty impressive. 

The original rollout date set by Health Secretary Matt Hancock and NHSX chief Matthew Gould to the House of Commons’ science committee was mid-May, which has come and gone. The new date is now sometime in June. However, Baroness Dido Harding, the new director of NHS’s Test and Trace program, would not confirm that date–as we’d say, tap dancing quite hard.

The US has been hiring contact tracers by state from Alaska to New York. A recent study in preprint in MedRxiv (PDF) by Farzid Mostashari of ACO management company Aledade and others found that in order to reduce the transmission rate by 10 percent, a contact tracing team would have to detect at least half of new symptomatic cases, and reach at least half the people with whom they were in close contact.

Apps have been deployed in Australia (COVIDSafe) and Singapore (TraceTogether) and are in development in Switzerland and Germany. Most use BTE, but South Korea, India, Iceland, and some US states including North Dakota and Utah are using GPS phone location. China has been the most ruthless in using GPS data to monitor citizen locations and activity, to restrict their movements. Previously mentioned here [TTA 19 May] are UnitedHealth Group and Microsoft’s ProtectWell, PWC’s homegrown app–and Google and Apple announced in April a BTE app which hasn’t debuted yet. The Verge
