Scotland seems to be avoiding the huge commercial success of the NHS Covid app in England, sending a large number of "pings " that tell people they need to be. 'isolate.
In just one week this month, England received 520,000 pings from the contact tracing application. Entire critical business teams are on leave.
More than a tenth of workers at Nissan's Sunderland plant are on leave. This affects the teams that operate the seaports.

Warehouse workers are wiped out. Existing difficulties with a great shortage of truck drivers, due to Brexit and a backlog of driving tests, are further compounded.
Businesses are forced to close, reduce teams or reduce opening hours . Goods are not picked up on time and deliveries are delayed. This may soon start to affect the fuel supply to gas stations.
The knock-on effect of disruptions in warehouses and supply chains is affecting the supply of goods to other parts of the UK, the food supply chain.fresh ts being the first to become obvious.
Yet the main problem with the contact tracing app - doing its job diligently, we have to assume, rather than just going rogue - n ' not affect Scotland to the same extent.
Why? I tried to find out.
Since its launch last September, the Protect Scotland app has received less than 60,000 "ping " notifications in total, which should affect those who are within two meters of an infected person for at least 15 minutes.
This could be explained by different infection patterns. And although Scotti sh infections have very recently declined while those in English are increasing, the patterns have not been so different that they might be the only explanation.
Another reason may be that the NHS England app is combined with a code scanner that people can register withtheir presence in a restaurant or pub. The Scottish app lacks that incentive to download it and keep it active.
Figures show around half of those who originally downloaded the Scottish app don't have it active anymore . There is no equivalent figure for the English application.

Asked when asking 'a press conference earlierThis week why there are far fewer app pings, Assistant Medical Director Nicola Steedman, Officer, explained that the software is more complex in English application, but no less responsive.
While the difference may reflect the decline in the number of infections in Scotland, she also suggested it had to do with those asked to enter a code to say they tested positive.
In England, if you book a Covid test through the app, any positive result will be automatically logged.
In Scotland, the person concerned must do so. It's anonymous, so there is no penalty for not doing it, but Dr Steedman called on people to help the test and protect the system by doing it.

He can explain how it works its system, but is not able to tell how English is different. It does confirm, however, that it is more complex than "deployed in the market elsewhere ".
