Alerts on the NHS Covid-19 app informs users if they have been in close contact with a positive coronavirus case. If an individual is pinged by the app, they are advised to self-isolate for up to 10 days. In England 607,486 alerts were sent to app users in the period between 8 and 15 July, with a further 11,417 sent in Wales.

Another record then for the number of people pinged by the NHS Covid-19 app and sent into isolation.
For businesses struggling to deal with the impact on their employees this will be more evidence that a different approach is needed. The fact that the number of pings did not rise even more sharply in a week when case numbers were accelerating, may be an indication that some people have deleted the app, although we have to be cautious about extrapolating too much from one week's figures.
Its defenders point out that many of the complaints about the app concern wider health policy rather than the tech itself - the fact that people who may have been in contact with the virus are being told to isolate even if they are fully vaccinated is a policy applying to traditional Test and Trace too, and won't change until August 16th.
One man, who was heavily involved in the design of the app, told me people didn't realise that it worked on a number of levels - "even if someone ignores the message to self-isolate, telling them they have been exposed to the virus is likely to make them behave more cautiously."
He also said that while the anonymous nature of the app meant only limited data could be extracted from it, there was useful and early information for epidemiologists about the spread of the virus and the R rate.
The government still insists the app is doing the job for which it was designed - but there will be mounting pressure from industry for a more rapid change to allow people who are pinged to be tested rather than to isolate.
When the new Health Secretary Sajid Javid replaced Matt Hancock, there were reports that he wanted the app's sensitivity tweaked so that it sent out fewer alerts. But that appears to be off the agenda for the moment with the Department of Health insisting there are no immediate plans for any changes.
