Between 8 – 15th July, more than 600,000 people using the NHS Covid-19 app in England and Wales have been sent self-isolation alerts.
Data represents 618,903 alerts were sent – a 17% increase from the last week.
However, it will still exempt some fully-vaccinated key workers from self-isolating if the app alerts them as close contact of a positive case.
Business secretary Kwasi Kwarteng shared with the BBC that a “very narrow” list of jobs would be shared today.
He added self-isolation for all fully-vaccinated people alerted by the app as close contacts are due to be brawled by 16 August.
The app alert is advice-giving only and not enforceable by law unless a phone call is received from the Test and Trace team.
Latest government figures display another 44,104 daily coronavirus cases in the UK, with 73 coronavirus-related deaths.
Prime Minister Boris Johnson cautioned cases could increase even more this week, as most legal restrictions have ended in England.
Alerts on the NHS Covid-19 app tells users if they have been in close interaction with a positive coronavirus case. If an individual is alerted by the app, they are instructed to self-isolate for up to 10 days.
In England, 607,486 alerts were sent to users between 8 and 15 July, with a further 11,417 sent in Wales. There were fewer app pings per case in England during this period, with 2.8 pings issued per every reported coronavirus case.
An average of 3.2 pings was sent per case reported in the last month.
