More than 1,000 Islanders were 'pinged' by the NHS Covid-19 app in the week to July 28.

NHS figures show 1,356 people on the Isle of Wight were alerted over those seven days - fewer than the 1,776 pings sent out the week before.

It meant they were asked to isolate for up to 10 days, to help stop the spread of coronavirus, after being in close contact with someone who had tested positive.

Meanwhile, Department for Health and Social Care figures show official contact tracers told 838 people on the Island to self-isolate, in the week to July 28.

The scheme seeks out those who have been in close contact with someone with Covid-19, over the 48 hours since they first had symptoms.

The number of official Test and Trace contacts went down, from 842 people during the previous week.

Isolation is not mandatory for people “pinged” by the Covid app in England, but anyone who is contacted and told to self-isolate by NHS Test and Trace has a legal obligation to do so.

Some have urged continued caution, saying the falling numbers could be down to fewer people taking tests.

It comes alongside a fall in the number of check-ins to venues using the app.

On the Isle of Wight, there were 8,811 venue check-ins in the week to July 28.

That is 61 per cent fewer than the week before.

Meanwhile, the app is being updated so fewer contacts will be instructed to isolate.

Health and Social Care Secretary Sajid Javid said the “logic” behind the app is being tweaked, although the sensitivity and risk threshold will remain unchanged.

Instead of checking contacts for five days before a positive test, the app will only go back two days.

Mr Javid said: “We want to reduce the disruption that self-isolation can cause for people and businesses while ensuring we’re protecting those most at risk from this virus.”

“This update to the app will help ensure that we are striking the right balance.

“It’s so important that people isolate when asked to do so in order to stop the spread of the virus and protect their communities.”

The figures do not include those told to isolate in specific settings such as schools and prisons.
