The latest number of Delta variant cases in Wiltshire has been revealed.

As of July 7, a total of 715 cases linked to the new strain have been recorded across the county, according to data from Public Health England.

This time last week the figure was 394.

However, the body's updated Variant Technical Briefing published today shows the likelihood of infection amongst household contacts is falling.

The briefing says secondary attack rates (the likelihood of an infection occurring in a given context) amongst household contacts of cases with Delta is estimated at 10.3% for exposure events in the week starting June 7.

Despite this continued fall, secondary attack rates for both household and non-household contacts of cases with Delta remain higher than for the Alpha variant.

One expert also comments that the increase in cases is not translating to an increase in hospitalisations and deaths.

Dr Jenny Harries, Chief Executive of the UK Health Security Agency said: “The data continues to show that the sharp increase in cases that we are seeing is not being followed by a similar increase in hospitalisation and death.

"This is because two doses of the available vaccines offer a high level of protection against the Delta variant.

"Getting both jabs is the best way to ensure you and the people you love remain safe, so we once again urge everyone to come forward as soon as they are eligible.

“As we approach the planned end of restrictions, we must remain cautious and careful.

"Cases are rising across the country, and whilst the vaccines offer excellent protection, they do not offer 100% protection.

"Be sensible, and follow “hands, face, space, fresh air” at all times and make sure to get tested if required.”

Last week, Wiltshire's public health director urged people to "think twice" and continue to be cautious.

Asymptomatic people should take up the offer of twice weekly lateral flow testing and everyone should come forward for both jabs, Kate Blackburn said.

Public Health England said that the Delta variant currently accounts for approximately 99% of Covid cases in the UK.

It is responsible for the rapid rise in infections across the country and the delay to stage 4 of the Government's roadmap.
