Younger people mixing for Euro 2020 matches are thought to be one of the drivers for a spike in cases on the east coast, where rates are highest among the under 40s.

Infection rates in Gorleston South and Beach stand at 1134.8 per 100,000 - one of the highest in the country - prompting a ramping up of testing and mobile units deployed at multiple locations.

Great Yarmouth Borough Council leader Carl Smith thanked the public for its response, with hundreds of tests given out over the weekend - although he stressed the focus was still on the younger age group coming forward and getting both jabs.

Diane Steiner, Norfolk's deputy director of public health, said: “We'd like to thank everyone who has taken part in testing so far - whether that's through our current enhanced testing, or through regular weekly symptom-free testing, workplace testing and testing when people get symptoms - all of these help us to find cases and reduce the spread of the virus.

“The reason that we're doing this enhanced testing is because we've seen wider transmission within the community that isn't within contained settings.

"It's possible that some of this will have occurred due to people coming together to watch the football matches, as they did across the country.

"Our highest rates are in younger adults under the age of 40."

A similar intervention was deployed in the northern villages of Ormesby, Hemsby, and Winterton where uptake has so far been good, although testing units are still on site, and anyone who hasn’t yet had a test is encouraged to do so.

Across Great Yarmouth as a whole in the seven days up to July 25, 583 people tested positive for Covid, giving an overall rate per 100,000 of 758.

During the same period there were no deaths within 28 days of a positive test, although the numbers in hospital had doubled to 12.

However, a swathe of southern villages taking in Belton, Burgh Castle, Bradwell, Gorleston, Fritton, and St Olaves.

Of those Gorleston South and Beach is among the worst affected with 100 new cases up to July 20.
