Medics are warning people who have been double jabbed that there are five symptoms to look out for that might indicate a Covid infection.
A runny nose, headache, loss of smell, sneezing and a sore throat are the most common symptoms people with Covid have reported having in the past 30 days.
This is according to the latest data from the ZOE Symptom Study App, used by people to log their daily Covid symptoms.
Professor Tim Spector, lead scientist on the study, said: “Daily cases of Covid remain stubbornly high but it’s reassuring to see that unlike in previous waves, these rates aren’t yet translating into high numbers of hospitalisations and deaths.
“However, seeing what is happening with increasing deaths in Israel we need to be vigilant.
“Whilst vaccines have helped to reduce the severity of the disease, this stalling in cases suggests that we’re starting to see the protection provided by vaccines waning, meaning more fully vaccinated people could be infected in the future.
“With children in Scotland heading back to the classrooms this week, and cases starting to rise again there, we’ll be keeping a close eye on the numbers.”
Calls for change to NHS website
It comes as the NHS still only lists the original three Covid symptoms of a cough, fever and loss of taste or smell on it’s website.
If people are suffering from these symptoms, they must get a PCR test under official NHS guidance.
The new data has prompted calls for the list to be updated in a bid to encourage more people to get PCR tested.
‘Don’t delay your vaccine’
The UK’s vaccine programme has so far seen around three-quarters of adults in the UK double-jabbed.
Professor Chris Whitty tweeted: “The great majority of adults have been vaccinated.
“Four weeks working on a Covid ward makes stark the reality that the majority of our hospitalised Covid patients are unvaccinated and regret delaying. Some are very sick including young adults.
“Please don’t delay your vaccine.”
Almost 3 million young adults not had jab
New figures showed that 55% of people in hospital with the Delta variant – which is dominant in the UK – have not been jabbed.
The data from Public Health England (PHE) also shows that 74% of people under 50 in hospital with the variant had not been vaccinated.
Almost two thirds of people in the same age group who died in England with the Delta variant were not vaccinated against the virus, the figures show.
Nearly three million young adults have not had a first dose, according to figures published earlier this week by the four health agencies.
There has been a concerted effort to get as many people vaccinated as possible, with 16 and 17-year-olds getting letters and text reminders this week inviting them for a jab.
Public Health England data, published on August 20, showed there were 1,189 deaths up to August 15 of people who were either confirmed or likely to have had the Delta variant and who died within 28 days of a positive test.
While the majority of deaths with the variant were in people aged 50 or over, the under-50s account for more when it comes to hospital admissions.
Covid infection levels remain high across the UK and have risen in Wales and Northern Ireland, according to the latest estimates from the Office for National Statistics (ONS).
They are highest in Northern Ireland, with an estimate of one in 50 people in private households having the virus in the week to August 14 – the highest level since the week to January 23.
The estimate is one in 80 people in England, one in 130 in Wales and one in 200 in Scotland.
