People are being urged to know there are more symptoms of Covid than just the classic three – the persistent cough, fever, and loss of sense of smell and/or taste. The ZOE COVID app, which is in collaboration with King’s College London and Guy’s and St Thomas’ Hospitals, has been monitoring symptoms since the start of the pandemic.
And in its latest update, study lead Tim Spector has warned people to look out for other symptoms.
He said: “The data from the ZOE COVID Study has shown that there are over 20 different symptoms of COVID-19, not just the classic three: fever, cough and anosmia.
“The COVID-19 situation in the UK is different to last summer due to new variants and the vaccine roll out.
“We’ve found that the symptoms in younger people and post-vaccination are both different.
“People urgently need to know there are more than just the three classic symptoms.
“The top symptoms being currently logged in the Zoe app are; headache, runny nose, sneezing, fatigue and sore throat, which for many will feel more like a common cold.”
Professor Spector continued: “The earlier people can catch the infection, the quicker they can self-isolate until symptoms abate and stop the spread.
“We encourage anyone feeling under the weather to take a test as soon as they can and stay at home.”
According to the ZOE COVID study’s latest figures, it’s estimated among unvaccinated people in the UK there are currently 15,099 new daily symptomatic cases of Covid on average, based on PCR test data from up to five days ago. This is an increase of 18 percent from 12,830 last week.
The data continues to show the positivity rate is much higher in those with just a first dose, compared to those who are double vaccinated.
According to the prevalence data by age, the number of cases in the 20-29 age group continues to rise, but cases in the age groups over 30 have begun to level off.
The data also shows a small proportion of those who have been vaccinated still get infected.
ZOE collected reports last week from 487 contributors who had on infection after two doses of the vaccine, and 284 who reported an infection after one dose.
The following approximate risk factors for infection based on one, two or zero doses of the vaccination, have been recorded using the latest ZOE data:
Current risk of new daily COVID infection
- in the unvaccinated: 1 in 1,664
- after 1 vaccine dose: 1 in 4,374
- after 2 vaccine doses : 1 in 13,506
But people who have received both vaccinations have been shown to have much greater protection against COVID-19.
Professor Spector said: “ZOE COVID Study data this week shows rates in former hotspots, such as Scotland and the North West of England, continuing to plateau.
“At the same time, top UK holiday destinations like Cornwall are emerging as new areas with rapidly increasing cases.
“I think this is down to a number of factors, including the sudden influx of holidaymakers over half term, as well as the recent G7 summit and a previously unexposed local population.
“We need to remain vigilant of these UK holiday destinations as summer holidays approach, and ensure that we minimise outbreaks by following government guidelines.”
The Delta Cover variant is currently the dominant strain in the UK.
But nearly 40 cases of a newly identified variant have been detected in the UK, dubbed the ‘Delta plus’ variant.
