The signs of the brand new variant are barely completely different – stuffy nostril, sore throat – and since it can’t but be particularly recognized by dwelling take a look at kits, which merely inform us whether or not somebody is Covid-positive or unfavorable, not which pressure they’ve contracted.
Professor Tim Spector, from Britain’s ZOE Covid app, mentioned it’s now extra essential than ever to get examined – even with out signs – as we search to deliver the brand new variant underneath management in opposition to hovering an infection charges.
It comes as Dr Chaand Nagpaul, chairman of the council on the British Medical Affiliation, mentioned there was concern over a “vital enhance” of individuals in hospital with coronavirus.
Professor Spector mentioned that knowledge from the ZOE examine app means that about half of all instances of Delta are being “missed” as a result of individuals are solely looking out for the “traditional” Covid signs of fever, new and chronic cough and a loss or change of scent or style they’ve been advised to anticipate by the official steering, whereas a gentle case might not end in the entire situations on that guidelines being skilled.
“Omicron might be rather more much like the gentle variants we’re seeing in individuals who have been vaccinated [but still subsequently taken ill] with Delta than the rest,” he mentioned.
“And so it will be producing cold-like signs that individuals received’t recognise as Covid if they only consider the official authorities recommendation.”
Christina Marriott, chief govt of the Royal Society for Public Well being says: “Rising proof reveals that individuals who’ve acquired two doses of the vaccine sometimes current with much less extreme signs, akin to headache, runny nostril, sneezing, sore throat and lack of scent.

The ZOE Covid Symptom Research, funded by the federal government, has recognized the highest signs related to Covid and says they differ barely relying on whether or not you might have been vaccinated or not.
Headache
Though complications are a much less well-known symptom of Covid, they’re one of many earliest indicators, in accordance with the ZOE examine, and are extra frequent than the traditional signs of cough, fever and lack of scent.
The examine discovered Covid complications are typically reasonably to severely painful, might be “pulsing”, “urgent” or “stabbing”, happen throughout each side of the pinnacle relatively than in a single space, might final for greater than three days and are typically immune to common painkillers.
Runny nostril
Final winter, the ZOE examine discovered {that a} runny nostril was the second mostly reported symptom after complications, with practically 60 per cent of people that examined optimistic for Covid with lack of scent additionally reporting having a runny nostril.
However now the information signifies that the prevalence of the illness is probably the most vital issue. So, when Covid charges are excessive, the probabilities of a runny nostril being as a result of virus are additionally excessive.
The examine additionally stresses that when an infection charges are low, a runny nostril is much less more likely to point out the sufferer has caught the coronavirus and is extra more likely to be as a consequence of a chilly and even an allergy.
It concludes that whereas many individuals with Covid might report a runny nostril, it’s troublesome to name it a definitive symptom as it’s so frequent, particularly throughout winter.
Sneezing
The ZOE examine discovered sneezing greater than ordinary is usually a signal of Covid in individuals who have been vaccinated, though it stresses sneezing is more likely to be an indication of a chilly or an allergy.
It says that despite the fact that many individuals with Covid would possibly sneeze, “it’s not a definitive symptom as a result of sneezing is so frequent”.

In response to ZOE’s knowledge, virtually half of people who find themselves in poor health with Covid report having a sore throat, though that is extra frequent in adults aged between 18-65 than the aged or these underneath 18.
Lack of scent
This continues to be the strongest indicator of Covid an infection, no matter an individual’s age, intercourse or sickness severity.
Whereas individuals who have Covid may not lose their sense of scent fully, it might change, so you might not be capable of scent strongly-scented issues, and your sense of style could also be affected too, so meals might style completely different or appear tasteless.
Persistent cough
A persistent cough is broadly agreed to be one of many three important signs of Covid however, in accordance with the ZOE examine, solely round 4 in 10 people who find themselves in poor health with the virus will expertise this.
On this context, “persistent” means coughing many instances a day, “for half a day or extra”.
A Covid cough is normally a dry cough, in contrast with a chesty one which brings up phlegm or mucus and which will point out a bacterial an infection. A persistent cough tends to reach round a number of days into the sickness and normally lasts for round 4 or 5 days.
