On condition that the signs related to the unique pressure of Covid-19 and its first variants had been so just like the widespread chilly, it has been tough to inform over the past 12 months or so whether or not the onset of complications and sniffles meant you had contracted the coronavirus or only a bout of typical winter flu – however the subsequent emergence of the Omicron variant has difficult the pictured nonetheless.
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 house take a look at kits, which merely inform us whether or not somebody is Covid-positive or destructive, 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 carry the brand new variant below management towards 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 improve” of individuals in hospital with coronavirus.
Professor Spector mentioned that information from the ZOE research app means that about half of all instances of Delta are being “missed” as a result of persons 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 steerage, whereas a light case might not end in the entire circumstances on that guidelines being skilled.
“Omicron might be rather more just like the delicate 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’ll be producing cold-like signs that folks gained’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 exhibits that individuals who’ve obtained two doses of the vaccine usually current with much less extreme signs, reminiscent of headache, runny nostril, sneezing, sore throat and lack of scent.
“It’s essential for individuals who’ve been totally vaccinated to remain vigilant for cold-like signs and get examined in the event that they’re residing or working round people who find themselves at better threat from the illness.”

Professor Irene Petersen, a professor of epidemiology and well being informatics at College Faculty London, provides: “A runny nostril and headache are signs of many infections, however can also be the primary signs – and solely signs – of Covid. Due to this fact, when you have these signs, I’d encourage you to make use of lateral stream exams for a few days.
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’ve been vaccinated or not.
Headache
Though complications are a much less well-known symptom of Covid, they’re one of many earliest indicators, in keeping with the ZOE research, and are extra widespread than the traditional signs of cough, fever and lack of scent.
The research discovered Covid complications are typically reasonably to severely painful, could be “pulsing”, “urgent” or “stabbing”, happen throughout each side of the pinnacle fairly 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 research discovered {that a} runny nostril was the second mostly reported symptom after complications, with practically 60 per cent of people that examined constructive for Covid with lack of scent additionally reporting having a runny nostril.
However now the info signifies that the prevalence of the illness is probably the most vital issue. So, when Covid charges are excessive, the possibilities of a runny nostril being because of the virus are additionally excessive.
The research additionally stresses that when Covid 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 on account of a chilly and even an allergy.
It concludes that whereas many individuals with Covid might report a runny nostril, it’s tough to name it a definitive symptom because it’s so widespread, particularly throughout winter.
Sneezing
The ZOE research discovered sneezing greater than regular is usually a signal of Covid in individuals who’ve been vaccinated, though it stresses sneezing is more likely to be an indication of a chilly or an allergy.
It says that although many individuals with Covid would possibly sneeze, “it’s not a definitive symptom as a result of sneezing is so widespread”.
Sore throat
Many individuals with Covid have reported by way of the ZOE Research app that they’ve a sore throat that feels just like one you would possibly expertise you get when you could have a chilly or laryngitis.
Covid-related sore throats are typically delicate and final not more than 5 days so a really painful one which lasts longer is more likely to be one thing else. If it persists, you need to contact your GP.
Though it may be a Covid symptom, most individuals with a sore throat will most likely simply have a chilly. In keeping with ZOE’s information, nearly half of people who find themselves unwell with Covid report having a sore throat, though that is extra widespread in adults aged between 18-65 than the aged or these below 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 won’t lose their sense of scent fully, it could change, so it’s possible you’ll not have the ability to 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 extensively agreed to be one of many three principal signs of Covid however, in keeping with the ZOE research, solely round 4 in 10 people who find themselves unwell 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 that will point out a bacterial an infection. A persistent cough tends to reach round just a few days into the sickness and normally lasts for round 4 or 5 days.
Alan McNally, a professor of microbial evolutionary genomics on the College of Birmingham, who was infectious illness lead on the Milton Keynes Lighthouse Lab – the UK authorities’s first flagship Covid testing facility – provides: “You probably have any signs of respiratory an infection, you need to keep at house to forestall transmission and get a take a look at completed.
“Attempting to self-diagnose is a certain hearth solution to ship Covid case charges hovering once more.”
