Lateral movement assessments offered a solution however the subsequent emergence of the brand new Omicron variant in late November has difficult the image nonetheless additional as its signs are barely totally different – stuffy nostril, sore throat – and since it can’t but be particularly recognized by residence check kits, which merely inform us whether or not somebody is Covid-positive or detrimental, 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 underneath management towards hovering an infection charges.
He 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 protracted cough and a loss or change of scent or style they’ve been informed to anticipate by the official steerage, whereas a light case might not lead to all the circumstances on that guidelines being skilled.
“Omicron might be way 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’s going to be producing cold-like signs that individuals gained’t recognise as Covid if they simply imagine the official authorities recommendation.”

The ZOE Covid Symptom Examine, which is funded by the UK authorities, 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 accordance with the ZOE examine, and are extra widespread than the traditional signs of cough, fever and lack of scent.

Runny nostril
Final winter, the ZOE examine discovered {that a} runny nostril was the second mostly reported symptom after complications, with almost 60 per cent of people that examined optimistic for Covid with lack of scent additionally reporting having a runny nostril.
However now the info signifies that the prevalence of the illness is essentially the most important issue. So, when Covid charges are excessive, the possibilities of a runny nostril being as a result of virus are additionally excessive.
The examine 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 resulting from 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 because it’s so widespread, particularly throughout winter.
Sneezing
The ZOE examine discovered sneezing greater than regular could be 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”.

In accordance with ZOE’s knowledge, virtually half of people who find themselves ailing with Covid report having a sore throat, though that is extra widespread 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 won’t lose their sense of scent utterly, it could 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 totally different or appear tasteless.
Persistent cough
A persistent cough is broadly agreed to be one of many three major signs of Covid however, in accordance with the ZOE examine, solely round 4 in 10 people who find themselves ailing 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 often 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 couple of days into the sickness and often lasts for round 4 or 5 days.
