Symptoms of Omicron: Points to note from the Covid variant

Given the symptoms associated with the original strain of COVID-19 Its first variant was so similar to a common cold that it was difficult to determine if a headache or snuff onset last year or so meant you had a cold. coronavirus Or a traditional winter flu attack-but its subsequent appearance Omicron Variants made the photo even more complicated.

The symptoms of the new variant are slightly different-stuffy nose, sore throat-and which strains they infect because it’s still not clearly identified by a home test kit that tells you if someone is Covid positive or negative. I didn’t do it.

Tim Spector, a professor of the ZOE Covid app in the UK, said it’s more important than ever to take a test in the absence of symptoms so that new variants can be controlled against spikes in infection rates. ..

Dr. Chaand Nagpaul, chairman of the British Medical Association’s council, said he was concerned about a “significant increase” in the number of people hospitalized with the coronavirus.

Approximately half of all Delta cases ” It is a scent and taste symptom that is said to be expected in official guidance, but in mild cases, all conditions on the checklist are experienced. Not always.

“Omicron is probably much more like the mild variants found in vaccinated people. [but still subsequently taken ill] Above all in Delta, “he said.

“Therefore, simply believing in official government advice will cause cold-like symptoms that people do not recognize as Covid.”

Christina Marriott, Chief Executive Officer Royal Society for Public Health “Growth evidence is that people who have been vaccinated twice usually have less serious symptoms such as headaches, runny nose, sneezing, sore throat, and loss of odor.

“It is important for fully vaccinated people to be aware of cold-like symptoms and to test whether they live or work around people at high risk of illness.”

Professor Irene Petersen, Professor of Epidemiology and Health Informatics University of London, Adds: “A runny nose and headache are symptoms of many infections, but they are the first and possibly the only symptoms of Covid. Therefore, if you have these symptoms, use immunochromatography for several days. recommend to.”

The ZOE Covid Symptom StudyWith government funding, it identifies the main symptoms associated with Covid and states that it varies slightly depending on whether or not it is vaccinated.


Headache is a lesser-known symptom of Covid, but according to ZOE studies, it is one of the earliest signs and is more common than typical symptoms such as coughing, fever, and loss of odor.

Studies show that Covid’s headaches tend to be moderate to severe, sometimes “pulsing,” “pushing,” and “stabbing,” occurring on both sides of the head rather than in one area, for more than 3 days. It may continue. Resistant to regular painkillers.


Last winter, a ZOE study found that runny nose was the second most reported symptom after headache, with nearly 60% of people who had no odor on Covid’s test also reported runny nose. ..

But now, the data show that the prevalence of the disease is the most important factor. Therefore, if the Covid rate is high, the runny nose is also more likely to be caused by the virus.

The study also emphasizes that if the infection rate is low, a runny nose is unlikely to indicate that the patient has been infected with the coronavirus and is likely due to a cold or allergy.

Many people in Covid may report a runny nose, but conclude that it is difficult to call it a definitive symptom, as it is so common, especially during the winter months.


A ZOE study emphasizes that sneezing is much more likely to be a sign of a cold or allergy, but sneezing more than usual can be a sign of Covid in a vaccinated person. There is sex.

Many people with Covid may sneeze, but it says, “Sneezing is so common that this is not a definitive symptom.”

sore throat

Many people using Covid report through the ZOE Study app that they have a sore throat similar to what they experience when they have a cold or laryngitis.

Very painful sore throat can be something else, as Covid-related sore throats tend to be mild and last only within 5 days. If that persists, you will need to contact your GP.

It can be a symptom of Covid, but most people with a sore throat will probably catch a cold. According to ZOE data, almost half of people infected with Covid report sore throat, which is more common in adults aged 18-65 than in the elderly and under 18 years of age. is.

Loss of odor

It remains the strongest indicator of Covid infection, regardless of a person’s age, gender, or severity of the disease.

People with Covid may not lose their sense of smell altogether, but it can change, so they can’t smell strong scents and can affect their taste sensation. there is.

Persistent cough

Persistent cough is widely accepted as one of Covid’s three main symptoms, but according to a ZOE study, only 4 out of 10 people infected with the virus experience this. To do.

In this context, “persistent” means coughing “more than half a day”, many times a day.

Covid coughs are usually dry coughs, as compared to chest coughs, which cause sputum and mucus and can indicate a bacterial infection. Persistent cough tends to arrive about a few days after the illness and usually lasts about 4-5 days.

Alan McNally, a professor of microbial evolution genomics at the University of Birmingham and leader of infectious diseases at the Milton Keynes Lighthouse Institute, the UK’s first flagship Covid testing facility, adds: I’m at home to prevent infection and get tested.

“Attempting self-diagnosis is a surefire way to boost Covid’s case rate again.”
