Nine Omicron Covid Symptoms Affecting the Fully Vaccinated — And Signs You May Have It

China has imposed strict new lockdown measures in Shanghai as the country ramps up efforts to stave off another round of coronavirus infections after they bounced back to a two-year high in May.

The Asian powerhouse has taken some of the most drastic measures since the start of the pandemic in recent weeks, even though the caseload is low compared to other major countries as it has committed itself to an uncompromising ‘zero-covid’ strategy.

The latest increase in cases is believed to be due to Omicron, reportedly the dominant variant, which devastated the UK over Christmas and New Years.

First discovered in southern Africa in November 2021, it quickly spread around the world last December, showing that it is more easily transmissible, but less severe than its birthmark.

Here we take a look at some of the most common symptoms associated with the fully vaccinated variant — and two early warning signs that you may have it.

Most common symptoms in fully vaccinated

Researchers in Norway conducted a survey of 111 of 117 guests at a party on November 26, 2021 where there was an Omicron outbreak. Of the group interviewed, 66 had definitive cases of Covid-19 and 15 had possible cases of the virus.

Of the 111 participants, 89 percent had received two doses of an mRNA vaccine and none had received a booster shot.

According to the findings published in the Journal of Infectious Diseases and Epidemiology Eurosurveillancethere were eight key symptoms experienced by the group of fully vaccinated partygoers.

These were: a persistent cough, runny nose, fatigue, sore throat, headache, muscle aches, fever, and sneezing.

The study found that coughing, runny noses and fatigue were among the most common symptoms in the vaccinated individuals, while sneezing and fever were the least common.

Public health experts also added nausea to this list of symptoms in vaccinated people who contracted the Omicron variant.

Although the vaccine protects against the more serious risks of the virus, it is still possible to contract Covid even if you have both shots and a booster shot.

The mild nature of the symptoms makes it difficult for people to distinguish the virus from a cold.

But according to Professor Tim Spector, behind the ZOE Symptom Study App, about 50 percent of “new colds” right now are in fact Covid.

Two Early Warning Signs You May Have Omicron

Experts also suggest that there are two distinct symptoms that could be a sign that a positive test is around the corner: fatigue and periods of dizziness or fainting.

Fatigue can not just make you feel tired but can translate into physical pain by causing sore or weak muscles, headaches and even blurred vision and loss of appetite.

dr. Angelique Coetzee, a private practitioner and president of the South African Medical Association, said: Good morning Great Britain that fatigue was one of the main symptoms of Omicron when the variant broke out in South Africa.

In fact, 40 percent of women reported struggling with fatigue due to Covid compared to a third of men, according to a WebMD poll that asked users how often they had experienced fatigue from Dec. 23, 2021 to Jan. 4. 2022.

Dizziness or fainting is the second sign that you have Omicron.

A report from Germany recently suggested there could be a link between fainting and Omicron after doctors in Berlin found that Covid was causing recurrent vertigo in a 35-year-old hospitalized patient.

German newspaper Arztezeitung said the doctors could see a “clear link” between the infection and the fainting spells.
