The new OmicronCovid-19 variant is feared to be more transmissible than other mutations and can cause different symptoms than the original coronavirus strain.
The variant, first detected in South Africa, has been categorised as a ‘variant of concern’ by the World Health Organisation (WHO) and has already been found to have 30 different mutations, including traits not previously seen before.
Stricter face masks and self-isolation rules have been introduced in response, while the UK government has announced the booster vaccination programme will now be extended to all adults, with everyone due to be offered a top-up dose by the end of January.
The decision comes amid concerns that Omicron transmits more easily and could potentially evade vaccines, although it is still too early to tell.
New research from South Africa, which has not yet been peer-reviewed, also suggests the variant has “substantial” ability to cause reinfection among people who have previously ha Covid-19.
Findings so far indicate that for most people the variant only causes “mild illness”, although as little is known about the strain, it is possible this could change.
Dr Angelique Coetzee, a private practitioner and chair of South African Medical Association, who first spotted the new variant said that while patients have so far had “extremely mild symptoms”, more time is needed to fully understand the effect it could have on vulnerable people.
Patients have also reported symptoms that differ slightly to those linked to the Delta variant, according to Dr Coetzee.
Listed are six key symptoms that have been associated with the Omicron variant so far, and the difference to other Covid-19 strains.

1. Runny nose
A runny nose has been linked to Omicron infection, although this could easily be mistaken for a symptom of the common cold or flu. A viral infection causes the nose to produce more mucus to help trap and wash away viral particles. Photo: Shutterstock
2. Headache
A headache is another commonly reported symptom of Omicron infection so far. Researchers have previously found that people with coronavirus tend to have moderate to severely painful headaches, or feel pulsing or stabbing pains. Photo: Shutterstock
3. Fatigue
Extreme tiredness has been linked to the new Omicron variant, as well as previous strains. While it is not known how long fatigue can last after Omicron infection, the symptom usually lasts between five to eight days with other variants, although some people can still feel tired for several weeks.

4. Sneezing
Again, this symptom could easily be confused as a sign of cold or flu, but in some cases it could be an indication of Omicron Covid-19 infection. If you sneezing regularly and are worried it could be a sign of coronavirus, it is best to take a test to be sure. Photo: Shutterstock
