British scientists have been able to detect some of the more common symptoms of the new omicron variant that has swept the world, Express reports.

Unlike other forms of COVID-19, Omicron has some unique symptoms that might not be typical of standard coronavirus signs.

According to the NHS, the symptoms of coronavirus generally include "a high temperature, a new, continuous cough, or a loss or change to your sense of smell or taste."

However, people who have contracted Omicron have also noted several other symptoms which aren't usually associated with coronavirus. Among these are nausea and a loss of appetite.

Tim Spector, Professor of Genetic Epidemiology at King’s College London, explained these are common symptoms in those who tend to be double jabbed or even boosted.

He said: "Quite a few of them had nausea, slight temperature, sore throats and headaches."

In some cases, vomiting has also been reported as a symptom among those with the variant.

The four most common symptoms of the omicron variant are cough, fatigue, congestion and runny nose, according to a CDC analysis of the first 43 cases investigated in the US.
