Data continues to point to the view that the variant only produces mild cold like symptoms in the vast majority of people.
Experts have revealed the signs and symptoms are very similar to a common cold.
Professor Tim Spector OBE, from the ZOE Symptom Covid Study App, has said Omicron symptoms and tell tale signs could be anything from a runny nose and headache to fatigue and husky voice.
Congestion, sneezing and night sweats have also been linked to the new variant.
