The analysis identified a number of cold-like symptoms associated with Omicron.
The top five symptoms reported in the ZOE app were:
- Runny nose
- Fatigue (either mild or severe)
- Sore throat.
The discovery prompted Professor Tim Spector, lead scientist on the ZOE COVID Study app, to issue important public health advice.
The professor said at the time: “To help us slow the spread, my advice continues to be; avoid gathering indoors, and, if you are meeting up with people, check everyone is free of cold symptoms, test yourself just before and get fully vaccinated.”
