What are the omicron variant symptoms?

The ZOE COVID Study, which has analyzed thousands of COVID-19 cases, has identified most of the symptoms from when the omicron variant began to rise in the United Kingdom, as I wrote about for the Deseret News.

Per CNBC, the top symptoms so far include:

1. Runny nose.
2. Headache.
3. Fatigue (either mild or severe).
4. Sneezing.
5. Sore throat.
