A new strain of omicron coronavirus continues to spread around the world. However, the increase in the number of cases allows scientists to study a new variant, which means to find the most common symptoms for it.
Unlike other forms of COVID-19, omicron has unique traits that may be atypical for other strains. According to the UK’s National Health Service, symptoms of coronavirus usually include high fever, continuous coughing, loss or change in sense of smell or taste. However, people who have contracted omicron may experience nausea and loss of appetite.
Tim Spector, professor of genetic epidemiology at King’s College London, explained that these are common symptoms in those who have fallen ill after full vaccination or revaccination.
“Many of the patients had nausea, a slight fever, sore throat and headaches,” he notes.
Vomiting has also been reported in some cases. According to an analysis by the US Centers for Disease Control and Prevention (CDC), the first 43 cases studied in the US identified the four most common symptoms of omicron:
- cough;
- fatigue;
- nasal congestion;
- runny nose.
