Covid 19 What are the Symptoms of Omicron
Symptoms of Omicron
What are the Symptoms of Omicron: Using the most recent data from London, where Omicron prevalence is higher than other regions of the UK, ZOE data scientists analyzed symptom data from positive cases recorded in the ZOE COVID Study and compared with data from early October when Delta was dominant.
This analysis found no clear difference in the symptom profile of Delta and Omicron, with only 50% of people experiencing the classic three symptoms of fever, cough, or loss of sense of smell or taste.
The top 5 symptoms in both periods were:
- Runny nose
- Fatigue (mild or severe)
- Sore throat
Newly Discovered Symptoms
- Night Sweat
Contributor reports also identified loss of appetite and brain fog as common symptoms.
These findings line up with a small batch of data from contributors who reported that their positive PCR results were suspected or confirmed Omicron infections.
This may come as a surprise to some, as the UK government never updated guidance on COVID symptoms beyond the classic three symptoms. Many months ago, the ZOE COVID Study helped to identify over 20, mostly mild, cold-like symptoms.
Does Omicron cause more hospitalizations and deaths than Delta?
Even as cases rise, the proportion of hospitalizations and deaths seems to be dropping in most countries where Omicron has been detected. The same is true of our analysis of London, although there is often a delay between catching COVID and being hospitalized with complications, so this might change in the coming weeks.
So far, we’ve had no reports from people who have been hospitalized or suffered severe symptoms with a suspected Omicron infection. In fact, there’s been an 8% drop in UK COVID hospitalizations from 987.7 a week on the 15th of November to 811 a week on the 15th of December.
If the symptoms are mild, why should I worry about Omicron?
News about Omicron has caused alarm across the globe with good reason. We still have a lot to learn about Omicron and it’s not yet clear what kind of pressure it will put on global health systems. We’ve seen some countries experience surges in their hospitals, but it’s important to remember that every region is unique, with unique demographics and rates of vaccination.
Even though we expect the proportion of hospitalizations and deaths per positive case to decline, if the rate of cases gets very high, we will inevitably see a high volume of death and hospitalization. It’s worth noting, that while the UK abandoned restrictions some time ago, people have continued to be hospitalized and have died with COVID-19.
