Symptoms of Omicron variant continue to come forward as COVID-19 cases continue.
Omicron has been reported to be highly transmissible but evidence show that is less severe than the other coronavirus variants.
People with Omicron are most often reporting these five symptoms:
- sore throat,
- runny nose,
- and sneezing.
However, infected people with the Omicron strain may also experience one or more of the symptoms below:
- loss of appetite,
- brain fog,
- and night sweats.
Brain fog refers to a sense of forgetfulness, confusion and lack of mental clarity.
The insight into the symptoms of the Omicron variant comes from the UK-based ZOE COVID study.
The study has been monitoring the effects of the new Omicron variant.
Professor Tim Spector who specialises in genetic epidemiology and the lead scientist of the ZOE COVID study, said:
“Nausea and loss of appetite tended to be more common in those who were fully vaccinated and boosted.”
Although evidence on night sweats are inconclusive, some people who tested positive for Omicron have reported experiencing this symptom.
How Omicron is different with Delta
So far the data suggests that the Omicron variant of COVID, while spreading quicker, is milder than other variants such as Delta.
The proportion of people being hospitalised with the disease in many countries is lower than with Delta.
While it is possible that Omicron is milder, it is also true that many people around the world have built up natural immunity due to infection and vaccination.
Evidence also suggests unlike Delta that replicates in the lung, Omicron multiples in the upper respiratory tract which include the nose, mouth, and throat.
This maybe one of thee reason why Omicron is less severe than Delta.
It may also partly explain why Omicron is highly transmissible between people due to its nasal replication (runny nose and sneezing).
