Omicron Variant

The Omicron variant is a variant of SARS-CoV-2(severe acute respiratory syndrome coronavirus 2 that is the reason of Covid-19, the respiratory illness responsible for ongoing Covid-19 pandemic) 

History of Omicron variant

Until December 2021, it is the newest one. This variant was first reported by WHO (world health organization) from South Africa on 24 November 2021. It was named Omicron by WHO on 26th of November 2021.

The Omicron variant has been detected in many countries all over the world.


There are 60 types of mutations and a significant number affect the Spike Protein (the largest of 4 major structural proteins found in coronaviruses). But still there is substantial uncertainty regarding Omicron and there is also need for a lot of research about its transmittivity, severity and reinfection risk.

When a virus is circulating widely it causes numerous infections. Because of this the virus also get more chances to change its type.


It is not known whether the Omicron variant spread more easily than the highly transmissible delta variant, but many scientists suspect that it may be.

Symptoms and Signs

Until 28 November, there was no information related to Omicron variant symptoms.

Later The Centre for Disease Control found that the most common symptoms were cough, fatigue, and nasal congestion or runny nose.

The unique reported symptom of Omicron is night sweats.

Covid-19 and Omicron Variant

Omicron variant is less severed then Covid-19 because it doesn’t infiltrate the lungs. It is also not conformed whether Covid-19 vaccines is effective against Omicron or not. But it is important to be vaccinated in order to protect yourself against the other circulating variants such as delta variant. If your vaccination includes two doses, it is important to receive both in order to have maximum protection.

The widely used PCR and antigen-based rapid diagnosis tests continue to detect infection of Covid-19, including omicron.

Possible Consequence

The WHO is concerned that a large number of mutations may reduce immunity in people who were previously infected and in vaccinated people. It is also possible that this virus spread rapidly in nation with low vaccinated rates and rate of mortality increases.


Until now there is no effective treatment suggested or proved, but the vaccination reduce the risk of this virus, because the nation with less vaccinated people is affected more from this virus then others.

Safety Preventions

The most important thing you can do is reduce exposure to the virus.

To protect yourself and your family from this virus, make sure to follow following points given bellow:

  • Wear a mask that cover your nose and mouth. Your hand should be properly clean when you put mask on and remove it.
  • Keep a physical distance of about 1 meter from people.
  • Wash your hands properly and regularly.
  • Avoid poorly ventilated or crowded places.
  • Get vaccinated. WHO approved that Covid-19 vaccines are safe and effective to reduce the risk of this virus?
