Introduction: Omicron is the mutated strain of the SARS-CoV-2 (COVID-19 virus) reported to have more than 50 mutations, including 32 on its spike protein, and 26 of them have never been seen before. It is a worrying variant because of its mutations and more transmissibility. The mutations on the spike proteins make it tough for the immune system to carry out virus neutralization. This is because spike protein helps the virus bind to a cell, enter it, and then seize it to convert it into a virus-producing factory. It is the part of the virus i.e. targeted by the COVID-19 vaccine to teach the person’s immune system to recognize and attack the coronavirus. Omicron's name is designated by the World Health Organisation and is put in the list of 'variants of concern' after the other four-alpha, beta, gamma, and delta on 26th November 2021. The first incidence of this virus was in South Africa followed by the U.S. Later this variant has set alarming shock waves across various countries of the globe. So far, it has been spread at an unprecedented rate worldwide. It has been found to spread more than twice quickly as Delta. Symptoms In Patients Infected By Omicron Variant: The signs of COVID-19 linked to the omicron variant are described as "extremely mild". So, most infected patients can be recovered by hospitalizations. However, some symptoms include:
- A scratchy throat
- Cough, congestion, and runny nose
- Extreme tiredness (found in every age group)
