Since the onset of the novel coronavirus, new variants and mutations have continued to emerge, with the Delta variant proving to be the most dangerous of all.

          A new COVID variant "Omicron" has set foot in the world. 

On 26 November 2021, WHO designated the variant B.1.1.529 a variant of concern, named Omicron, It is not yet clear whether Omicron is more transmissible compared to other variants, including Delta.

Experts see this swift jump from being a "Variant of Interest"  to a "Variant of Concern"  as a worrying factor, since the difference between the two is wide-ranging and significant.

Initial reported infections were among university students—younger individuals who tend to have more mild disease—but understanding the level of severity of the Omicron variant will take days to several weeks.  All variants of COVID-19, including the Delta variant that is dominant worldwide, can cause severe disease or death, in particular for the most vulnerable people, and thus prevention is always key.  people, and thus prevention is always key. 

What does it mean to have multiple mutations in the spike protein?

 The new variant Omicron has over 30 mutations in the spike protein, which helps it potentially develop an 'immune-escape mechanism'. The multiple mutations in the spike protein only make the vaccines less effective, leading to decreased efficacy.

 It showcase similar symptoms as the delta variant including fever, sore throat, fatigue, headache and in severe cases shortness of breath, chest pain, etc.
