For risk assessment, amidst fears of an epidemic relapse, once a new mutant from the new corona virus was announced, late November, scientists rushed to their laboratories.

When the World Health Organization (WHO) announced the name "Omicron" for the new mutant, researchers had reinstated the work of their counterparts in South Africa, in order to take a clearer idea of the mutations that had occurred.

Scientists have been filming genetic changes that have turned omicron into a new and disturbing element in the Corona family that has left the world in a nightmare, since late 2019.

According to the data, many mutations observed in the omicron mutant are already present in earlier mutants of the new corona virus.

Scientists do not yet know whether this new mutant is different from previous mutants, particularly the Delta mutant, which dominates most of the world's recorded infections.

It is estimated that the world may require days and perhaps several weeks of testing, before the impact of the new mutations observed in Omicron can be explained.

Scientists will rely mainly on real samples of people who have been infected with corona, and then researchers will be able to monitor the sequences in the genome of the mutant.

Researchers seek to see whether the new mutant causes a more severe disease in Covid-19 or is it the fastest spread, and whether Omicron will be more able to avoid the immunity the vaccine gives to the human body.
