Omicron: All you need to know about the new COVID variant

A novel Covid-19 variant was reported to the World Health Organization on November 24, 2021. This new variation was reported in Botswana on November 11, 2021, and in South Africa on November 14, 2021.

On November 26, 2021, WHO designated the new variant as Omicron. The United States declared Omicron as a Variant of Concern on November 30, 2021, and the first verified US case of Omicron was found on December 1, 2021.

How easily does the Omicron variant spread?

The Omicron variant is more transmissible than the original SARS-CoV-2 virus, but it remains uncertain whether it is more transmissible than the delta variant. The CDC believes that anyone infected with Omicron will be able to transfer the virus to others, even if they have been vaccinated or do not show any symptoms.

Will the Omicron variant cause more severe illness? 

More data is required to determine if Omicron infections, particularly reinfections and breakthrough infections, occur in patients who have been completely vaccinated. However, there are early indications that it may induce symptoms other than those that have become so well-known.

Are vaccines effective against the Omicron variant?

Current vaccinations are predicted to protect against severe illness, hospitalizations, and fatalities caused by Omicron variant infection. Breakthrough infections are more probable in those who have been completely vaccinated. Vaccines against other variants, such as Delta, have remained effective in averting severe disease, hospitalizations, and death. The new development of Omicron underscores the necessity of immunization and booster shots.
