The variant of SARS-CoV-2 B.1.1.529, termed Omicron, was labelled a variant of concern by World Health Organisation (WHO) on November 26, 2021. The number of people testing positive has risen in areas of South Africa affected by this variant. Scientists in and outside of South Africa are carrying out several research projects to comprehend Omicron better.

Compared to other variations, including Delta, it is not yet clear if Omicron is more transmissible. Also, Omicron infection has not yet been proven more dangerous than infection with other forms. Initial data suggests that hospitalisation rates in South Africa have increased; however, this may be due to an increase in overall infection rates, rather than a specific infection with Omicron, as previously thought. When it comes to the most vulnerable persons, all forms of COVID-19 (including the dominant Delta version) can cause severe sickness or death, so prevention is always crucial.

Initial evidence suggests that Omicron may be more likely to re-infect patients. WHO is collaborating with technical partners to determine how this variation may affect existing countermeasures, such as vaccines. Vaccines are still needed to combat serious sickness and mortality, including Delta. Vaccines still protect against severe disease and death.
