All viruses, including SARS-CoV-2, change over time. Most changes exert little effect on the characteristics of the virus. However, some changes can affect the characteristics of the virus, such as the spreading rate, the severity of the disease, or counteract the effectiveness of vaccines, therapeutics, diagnostic tools, or other public and social health measures. The B.1.1.529 variant of SARS-CoV-2 was first reported to the World Health Organization (WHO) on November 24, 2021 from South Africa. On November 26, the WHO, on the advice of scientists from the Technical Advisory Group, identified the variant as a concern variant and called it Omicron. Omicron, along with Alpha, Beta, Delta and Gamma variants, is currently on the WHO list of concern variants. This variant harbor many mutations, some worrisome. Preliminary evidence suggests an increased risk of re-infection with this variant compared to others. Researchers around the world are competing to understand the danger this variant could pose to the world. However, it may take weeks for scientists to get a more complete picture of the Omicron and gain an understanding of its ability to transmit and the severity of the disease, as well as its potential to escape the immunity provided by current vaccines.
