In a statement, the WHO said, “Based on the evidence presented indicative of a detrimental change in COVID-19 epidemiology, the TAG-VE has advised WHO that this variant should be designated as a VOC, and the WHO has designated B.1.1.529 as a VOC, named Omicron.”

What are the features of Omicron variant

The National Institute for Communicable Diseases of South Africa stated that there are currently no exceptional symptoms following the transition to B.1.1.529. However, patients infected with Omicron variant do not show symptoms as patients with delta-like variants.

What caution people and individuals should take

The WHO said countries could increase testing and make efforts to better understand SARS-CoV-2. People, on the other hand, should wear full face masks and do handwashing and maintain social distance, ensuring adequate ventilation even inside the house. People should not overcrowd and get vaccinated on time.
