are classified as ‘variants under surveillance’ – meaning that they may require priority attention and tracking by health authorities due to their increased spread and potential health risks. NB.1.8.1 and XFG are among them. NB.1.8.1 has been informally nicknamed “NIMBUS” while XFG is being called STRATUS. STRATUS is believed to be more contagious The WHO said in its latest update on 23 May 2025 that preliminary research and evidence on NB.1.8.1 suggests that NB.1.8.1 is a form of the Omicron variant, which is not as virulent and severe. The infectiousness of this variant is certainly high but it does not pose any additional public health risk. The STRATUS or XFG variant was first detected in Canada and has rapidly affected the global population. By the end of May, Europe had 25% of its cases, while NB.1.8.1 cases were 9%. It is also spreading in India, where there were 206 active cases of Corona as of June 11, which increased to 7400 by June 15. However, it is now steadily decreasing.

Health experts are already saying that such fluctuations in Corona cases can continue in a country with a large population like India. Since the risk of infection is constant, it is important for all people to continue taking preventive measures. The speed of infection can be reduced by following COVID-appropriate behavior (mask, avoiding crowds, hand hygiene). At the beginning of this wave of Omicron subtypes (NB.1.8.1 and XFG) in the country, Dr. Anish Sinha said that the faster the infection increases in the country, the faster its cases will decrease.
