Coronavirus: Omicron sub-variant XBB found in India, those not taking Covid booster dose at more risk

New Delhi: The new sub-variant of Omicron, known as XBB, has been found in India. XBB has already led to increase in the cases of corona infection in Singapore by more than four times. 

Cases increased in Singapore: In the last one month, cases of re-infection have increased from 15 to 70 percent in Singapore. All these cases are those who had received vaccination seven to eight months back.

Dr. Vinod Scaria, Senior Scientist, Institute of Genomics and Integrative Biology (CSIR-IGIB), Delhi, said that recently a new sub-variant form of Omicron has been identified through genome sequencing

Sub-variant found in Bangladesh, Europe and America: Apart from India, this sub-form has been found in many states of Bangladesh, Europe and America. It is believed to be the main reason behind the increase in cases of infection in Singapore.

Risk for those who do not take the precautionary dose: Dr. Scaria told that the XBB sub-variant is attacking antibodies in people. Therefore those who have not yet taken the precautionary or booster dose of anti-coronavirus should not delay. People should also follow the covid vigilance rules.

Singapore’s senior Dr. Septin Hartoonu has informed on social media that between October 1 and 14, 162 cases of re-infection have been registered in their population of one lakh, which is almost double compared to September (78).

Has the strongest ability by far to evade vaccine protection: According to experts, XBB has the strongest ability by far to evade vaccine protection. Leading expert Dr Gilman Siu Kit-hang warned that there could be more strains during the winters. He said this subvariant is more evasive to vaccine immunity than other known variants.

The expert said that more mutant strains were expected to emerge in the winter throughout the world.
