Explained: Can Omicron subvariants give you Covid more than once? | Explained News,The Indian Express

All three variants have been detected in India, but BA.2 – which along with BA.1 caused the January wave in India – continues to be dominant, accounting for 32 per cent of all the genomic sequences submitted to the global database GISAID over the last 30 days.

People who have had an Omicron infection in January are still susceptible to other sub-variants of omicron that are now emerging across the globe, in particular BA.4 and BA.5 that led to a fifth wave of cases in South Africa and is now spreading in Europe, apart from BA.2.12.1 that is driving up infections in the United States.

All three variants have been detected in India, but BA.2 – which along with BA.1 caused the January wave in India – continues to be dominant, accounting for 32 per cent of all the genomic sequences submitted to the global database GISAID over the last 30 days.

Can a person who has had a previous omicron infection get it again?

“Yes, people who have had an Omicron infection in January may get another infection once other sub-variants such as BA.4 and BA.5 start circulating in the community. We have seen these variants take over from BA.2 to become the dominant variant in other countries. They are about 13 per cent to 15 per cent more transmissible than BA.2 which in itself was several-fold more transmissible than the wild type of the virus,” said Dr Lalit Kant, former head of the department of epidemiology and infectious diseases at the Indian Council of Medical Research.

Similarly, BA.2.12.1 that was first detected in New York is thought to be about 27 per cent more transmissible.
