So far, three recombinant lineages XD, XF (recombination of Delta variant and BA.1 lineage of Omicron), and XE have been reported from SARS-CoV-2 variants of concern by the UK Security Agency in England, on March 25, 2022 (5✔ ✔Trusted Source

However, Britain has accounted for less than 1% of the infection rate from the XE variant with approximately 1,100 confirmed cases as of April 5th, 2022 (1✔ ✔Trusted Source

Is the XE Variant Dangerous?
XE may be 10% more transmissible than BA.2 variant (2✔ ✔Trusted Source

“XE’s transmissibility is certainly higher than that for BA.1 or BA.2. If people’s international mobility increases, XE has a high chance of replacing the current omicron variants. But we still don’t know the severity of symptoms among the infected people, so we need to examine the epidemiological impact of the variant closely,” says Hiroshi Nishiura, a mathematical modeling expert at Kyoto University (1✔ ✔Trusted Source

Transmissibility Rate in India
The first XE case in India was reported on April 9th, 2022 as a 67-year-old man (Vadodara resident) traveled from Mumbai to Gujarat (confirmed by genetic sequencing results) (3✔ ✔Trusted Source

The man suffered from a mild fever on March 12th and tested positive for COVID-19 on March 13th, 2022, as per the Ministry of Health and Family Welfare. However, the man recovered within a week (4✔ ✔Trusted Source

So far, two cases of the XE variant have been detected in India, one from Maharashtra and the other from Gujarat.
Another case of XE variant in India was reported in a 50-year-old asymptomatic South African National female as per a bulletin issued by The Integrated Disease Surveillance Programme (IDSP) Public Health Department, Maharashtra on Wednesday (April 6th, 2022) (5✔ ✔Trusted Source

The woman tested positive for COVID-19 on February 27th, 2022, with a travel history from South Africa to India on February 10th, 2022.
However, her repeat RTPCR testing, and repeat genomic analysis by Indian SARS-CoV-2 Genomics Consortium (INSACOG) and the Union health ministry denied the genomic constitution of the ‘XE’ variant (5✔ ✔Trusted Source

Nevertheless, with rising cases in India, the INSACOG continues to monitor the genome sequencing of the circulating COVID-19 strains (5✔ ✔Trusted Source

“Omicron is giving rise to many new variants. It’s part of the X series like XE & others. These variants will keep on occurring. Nothing to panic about as none of these are causing serious diseases or at the moment from Indian data it doesn’t show a very rapid spread,” says Dr. NK Arora, National Technical Advisory Group on Immunisation (NTAGI) chief and COVID-19 task force chairman to ANI (3✔ ✔Trusted Source

Follow COVID Appropriate Precautions
Globally, the experts recommend the need for country-wide genomic surveillance and implementation of a COVID appropriate behavior including the campaign for additional COVID-19 vaccinations, cautioning for the emergence of the fourth wave between June and August 2022 (1✔ ✔Trusted Source

“There will be newer variants that appear, and we will need to watch out for those that are more virulent (cause more severe disease). We need to ensure that vulnerable individuals are protected with vaccinations, and boosted when warranted. I do not think we should sensationalize newer variants and cause panic unless they are indeed variants which are likely to cause more severe disease,” says Dr. Lancelot Pinto, consultant pulmonologist and epidemiologist at PD Hinduja Hospital (5✔ ✔Trusted Source
