The XE variant is what is called a ‘recombinant’. This means it contains the mutations found in BA.1 as well as BA.2 varieties of Omicron.
Covid-19 XE Variant: India, total cases, symptoms, what is
This was first discovered in the United Kingdom in January, and so far more than 600 samples of XE have been found in different countries.
Recombinant variants are not uncommon. Variants that contain mutations characteristics of two or more known variants occur all the time.
In fact, variants that contain the characteristic mutations of Delta and Omicron have also been identified.
Covid-19 XE Variant India
The Maharashtra government and the Centre appeared to be at loggerheads on Wednesday over the announcement of the first domestic case of Omicron-XE variant, the most transmissible Covid-19 strain to date.
While the BMC claimed in Mumbai it had found the XE strain in the sample of a South African costume designer who tested positive in Mumbai over a month back, central agencies said the diagnosis was wrong.
At the end of the day, the Maharashtra government said GISAID (global genomic data) had confirmed XE, while INSACOG (the Indian SARS-CoV-2 Genomics Consortium) has decided to go for another round of genomic sequencing at the National Institute of Biomedical Genomics (NIBMG), West Bengal, for confirmation. A note given by the state government said, “Mumbai has a probable XE case.”
In latest update, Covid-19 XE— the dreaded sub-variant of Coronavirus’ Omicron variant — has been detected in Mumbai municipal area, the Brihanmumbai Municipal Corporation (BMC) said on Wednesday.
However, soon after, official sources refuted saying that the scientific evidence so far does not indicate it to be so and added that present evidence doesn’t suggest that it’s ‘XE’ variant.
ANI quoted sources as saying that FastQ files of the sample (being said to be ‘XE’ variant) were analysed by INSACOG genomic experts who inferred that genomic constitution of this variant doesn’t correlate with genomic picture of ‘XE’ variant.
According to the official data shared by the Ministry of Health on Wednesday, India reported 1,086 new coronavirus infections in a single day which took the country’s total tally to 4,30,30,925.
The country’s total death toll climbed to 5,21,487 with 71 fresh fatalities. The Ministry informed that the active cases comprise 0.03 per cent of the total infections, while the national COVID-19 recovery rate remained at 98.76 per cent.
Covid-19 XE Variant symptoms
The symptoms can be mild for some and they can be severe for others. The newest variant spreads rapidly.
Depending on one’s vaccination status and immunity acquired from earlier infections, symptoms and severity of the Covid-19 virus depend from person to person.
Some of the symptoms to watch out for include fever, sore throat, scratchy throat, cough and cold, skin irritation and discolouration, gastrointestinal distress, etc.
Some of the symptoms of severe diseases are heart ailment, palpitation, and sometimes the virus can also cause severe nerve diseases.
Fatigue and dizziness are some of the initial symptoms, followed by headaches, sore throat, muscle soreness and fever.
The Omicron variant, which is responsible for over 90 per cent of the infections detected this year, has two prominent sub-variants, called BA.1 and BA.2. There is a BA.3 sub-variant as well, but that is less common.
During the initial phase, the BA.1 sub-variant was the most widespread. In India, however, it was the BA.2 that was the most dominant during the third wave.
BA.2 was found to be slightly more transmissible than BA.1, even though it was not more dangerous. In the last couple of months, the BA.2 variety has become the most widespread across the globe, accounting for almost 94 per cent of all Omicron infections in the last one month, according to the World Health Organisation (WHO). The incidence of the BA.1 variety is declining sharply.
The XE variant is what is called a ‘recombinant’. This means it contains the mutations found in BA.1 as well as BA.2 varieties of Omicron. This was first discovered in the United Kingdom in January, and so far more than 600 samples of XE have been found in different countries.
