Explained: What is the new XFG variant detected in India amid rising Covid cases?
A newly emerging strain called 'XFG' has now been detected in India, with the Covid-19 case tally surpassing 6,500. According to Insacog, the government agency monitoring the different variants, as many as 163 cases of the XFG variant have been reported in India so far, with the most from Maharashtra (89).

India is once again seeing a rise in Covid-19 cases, and this time, a new sub-variant is also in the mix.
While the JN.1 variant of Omicron has been around for a while, a newly emerging strain called 'XFG' has now been detected in the country, raising fresh concerns as infections are creeping up again.
According to the Indian SARS-CoV-2 Genomics Consortium (Insacog), which monitors how the virus which causes Covid-19 evolves, as many as 163 cases of the XFG variant have been reported across India so far.

This rise in cases comes alongside a steady climb in active infections across the country.
According to the Union Health Ministry, India has now recorded over 6,500 active Covid-19 cases, with 769 new cases reported in just the last 48 hours.
So, what exactly is this XFG variant? And does it pose a serious threat? Are vaccines effective against the new variant? Here's what we know so far
Covid-19 in India: What is the XFG variant?
The XFG variant is a recombinant subvariant of the SARS-CoV-2 virus—essentially, it's the result of two earlier strains, LF.7 and LP.8.1.2, merging together.
Recombinant variants like XFG typically emerge when someone is infected with two different versions of the virus at the same time, allowing the virus to 'mix and match' its genetic code.

According to The Lancet journal, XFG falls under the Omicron family of Covid-19 variants, which has been the dominant global strain since late 2021. It was first detected in Canada.
The study also points out that the XFG variant shows 'strong immune evasion'—meaning it has the ability to dodge the body's natural immune defences, helping it survive longer and spread more easily.
Where are the XFG cases in India?
The latest data from Insacog shows that India has reported 163 cases of the XFG variant so far.
Maharashtra has recorded the highest number with 89 cases, followed by Tamil Nadu (16), Kerala (15), Gujarat (11), and Andhra Pradesh, Madhya Pradesh, and West Bengal, each with six cases.

Most of these infections—159 cases—were detected in May 2024, while two each were reported in April and June.
Is there a reason to worry?
For now, the answer seems to be no.
There is currently no evidence suggesting that the XFG variant causes more severe illness or leads to higher death rates compared to other Omicron sub-variants.
As with most strains that evolved from Omicron, XFG is mostly associated with mild upper respiratory symptoms, particularly in people who are vaccinated or have previously recovered from Covid-19.
So far, XFG has not been labelled a Variant of Concern (VOC) or Variant of Interest (VOI) by either the World Health Organisation (WHO) or India's Ministry of Health. That means it hasn't been linked to serious outbreaks, a rise in hospitalisations, or issues with vaccine effectiveness—at least not yet.
That said, health experts remain cautious.
The virus is still evolving, and variants that evade immunity or develop mutations that improve their ability to bind to human cells (especially through the spike protein) could cause future waves if not closely watched.

'According to Indian Council of Medical Research (ICMR) data, 66 per cent of current respiratory viral infections in India are Covid-related. However, hospitalisation is low, including in Telangana. People with two or more comorbidities, weakened immunity, or above 70 years should remain alert,' Dr Kiran Madala, who is also a professor at Gandhi Medical College, told The Times of India.
Are vaccines effective against the XFG variant?
The good news is that India's current Covid-19 vaccines, including Covaxin, Covishield, and the newer booster shots, are still believed to provide protection against severe illness and hospitalisation from the XFG variant.
Health experts say that while mild breakthrough infections can still occur, especially as antibody levels decline over time, the T-cell immunity developed through vaccination is likely to stay effective.
Covid-19 cases cross the 6,500 mark
According to the Ministry of Health and Family Welfare, India's active Covid-19 cases have now surpassed 6,500, pointing to a steady uptick in infections.
The Ministry also confirmed 65 Covid-related deaths across Uttar Pradesh, West Bengal, Tamil Nadu, Punjab, Maharashtra, Madhya Pradesh, Kerala, Karnataka, Gujarat, and Delhi.
Kerala has emerged as the worst-hit state, with 1,957 active cases and seven new infections reported in just the last 24 hours. Amid the surge, the state government has made Covid-19 testing mandatory for individuals showing symptoms. They have also released updated guidelines, urging the public to take all necessary precautions.

Mumbai, Pune account for 70 per cent of Covid-19 infections this year
Mumbai and Pune account for 70 per cent of the Covid-19 infections this year. A statewide analysis of 1,700 cases reported from January till June 10 this year also found that the dominating lineage in Maharashtra is the XFG variant of the SARS-CoV2 virus, which causes Covid. The Whole Genome Sequencing of 184 Covid-19 samples from across Maharashtra found that 84 samples had the XFG variant, making it the dominating lineage. The LF.7 variant was detected in 34 samples while 27 samples reported the JN.1 variant. The NB.1.8.1 variant was found in one sample from a 29-year-old woman in Pune, who had previously travelled to Hyderabad on May 16 and later had symptoms like fever, sore throat, headache and stomach pain. Her sample was collected on May 26 and sent for genome sequencing, according to state health authorities. Overall, a total of 18,885 suspected samples were tested this year of which 1,700 were Covid-19 positive. Of these, 753 Covid cases were reported from Mumbai and 443 from Pune and the Covid positivity rate stands at 9 per cent. The maximum number of cases were reported in May (742) and June (951). Presently, 105 patients have been hospitalised of which 34 are from Pune, 22 from Navi Mumbai, 15 from Mumbai and 11 from Thane. Fifteen persons require intensive care while one is on ventilator support. A total of 21 deaths have been reported. As per the report a total of 1,064 persons have recovered. Meanwhile, of the 1,700 cases, an equal number of men and women had the infection while an age-wise analysis found that 291 persons are in the age group 21 to 30 years, 360 in the 31-40 age group, 262 in the 41 to 50 age group and 190 in the 51 to 60 age group. There were 208 persons in the 61-70 years age group, who had Covid infection, while 170 were in the 71-80 age group. Since 2020, Maharashtra reported over 81.80 lakh cases and 1.48 lakh deaths. The state authorities conducted a review of the Covid situation and as per the report since 2020, Maharashtra has reported a total of 81,80,064 Covid cases and 148,623 deaths. Last year there were 5,528 Covid cases and 35 deaths while in 2023 Maharashtra had reported 36,173 cases and 137 deaths. A mock drill of the state's preparedness to deal with Covid cases also indicated that there were 2572 ventilator supported beds, 3781 ICU beds, 13871 oxygen supported beds and 9658 beds without oxygen support.

KGMU doctor, MBBS student among 8 test positive for Covid
Lucknow: A resident doctor and an MBBS student at KGMU were among 8 who tested positive for Covid-19 in city on Wednesday taking the tally to 22 so far. The new cases bring Lucknow's active caseload to 17, with a total of 22 individuals contracting the virus in the recent past, five of whom have recovered. The senior resident doctor from the gynaecology oncology department, whose report came positive on Tuesday, experienced symptoms like fever, cold, cough, and body ache since last Friday. Following the diagnosis, the doctor reportedly returned to home district in Lakhimpur Kheri. An MBBS third-year student also tested positive. KGMU spokesperson Dr Sudhir Singh said both patients exhibit mild symptoms and their condition is stable. They have been isolated and prescribed necessary precautions and medication. The MBBS student, residing in the hostel, has been isolated within the premises. Also, a 61-year-old resident of Mayur Vihar Colony in Indiranagar tested positive. The elderly patient, who has no travel history, suffers from a severe heart condition with 50% coronary artery blockage. While currently in home isolation, doctors recommended hospitalisation due to underlying health issues. A health department official said: "All the patients found positive are currently in home isolation and stable."
