COVID Variants: India Detects Two New Subvariants Amid Rising Cases
India detects two new COVID variants—NB.1.8.1 and LF.7—amid rising cases. Health authorities urge caution while monitoring the evolving situation.
COVID Variants Update: Two New Subvariants Detected in India as Cases Rise, Health Ministry Issues Advisory
Currently, India is experiencing a careful increase in COVID-19 cases starting May 25, 2025. The nation has reported 275 active infections across its states, and health authorities are on high alert. States such as Karnataka, Delhi, and West Bengal have issued health advisories and are also advising people against panic. Most infections are mild and treated with at-home isolation. Even though numbers are quite modest in comparison to the previous waves, public health officials maintain that vigilance and precautionary measures must remain in the foreground for proper execution of virus management.
In this light, some new implications for India’s pandemic path have come from discovering two new COVID variants, namely NB.1.8.1 and LF.7. Scientists from the Indian SARS-CoV-2 Genomics Consortium or INSACOG identified these subvariants and WHO does not classify these variants under “Variants of Concern” and “Variants of Interest.” As such, these variants are classified as “Variants Under Monitoring” in which currently have no major global health threat but need to be observed for potential transmissibility.

Among the two, NB.1.8.1 is of special interest because of its spike protein mutations: A435S, V445H, and T478I. These modifications might increase the virus’s ability to proliferate and possibly avoid some degree of the immune protection mechanism. However, the WHO was clear that there is no evidence at present that this form causes a more serious disease than previous ones, or spurs a higher mortality rate.
At present, the strain JN.1 is continuing as the primary strain in India, comprising roughly 53% of all newly occurring infections. Very likely, this means that those newer variants that are under monitoring are not yet widely spreading or leading the count of cases.
India reported two deaths recently from COVID-19 in the general rise of cases. This thus reminds us that the virus can still kill, especially among the vulnerable. A 21-year-old from Maharashtra died after being admitted to Chhatrapati Shivaji Maharaj Kalwa Hospital in Thane on May 22. Earlier, an 84-year-old man died of COVID-related multi-organ failure in Bengaluru. These have stirred fresh people jitters though both had high-risk health conditions.
Health departments in different states have also put out advisories to reinforce standard precautions among the citizenry. Common precautions include wearing masks in crowded spaces, sanitizing hands regularly, getting booster shots, and keeping away from unimportant travel. In addition, citizens are advised not to panic or fall to ungrounded rumors on the new variants as they have not caused a sudden increase in severe illness.
The Union Health Ministry is still cooperating with the genome sequencing body INSACOG in tracking mutation and hence, early detection of attitude changes of the virus. Their findings assist in guiding policy making and healthcare readiness at the national level.
This detection of two new COVID variants—NB.1.8.1 and LF.7—illustrates that the virus continues to evolve, but at the moment, it should not raise any alarm. India can effectively manage the current phase of the pandemic if the public is educated to take proper precautions, continuously updated, and behaves responsibly toward the public. The government is also committed to transparency and rapid response, ensuring that any emerging threat is dealt with through timely measures and adequate healthcare resources.
