India’s COVID-19 Landscape Shifts With Emergence of NB.1.8.1 and LF.7 Subvariants
BENGALURU, May 26, 2025 — In a concerning development, 2 new COVID variants detected in India have reignited public health concerns, as Karnataka reported the first COVID-19 death of 2025. The rising number of mild infections and the appearance of two new subvariants—NB.1.8.1 and LF.7—has led to swift health advisories in several states, including Karnataka, Delhi, and West Bengal.
2 New COVID Variants Detected in India: What We Know
The 2 new COVID variants detected in India, NB.1.8.1 and LF.7, were recently flagged by India’s SARS-CoV-2 Genomics Consortium (INSACOG). The World Health Organization (WHO) has classified both as “Variants Under Monitoring,” indicating low global health risk but warranting close observation.
NB.1.8.1, in particular, carries spike protein mutations—A435S, V445H, and T478I—that could potentially boost transmissibility and allow partial immune escape. However, current data suggests that the 2 new COVID variants detected in India do not lead to more severe illness or increased mortality compared to existing strains.
Health Ministry Confirms Low Severity
As of May 25, 2025, India has recorded 275 active COVID-19 cases, most of which are mild and being treated at home. The Union Health Ministry has emphasized that there is no cause for panic, but citizens are advised to remain cautious. The 2 new COVID variants detected in India have not shown a higher rate of hospitalization or death so far.
Officials noted that the fatality reported in Karnataka was an isolated case involving a senior citizen with comorbidities, and investigations are ongoing to determine if it was directly linked to one of the 2 new COVID variants detected in India.
States Respond Swiftly to 2 New COVID Variants Detected in India
Karnataka, Delhi, and West Bengal have already issued advisories urging citizens to follow basic preventive measures. Mask-wearing in crowded areas, hand hygiene, and avoiding unnecessary travel have been recommended. Health departments are also ramping up genomic surveillance to track the spread of the 2 new COVID variants detected in India.
While public health officials have downplayed the severity, they are urging higher vigilance due to the unpredictable nature of viral evolution. The presence of 2 new COVID variants detected in India serves as a reminder that the virus has not yet vanished.
Experts Weigh In on the Variants
Virologists and epidemiologists stress that although the 2 new COVID variants detected in India are not currently classified as threats, their mutations deserve close monitoring. “The A435S and T478I mutations found in NB.1.8.1 are similar to those seen in past variants known for increased transmission,” said Dr. Meera Bansal, a virologist based in New Delhi. “But without evidence of higher severity or immune escape, we are cautiously optimistic.”
Dr. Rakesh Iyer from Bengaluru’s Victoria Hospital added, “The good news is that vaccine efficacy seems to hold up against these 2 new COVID variants detected in India, at least for now. But that could change, so we must be proactive, not reactive.”
Public Urged to Stay Calm and Informed
Government agencies and healthcare professionals continue to monitor the evolving situation. Citizens are urged not to fall prey to misinformation or panic buying. While the 2 new COVID variants detected in India are under scientific scrutiny, current health infrastructure is fully equipped to manage the situation.
Vaccination campaigns are ongoing, and booster doses are being encouraged, especially for vulnerable populations. As part of its strategy, the health ministry is also focusing on increasing RT-PCR testing and wastewater surveillance to stay ahead of the curve.
Conclusion
The 2 new COVID variants detected in India, NB.1.8.1 and LF.7, mark a new chapter in the pandemic journey, albeit a less severe one so far. While Karnataka's first COVID-related death in 2025 is a sobering reminder of the virus’s lingering presence, the overall situation remains under control. Continued vigilance, responsible behavior, and science-backed policymaking will be crucial in navigating this next phase.
Stay safe, stay informed, and follow official guidelines as India adapts to the emergence of the 2 new COVID variants detected in India.
