ICMR says no new H1N1 strain, urges no panic

The Indian Council of Medical Research (ICMR) has reassured the public that no new strain of H1N1 has been discovered in India, and there is no need for alarm as flu cases persist across the nation, according to ANI on Sunday. Senior ICMR scientists reported that the Influenza A (H1N1) pdm09 viruses currently existing in India are part of the A/Missouri/11/2025 (H1N1) pdm09-like virus strain, belonging to clade 6B.1A.5a2a, subclade D.3.1.1, and have been circulating since 2025.

The ICMR noted that these influenza strains are well-matched with vaccine strains advised for the Northern Hemisphere. Seasonal influenza, including H1N1, typically resolves on its own and presents common symptoms like fever, cough, headache, and body ache. The clarification surfaced as Delhi experienced a surge in H1N1 cases, with the city reporting 2,602 influenza cases and 1,777 H1N1 cases by Friday, including 114 H1N1 cases on Thursday alone.

The Delhi government had advised the public to maintain respiratory hygiene, avoid crowded areas, seek prompt medical assistance, cover their mouths and noses during coughs or sneezes, frequently wash their hands, and wear masks in densely populated places. Two referral laboratories, situated at AIIMS and the National Centre for Disease Control, were designated for special surveillance.

The ICMR emphasized that young children, the elderly, and individuals with pre-existing health issues might face increased risks of complications from seasonal influenza. They advised people to seek timely medical attention if symptoms persist, worsen, or become severe. The ICMR continued to monitor the situation through regular surveillance, implementing necessary public health measures.
