Summary
Around 54% of households surveyed across Delhi-NCR have at least one member experiencing flu or viral fever-like symptoms, according to a LocalCircles survey released on August 23. The findings come as Delhi records a rise in seasonal influenza and H1N1 cases, although the Indian Council of Medical Research (ICMR) has said no new H1N1 strain has been detected in the country.
Survey Shows Flu Symptoms Across Households
The LocalCircles survey collected 32,000 responses from residents of Delhi, Gurugram, Noida, Faridabad and Ghaziabad. About 69% of respondents were men and 31% were women.
The survey found that 23% of households had four or more members experiencing flu or viral fever-like symptoms. Another 16% reported two to three symptomatic members, while 15% had at least one person with such symptoms.
Overall, 39% of surveyed households had two or more members experiencing symptoms at the same time, suggesting significant transmission within households.
The capital has recorded 2,392 influenza-A cases so far this year, including 1,777 H1N1 cases. The tally also includes 37 H1 cases, 138 H3 cases and 440 other influenza cases.
The official figures, however, cover people who sought testing at hospitals or laboratories. People who experienced symptoms but recovered at home may not be reflected in the reported numbers.
ICMR Says No New H1N1 Strain Detected
Amid concerns over the rise in cases, the ICMR said on Sunday that no new strain of influenza A (H1N1) has been identified in India and urged people not to panic.
An ICMR scientist said the H1N1 viruses currently circulating in India are similar to the A/Missouri/11/2025 (H1N1) pdm09-like strain and have been circulating since 2025.

The symptoms being reported include fever, cough, sore throat, headache, body aches, chills and fatigue. ICMR described seasonal influenza as “mostly self-limiting”, with most people recovering with appropriate care and adequate rest.
However, young children, older adults and people with underlying health conditions remain at greater risk of complications.
