H1N1 cases spike across the country

Across India, there has been a notable rise in H1N1 cases, accompanied by other flu-like illnesses and respiratory infections. Health experts emphasize that while the situation does not warrant alarm, children with asthma and other chronic conditions may need special care. The H1N1 virus, a subtype of influenza A, can lead to respiratory illnesses characterized by fever, cough, sore throat, runny nose, headache, fatigue, and body aches. In some instances, patients might also experience vomiting and diarrhea.

Delhi has experienced a sharp increase in H1N1 cases, with over 1,300 infections reported this monsoon season, six times more than last year at this time. Government hospitals have established separate isolation wards to handle the surge in cases. Mumbai has also witnessed a significant rise, with 309 cases reported between June and August this year, compared to 72 during the same period in 2025.

Bengaluru is witnessing a noticeable surge in respiratory illnesses among children, with doctors confirming H1N1 cases, although testing is limited to those with severe symptoms or those with severe acute respiratory illnesses. In a single school, over 500 cases of influenza-like illness have been reported, with two confirmed H1N1 cases among students, raising concerns about transmission in classrooms and other crowded indoor settings.

The Indira Gandhi Institute of Child Health has seen a steady influx of viral fever cases, with around two to three H1N1 cases confirmed daily among those tested. Private pediatricians are also reporting a sharper rise in H1N1 cases among school-going children. In Chennai, H1N1 cases among children have been reported for the past two weeks, with a slight increase this week.

Public health experts in Kerala have been urging the government to invest in annual flu vaccinations for the elderly to reduce mortality, hospitalizations, and out-of-pocket expenses.
