With the monsoon retreating, Delhi and its surrounding cities are witnessing a worrying rise in viral illnesses. Residents across Delhi, Gurugram, Noida, Faridabad, and Ghaziabad are reporting persistent fevers, cough, cold, and respiratory problems linked to flu-like infections.
A LocalCircles survey, which gathered inputs from over 11,000 citizens, revealed that 69% of households currently have one or more members unwell with Covid-like, flu, or viral fever symptoms. Alarmingly, 37% of respondents said four or more people in their families were sick, while just 25% said their homes were unaffected.
This marks a sharp increase compared to March 2025, when 54% of households reported similar illnesses. The September data indicates that nearly seven out of ten families are struggling with one or more cases this season.
Doctors say the H3N2 influenza A virus appears to be the primary cause. Unlike regular flu, which usually subsides in under a week, patients this season are taking up to 10 days to recover. Hospitals are reporting more cases of complications such as pneumonia, bronchitis, and breathing difficulties. Many patients also complain that basic over-the-counter medication, like paracetamol, is offering little relief.
Healthcare professionals warn that children, elderly citizens, and individuals with chronic health conditions — such as asthma, diabetes, COPD, or heart disease — are especially at risk. Alongside respiratory issues, some patients are also experiencing gastrointestinal problems, including nausea, vomiting, and diarrhea.
Public health experts have urged authorities to investigate the underlying triggers, pointing to factors such as stagnant water, contaminated food and water supplies, and sudden weather shifts.
With nearly 70% of households affected, Delhi-NCR is facing one of its most severe waves of seasonal viral illness in months. Doctors are advising residents to focus on preventive care, seek timely medical attention, and avoid self-medication during this outbreak.
