New Delhi: A fast-spreading respiratory illness, dubbed the ‘Mystery Flu’, is gripping Delhi and its surrounding cities, with 69% of households in Delhi, Noida, Gurugram, and Ghaziabad reporting at least one family member down with flu-like symptoms, according to a recent survey.
Health experts have now identified the primary culprit as the H3N2 influenza virus, a strain of Influenza A known for its high transmission rate and lingering effects. What sets it apart from typical seasonal flu is its sudden onset and prolonged recovery period, often affecting even healthy individuals for weeks.
Medical professionals report a sharp increase in cases from schools, hostels, and densely populated workplaces, where the virus spreads rapidly through droplets from coughing, sneezing, or close contact.
Commonly reported symptoms include high fever with chills, persistent dry cough, sore throat, body aches, headaches, extreme fatigue, and in more serious cases, difficulty in breathing. Doctors warn that while many recover within a week, the cough can linger for two to three weeks.
Those at higher risk include senior citizens, young children, pregnant women, and people with pre-existing conditions like diabetes, heart disease, or chronic respiratory illnesses.
The Indian Council of Medical Research (ICMR) has issued a set of advisories to manage and contain the outbreak. Rest, hydration, and symptomatic treatment remain the first line of defence for mild cases. In more severe cases or among vulnerable groups, antivirals such as Oseltamivir may be prescribed — but only if taken within 48 hours of symptom onset. Experts strongly discourage the use of antibiotics, which are ineffective against viral infections.
Preventive measures remain crucial. Doctors urge people to wear masks in crowded spaces, practice frequent handwashing, and self-isolate at the first sign of illness to prevent further spread.
With cases climbing steadily across the National Capital Region, health authorities are closely monitoring the situation. Citizens are advised to remain alert, avoid self-medication, and seek medical advice if symptoms worsen.
