H3N2 influenza cases surge in Delhi-NCR: Should you be worried? Experts weigh in

Hospitals across Delhi NCR are reporting a sharp increase in patients with flu-like symptoms, identified as the H3N2 Influenza A virus. This strain is causing high-grade fever, chest congestion, a persistent cough, and fatigue that can last for over a week, unlike the common cold. Children are noted to be particularly vulnerable. Experts advise that while there is no need to panic as H3N2 is a known influenza strain, certain precautions are necessary. People with co-morbidities should consult a doctor at the first sign of symptoms. For others, medical attention is advised if a fever lasts over three days or is accompanied by breathlessness.
