Understanding the Current H3N2 Flu Surge in India
Hospitals in Delhi report a significant rise in flu cases over recent weeks. Patients present with typical H3N2 flu symptoms like high fever, cough, sore throat, body ache, headache, and weakness. While many cases are mild, doctors observe that recovery takes longer than usual. Consequently, a small percentage of patients require hospitalisation, according to a TOI report.
Dr. Suranjeet Chatterjee, senior consultant, Internal Medicine, Apollo Hospital, notes that recovery duration varies. Although many individuals recover within 3 to 5 days, some cases may extend to 7 days or more, particularly when complications arise. Furthermore, about 2–5% of cases necessitate hospitalisation, mainly among the elderly or those with comorbidities. Even after recovery, many patients experience a lingering cough, weakness, and reduced appetite.
Recognising H3N2 Flu Symptoms
At Max Super Speciality Hospital, Saket, the increase in flu cases is equally visible. Over the past two weeks, more than half of the patients visiting the OPD with fever have exhibited flu-like symptoms. Dr. Rommel Tickoo, director, Internal Medicine, states that H3N2 appears to be the predominant strain. Patients frequently present with a high-grade fever unresponsive to paracetamol, along with throat pain, cough, headache, and body ache. Moreover, while most patients recover within 5–7 days, a significant number develop bronchitis, leading to a persistent cough. A few also progress to serious complications such as pneumonia, which often requires hospital care. Lingering fatigue and loss of appetite are common even post-recovery. [2, 3, 6, 7]
The same trend is also reported at Sri Balaji Action Medical Institute. Dr. Arvind Aggarwal, senior consultant, Internal Medicine, mentions treating approximately 15–18 flu patients daily. Most of these patients exhibit high fever, sore throat, body ache, cough, nasal and chest congestion, and occasionally gastrointestinal infections. Importantly, this year’s flu appears more severe. Many patients continue to experience a persistent cough and fatigue even after their fever subsides. Most recover within 5–7 days with medication and home remedies, but weakness and cough might linger for up to two weeks. A small fraction—especially the elderly, young children, and those with pre-existing heart or lung disease—may develop severe symptoms such as breathlessness or bluish lips and nails, necessitating hospitalisation.
Prevention and Management of H3N2 Influenza
Doctors suggest that the current surge aligns with seasonal flu patterns during the monsoon season. They advise timely medical consultation, adequate rest, and proper hydration to manage H3N2 flu symptoms effectively. Extra caution is imperative for vulnerable groups to mitigate the risk of complications. Considering this, Dr. Tickoo emphasises prevention, strongly recommending annual flu vaccination for everyone, particularly those at higher risk, to reduce the severity and spread of influenza.

To prevent transmission, maintaining good hygiene is vital. This includes frequent hand washing, avoiding touching the face, and covering coughs and sneezes. Furthermore, avoiding crowded places and wearing masks in public can reduce exposure. If symptoms appear, it is crucial to consult a doctor promptly; self-medication, particularly with antibiotics, is not advisable unless a secondary bacterial infection is confirmed. Antiviral medications like oseltamivir can be effective if started within 48 hours of symptom onset, especially for high-risk individuals.
