H3N2 Flu Strain Hits 69% of Delhi NCR Households: Experts Advise Caution

New Delhi | September 23, 2025 A surge in the H3N2 virus, a subtype of Influenza A, has been reported across Delhi NCR, with a recent survey indicating that 69% of households currently have one or more members experiencing flu-like symptoms. Medical experts warn that the strain spreads rapidly, particularly during weather changes and periods of reduced immunity. Dr. Manjusha Agarwal, senior consultant at Gleneagles Hospital, Mumbai, noted that early symptoms often resemble a common cold but can worsen without timely care. Fever, sore throat, runny nose, cough, body aches, headache, and fatigue are common signs. Complications may include pneumonia, bronchitis, or aggravation of pre-existing heart and lung conditions. Severe symptoms such as chest pain, breathing difficulties, bluish lips, confusion, or dehydration require immediate medical attention. Children, the elderly, pregnant women, and individuals with chronic health issues like diabetes, asthma, or heart disease are at higher risk. In children, additional symptoms like nausea, vomiting, or diarrhea may appear. Diagnosis typically involves clinical evaluation, though physicians may use throat swabs or rapid influenza diagnostic tests for confirmation. There is no specific cure for H3N2. Treatment focuses on rest, hydration, and medications to relieve fever and discomfort. Antiviral therapy may be prescribed for high-risk or severe cases. Experts emphasize that self-medicating is discouraged; patients should follow medical advice closely to ensure safe recovery. Preventive measures are critical to controlling H3N2 spread. Frequent handwashing, mask use in public spaces, maintaining social distance from sick individuals, and strengthening immunity through proper diet and sleep are recommended. Seasonal influenza vaccination is also advised, especially for vulnerable populations. Timely recognition of symptoms, medical care, and good hygiene practices can reduce complications and speed recovery. Experts urge residents to monitor their health closely and seek professional advice if symptoms persist beyond a few days. Public health officials continue to monitor the virus’s spread and stress that awareness, early care, and preventive measures remain the most effective tools in combating H3N2 during the current flu season. Consultation with healthcare providers is essential before starting any medication or home treatment. Following professional guidance can prevent escalation of symptoms and protect both individual and community health.
