Delhi-NCR is currently experiencing a surge in respiratory illnesses, with the Influenza A (H3N2) virus emerging as a significant contributor. This increase marks a notable escalation compared to earlier in the year, causing concern among health officials and the public. Alongside H3N2, other respiratory viruses are also co-circulating, complicating the situation.

The H3N2 strain is causing more severe symptoms than typical seasonal flu, leading to longer fevers and increased hospitalizations. Patients are experiencing high-grade fever, chest congestion, persistent cough, sore throat, body aches, headaches, and extreme fatigue. Unlike the common cold, which usually resolves within 3 to 5 days, H3N2 can linger for a week or even longer, potentially leading to complications such as lung infections and pneumonia. The severity of the symptoms has rendered regular medications like paracetamol ineffective for many.

A recent survey of over 11,000 households in Delhi-NCR revealed that 69% reported at least one member displaying flu-like symptoms. This widespread impact highlights the pressing public health concern posed by the current outbreak. Hospital admissions are rising across Delhi, Gurugram, Noida, and Faridabad. Children, the elderly, and individuals with pre-existing respiratory problems appear to be particularly vulnerable to this strain.

The rise in H3N2 cases can be attributed to several factors, including post-monsoon waterlogging, fluctuating temperatures, and increased outdoor activities. The H3N2 virus is a subtype of the influenza A virus.

To prevent the spread of the H3N2 virus, health experts recommend several precautions:

• Vaccination: Annual flu shots are the first line of defense, reducing the severity and duration of the illness.
• Early Symptom Detection: Recognizing symptoms early can help in seeking timely medical attention and preventing complications.
• Hygiene Practices: Regular hand washing, covering coughs and sneezes, and avoiding touching the face can help minimize the spread of the virus.
• Social Distancing: When feeling unwell, it is advisable to stay home and avoid close contact with others to prevent further transmission.
• Consulting a Doctor: Individuals with co-morbidities should consult a doctor at the first sign of symptoms. Medical attention is also advised if a fever lasts over three days or is accompanied by breathlessness.

While there is no need to panic, taking these preventive steps is crucial to protect oneself and the community from the spread of the H3N2 virus and other respiratory illnesses. Staying informed and adhering to public health guidelines can help mitigate the impact of the current surge in Delhi-NCR.
