Delhi-NCR Faces Influenza A (H3N2) Surge: Health Alert Issued

The Delhi National Capital Region (NCR) is currently experiencing a significant surge in cases of Influenza A (H3N2), prompting health officials to issue warnings about the potential risks associated with this respiratory virus. The rise in infections has resulted in symptoms such as high fever, persistent cough, and severe fatigue, affecting a considerable number of residents, particularly children.

Health Officials Raise Concerns

Healthcare professionals have noted that more than 50% of children visiting outpatient departments in Delhi-NCR are exhibiting flu-like symptoms. The symptoms associated with this outbreak are reported to be severe, with many patients experiencing high-grade fevers lasting longer than 10 days. Despite the alarming symptoms, hospitalizations have not significantly increased, as most cases are mild and self-limiting.

This year, the flu season is characterized by a distinct pattern, marked by the concurrent circulation of multiple respiratory viruses, including not only Influenza A (H3N2), but also Metapneumovirus and Coronaviruses. According to Arjun Dang, CEO of Dr. Dang’s Lab, the current wave is influenced by environmental factors such as fluctuating humidity, cooler temperatures, and rising air pollution, which have led to increased indoor crowding.

Understanding Influenza A (H3N2)

Influenza A (H3N2) is a viral infection that primarily affects the respiratory system. Typical symptoms include high fever, chills, cough, sore throat, runny nose, headache, and muscle aches. While many cases resolve independently within a week, severe complications can arise, including pneumonia and respiratory failure. Health experts emphasize the importance of seeking medical attention for those exhibiting severe symptoms, especially a sudden onset of high fever.

Dr. Dhiren Gupta, a pediatric specialist at Sir Ganga Ram Hospital, further highlights the importance of vigilance during this period. He notes the increasing number of cases and the necessity for parents to monitor their children closely for the onset of symptoms. The co-circulation of various respiratory viruses suggests a potential for co-infections, which can complicate treatment and recovery.

As the situation unfolds, health authorities continue to monitor the rise of Influenza A (H3N2) alongside the ongoing concern regarding the highly contagious Nipah virus. Residents are advised to remain alert and seek prompt medical assistance if they experience any symptoms associated with the flu.
