India's H3N2 Surge: Toxic Air, Low Vax Rates Drive Winter Crisis

• India is experiencing a significant surge in H3N2 influenza cases this winter.
• The H3N2 surge is fueled by high air pollution, low vaccination rates, and reduced immunity post-Covid.
• Air pollution exacerbates H3N2 symptoms, leading to prolonged cough, breathlessness, and increased complications like pneumonia.
• The current H3N2 wave is characterized by longer-lasting symptoms and deeper respiratory involvement compared to typical seasonal flu.
• High-risk individuals should prioritize vaccination, avoid pollution, and seek early medical care for symptoms.

Why It Matters: Toxic air and low vaccination fuel India's severe H3N2 surge, straining health systems.
