2009 pandemic influenza in India

Indian Pediatr. 2010 Jan;47(1):25-31. doi: 10.1007/s13312-010-0007-4.


Pandemic-09-H1N1 virus caused the pandemic starting in the second quarter of 2009. The world was prepared to face the pandemic since it was anticipated for over one decade. Most countries, including India, had made detailed pandemic preparedness plans well ahead of its actual occurrence. The infection rapidly spread to the whole country within 2-3 months. The national tactics were to slow down its importation through international air travelers and to slow down its spread in cities and major towns. More than 75% of all infected persons were urban dwellers, suggesting that efforts were concentrated in urban communities. In general the illness of pandemic influenza has been similar to endemic/seasonal influenza; however, there is insufficient epidemiological and clinical data on the latter. We hope that the unprecedented experience of managing the pandemic will encourage the Government of India to plan to confront endemic/seasonal influenza more systematically. The pandemic seems to have reached a peak in September/October and has been on the decline since then.
