NEW DELHI: Transmission of the deadly H1N1 swine flu virus was the fastest in the national capital, while the infection was most fatal in Maharashtra.
The first-of-its-kind analysis to understand the transmission dynamics of the pandemic influenza that hit India has found that the doubling time (time span in which the number of people infected doubled) was the lowest in Delhi (8.89 days), and highest in Rajasthan (25.67 days).
The doubling time was as low as 9.12 days in Tamil Nadu and 9.24 days in Maharashtra, two of the states worst-hit by the flu.
When it comes to basic reproduction figures in a susceptible population, the number of secondary cases generated by one primary case, Delhi topped the list with 1.52, followed by Tamil Nadu (1.50) and Maharashtra (1.49). The corresponding figure for Kerala stood at 1.35, Haryana (1.33), Karnataka (1.32) and Rajasthan (1.17).
Delhi recorded the highest number of H1N1infections in 2009-10 at 9,697 positive cases, followed by Maharashtra (6,283) and Rajasthan (3,380).
However, when it comes to case fatality proportion (CFP), the number of people who die per 100 infected cases, Maharashtra was way ahead with a CFP of 7.34, followed by Karnataka (6.98) and Rajasthan (5.86).
Though Delhi recorded higher number of cases and a higher percentage of infections at 30.38%, its case fatality rate stood at 0.98 per 100 cases. Tamil Nadu's case fatality rate was the lowest at 0.34.
This analysis by Dr Gani Shrishail Raamappa, assistant professor at Karnataka University and his team, has been published by the journal Current Science.
