Abstract

Influenza A (H1N1) caused significant mortality and morbidity globally. We identified the hotspots for H1N1 influenza in India using cases and deaths reported in the Integrated Disease Surveillance Program between 2010 and 2017. A total of 114,667 cases and 8543 deaths were reported from across India, at an overall case fatality rate of 7.5%. While Maharashtra accounted for 21% of cases and 31% of deaths, Delhi and Gujarat were ranked the highest based on the population-adjusted ranks for morbidity and mortality, respectively. The current analysis identified states and union territories in western India (Delhi, Punjab, Rajasthan, Gujarat and Maharashtra) to be especially vulnerable.

Keywords: H1N1; India; influenza hotspots; pandemic.

Heat map of India showing States and Union Territories of India vulnerable to H1N1 influenza. States and Union Territories which have a lower rank, and hence a higher vulnerability to H1N1 influenza, have been shown in red, and those with a higher rank, indicating a lower vulnerability to H1N1 influenza have been shown in light blue. States and Union Territories with intermediate vulnerability has been shown in decreasing shades of blue. Vulnerability was computed as the average of the mean rank for reported cases and reported deaths over the eight-year period (2010–2017).
