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.<\/jats:p>","DOI":"10.1177\/0049475519879357","type":"journal-article","created":{"date-parts":[[2019,11,27]],"date-time":"2019-11-27T01:24:24Z","timestamp":1574817864000},"page":"166-169","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":14,"title":["Hotspots of H1N1 influenza in India: analysis of reported cases and deaths (2010\u20132017)"],"prefix":"10.1177","volume":"50","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6443-608X","authenticated-orcid":false,"given":"Pranab","family":"Chatterjee","sequence":"first","affiliation":[{"name":"Public Health Specialist, Translational Global Health Policy Research Cell, Indian Council of Medical Research Scientist B, Indian Council of Medical Research, National Institute of Cholera and Enteric Diseases, Kolkata, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bhavna","family":"Seth","sequence":"additional","affiliation":[{"name":"Fellow, Department of Pulmonary and Critical Care Medicine, Johns Hopkins University, Baltimore, MD, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tamoghna","family":"Biswas","sequence":"additional","affiliation":[{"name":"Pediatrics Consultant and Independent Researcher, Kolkata, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2019,11,26]]},"reference":[{"key":"bibr1-0049475519879357","unstructured":"Chan M.
