Fatalities Associated with the 2009 H1N1 Influenza A Virus in New York City

Abstract: BACKGROUND. When the 2009 H1N1 influenza A virus emerged in the United States, epidemiologic and clinical information about severe and fatal cases was limited. We report the first 47 fatal cases of 2009 H1N1 influenza in New York City. METHODS. The New York City Department of Health and Mental Hygiene conducted enhanced surveillance for hospitalizations and deaths associated with 2009 H1N1 influenza A virus. We collected basic demographic and clinical information for all patients who died and compared abstract… Show more

“…Limitations aside, this analysis demonstrates an association between NAI supply and H1N1 mortality during the 2009 influenza pandemic at an ecological level consistent with other findings on the individual level 3, 10, 14. This effect does not seem large on a population level and equates to a drop in mortality in the Americas from the observed 1·18 per 100 000 to 1·16 per 100 000 for a 10% increase kg of oseltamivir/100 000.…”

“…Various observational studies have provided evidence of improved survival with prompt antiviral treatment within 48 hours of influenza symptom onset, however not all studies have found this clear benefit 8, 9, 10, 11. The purpose of this ecological analysis was, therefore, to examine the relationship of mortality specific to pandemic H1N1 influenza and NAI supply at the level of WHO Member States and provide further evidence of the aggregate role that NAIs may play in reducing influenza mortality in future pandemics.…”

“…It was also notable that younger people were affected with severe pneumonia, which was fatal in some cases. 8,9 A total of 198 fatal cases with laboratory-confirmed 2009 H1N1 virus infection were reported by the Japanese Ministry of Health, Labour and Welfare, between August 2009 and March 2010. The fatality rate was estimated to be 0.001%, which was much lower than that reported in other countries.…”

“…After screening 787 titles and abstracts and 164 full‐text articles, 48 cohort studies plus 14 companion reports met eligibility criteria and were included 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73. These studies examined H1N1 between March 1, 2009 and October 24, 2010, and the most common factor of social disadvantage reported was ethnic minority status (36/48 studies), except in 12 studies that considered H1N1‐infected patients from LIC/LMIC, which were analyzed separately for each country (one study from Guatemala,57 two from Morocco,60, 61 one from Pakistan,73 and eight from India, plus four companion reports) 60, …”

“…Exceptions were that 10 studies did not use a representative sample15, 24, 30, 36, 38, 42, 51, 62, 72 and four studies included patients who were severely ill, hospitalized, or dead at the beginning of the study. In addition, only 13 studies controlled for comorbidities17, 24, 27, 34, 36, 41, 42, 49, 51, 53, 54, 56 and 18 studies did not report their follow‐up rate or had a withdrawal rate of 10% or greater 16, 17, 24, 38, 41, 49, 51, 53, 55, 58, 60, 61, 62, 65, 66, 72, 73…”
