Comparison of the h-Index Scores Among Pathogens Identified as Emerging Hazards in North America

Transbound Emerg Dis. 2016 Feb;63(1):79-91. doi: 10.1111/tbed.12221. Epub 2014 Apr 16.


Disease surveillance must assess the relative importance of pathogen hazards. Here, we use the Hirsch index (h-index) as a novel method to identify and rank infectious pathogens that are likely to be a hazard to human health in the North American region. This bibliometric index was developed to quantify an individual's scientific research output and was recently used as a proxy measure for pathogen impact. Analysis of more than 3000 infectious organisms indicated that 651 were human pathogen species that had been recorded in the North American region. The h-index of these pathogens ranged from 0 to 584. The h-index of emerging pathogens was greater than non-emerging pathogens as was the h-index of frequently pathogenic pathogens when compared to non-pathogenic pathogens. As expected, the h-index of pathogens varied over time between 1960 and 2011. We discuss how the h-index can contribute to pathogen prioritization and as an indicator of pathogen emergence.

Keywords: bibliometric; h-index; pathogen emergence; pathogen hazard; pathogen prioritization.
