Abstract
BackgroundA number of scientific papers on yellow fever have been published but no broad scientometric analysis on the published research of yellow fever has been reported.The aim of the article based study was to provide an in-depth evaluation of the yellow fever field using large-scale data analysis and employment of bibliometric indicators of production and quantity.MethodsData were retrieved from the Web of Science database (WoS) and analyzed as part of the NewQis platform. Then data were extracted from each file, transferred to databases and visualized as diagrams. Partially by means of density-equalizing mapping makes the findings clear and emphasizes the output of the analysis.ResultsIn the study period from 1900 to 2012 a total of 5,053 yellow fever-associated items were published by 79 countries. The United States (USA) having the highest publication rate at 42% (n = 751) followed by far from Brazil (n = 203), France (n = 149) and the United Kingdom (n = 113). The most productive journals are the “Public Health Reports”, the “American Journal of Tropical Medicine and Hygiene” and the “Journal of Virology”. The gender analysis showed an overall steady increase of female authorship from 1950 to 2011. Brazil is the only country of the five most productive countries with a higher proportion of female scientists.ConclusionsThe present data shows an increase in research productivity over the entire study period, in particular an increase of female scientists. Brazil shows a majority of female authors, a fact that is confirmed by other studies.
Highlights
A number of scientific papers on yellow fever have been published but no broad scientometric analysis on the published research of yellow fever has been reported
Moreno and Barata [3] demonstrated that outbreaks of yellow fever have occurred in regions of Brazil where no reports had been registered for decades [3,4]
Total numbers of published items The present study outlines a scientometric analysis of the scientific publications on yellow fever during the research timeframe from 1900 to 2012
Summary
A number of scientific papers on yellow fever have been published but no broad scientometric analysis on the published research of yellow fever has been reported. The vast majority of reported cases and deaths occur in tropical areas like Sub-Saharan Africa (about 90%) and to a lesser extent in Central and South America. According to WHO there are an estimated 200,000 cases of yellow fever causing 30,000 deaths annually worldwide with 90% occurring in Africa. These global estimates of yellow fever disease stem from the 1990s [5,6,7]. A recent analysis of African data sources due to be published later this year estimates similar figures for 1995, for the year 2013 approximately 84,000 to 170,000 cases and 29,000 to 60,000 deaths of yellow fever [8]
