“…Dengue outbreaks worldwide have progressively increased [9][10][11][12][13][14], with recent outbreaks in the North Africa and Middle East regions [1,15,16]. In recent years, bibliometric analysis has been widely conducted to evaluate scientific research activities in many fields of infectious diseases such as chikungunya [17], Ebola virus disease [18,19], influenza [20], John Cunningham virus [21], leishmaniasis [22,23], Mayaro virus fever [24], Malaria [25], yellow fever disease [26], and Zika virus [27].…”

BackgroundDengue is an important emerging and re-emerging arboviral infection globally as a rapidly growing and widespread public health problem, with transmission occurring in more than 128 countries in Asia, Americas, southeast Africa, western Pacific, and eastern Mediterranean regions. Therefore, the aim of this study was to characterize and quantify the scientific output of dengue research in Arab countries relative to that worldwide by using a bibliometric analysis.MethodsThe standardized search approach based on the use of the the keyword “dengue” in the title, abstract, and keyword field was used to get research output related to dengue at a global level. All data related to dengue were collected from the past to December 31, 2015.ResultsA total of 19,581 dengue-related documents identified in the Scopus database. The results show that the study of dengue exhibits an overall upward trend from 1872 to 2015 with peak publications in 2014. The leading countries in dengue research were the USA (4,709; 24.05 %), India (1,942; 9.92 %), Brazil (1,530; 7.81 %), Thailand (1,260; 6.43 %), the UK (1,129; 5.77 %), and France (1,087; 5.55 %). Only 226 (1.16 % of the overall global research effort in the dengue field) articles were published from the Arab region. The total number of citations for all publications was 352,710, with an average of 18.0 citations per publication. Furthermore, the h-index for all extracted data related to dengue research was 186. Kingdom of Saudi Arabia (KSA) was the most productive country in Arab region with 102 documents representing 45.1 %. Furthermore, the h-index for all extracted data related to dengue research was 27. The USA was Arab’s most main cooperative partner (46, 20.4 %), followed by India (36, 15.9 %).ConclusionsThe amount of literature related to dengue research has considerably increased over the last decade. This bibliometric analysis has demonstrated the leading role that the USA, India, Brazil, Thailand, the UK, and France play in dengue research. The Arab world produced fewer publications related to dengue with lower quality than other world countries.

“…Disease-related news articles were provided by HealthMap19, an internationally recognized, global disease alert system capturing outbreak reports from over 200,000 electronic news sources. EpiNews was evaluated on multiple outbreaks in the recent past, such as whooping cough in U.S. (2012)20, periodic outbreaks of avian influenza A(H7N9)2122 and hand, foot, and mouth disease (HFMD) in China (2013 and 2014), periodic outbreaks of acute diarrheal disease (ADD) in India (2013 and 2014), major dengue outbreaks in China (2014)23 and India (2013). Our experiments indicate that EpiNews was successfully able to capture the dynamics of the mentioned outbreaks and estimate the case counts in many of these instances before official reports were published.…”

In retrospective assessments, internet news reports have been shown to capture early reports of unknown infectious disease transmission prior to official laboratory confirmation. In general, media interest and reporting peaks and wanes during the course of an outbreak. In this study, we quantify the extent to which media interest during infectious disease outbreaks is indicative of trends of reported incidence. We introduce an approach that uses supervised temporal topic models to transform large corpora of news articles into temporal topic trends. The key advantages of this approach include: applicability to a wide range of diseases and ability to capture disease dynamics, including seasonality, abrupt peaks and troughs. We evaluated the method using data from multiple infectious disease outbreaks reported in the United States of America (U.S.), China, and India. We demonstrate that temporal topic trends extracted from disease-related news reports successfully capture the dynamics of multiple outbreaks such as whooping cough in U.S. (2012), dengue outbreaks in India (2013) and China (2014). Our observations also suggest that, when news coverage is uniform, efficient modeling of temporal topic trends using time-series regression techniques can estimate disease case counts with increased precision before official reports by health organizations.

“…However, in addition to the frequent importation of viral agents, risk factors such as the expansive distribution of Aedes albopictus Xie et al, 2013), suitable climate conditions for mosquito vector breeding, and uncontrolled urbanization contribute to the expansion of DF epidemics. These factors promote the potential for transformation of an imported epidemic to endemic (Shen et al, 2015;Chen and Han, 2016). In the past, strategies for controlling DF have focused more on coastal regions in Fujian; however, the diversity of the viral source and geographical expansion of DF suggested that it was necessary to strengthen epidemiological and etiological surveillance, not only in coastal regions but also in inland regions.…”

“…Given the high sequence identity (more than 99.3%) with the virus found in Indonesia (JF967877/ Indonesia/2009), the viral source of the local DF outbreak in 2004 (genotype I) was thought to be countries in Southeast Asia, including Indonesia. DENV1 has continually circulated in Guangdong province for at least 18 years since 1997 (Shen et al, 2015). Phylogenetic analysis revealed that DENV1 caused a large outbreak in Guangdong in 2014 and included genotypes I, IV, and V (Sun et al, 2016).…”

Dengue fever (DF) is a vector-borne disease and a tremendous socioeconomic burden on tropical and subtropical countries worldwide. To explore the characteristics of DF epidemic in the Fujian province, information of DF cases in Fujian during 2004-2014 was collected and analyzed. The complete E genes of 48 viral isolates were amplified and sequenced for phylogenetic analysis. A total of 733 cases was reported, of which 612 (83.5%) occurred during the peak period from August to October. Additionally, 76% (190/250) of imported cases originated from Southeast Asia countries, by the epidemiological investigation. Phylogenetic analysis of the 48 viral isolates revealed that three genotypes (I, IV, V) of DENV1, and one genotype each of DENV2 (cosmopolitan) and DENV3 (I) circulated in Fujian during [2004][2005][2006][2007][2008][2009][2010][2011][2012][2013][2014]. Similar to the results of the epidemiological investigations, the source of most of the viral isolates, including imported and indigenous cases, may be Southeast Asia countries; however, importation from adjacent provinces was also observed in recent years. Overall, DF is considered an imported epidemic disease in Fujian. Increasing diversity of the viral source and geographic expansion of the area affected by DF in recent years highlights the necessity for strengthening surveillance of the DF epidemic and developing strategies for DF prevention and control in Fujian.dengue virus, E gene, phylogenetic tree, epidemiology, etiology Citation:
