BackgroundDengue is a viral disease whose clinical spectrum ranges from unapparent to severe forms and fatal outcomes. Although dengue death is 99 % avoidable, every year around 20,000 deaths are estimated to occur in more than 100 countries. We consider that, along with biological factors, social determinants of health (SDHs) are related to dengue deaths as well.MethodsA scoping review was conducted to explore what has been written about the role of SDHs in dengue mortality. The inclusion criteria were that documents (grey or peer-reviewed) had to include information about dengue fatal cases in humans and be published between 1997 and 2013 and written in English, Spanish, Portuguese or French. The search was conducted using a set of key words related to dengue mortality in several electronic databases: PubMed, LILACS, COCHRANE, Scielo, Science Direct, WHOLIS, OpenGrey, OpenSingle and Google Scholar. Information on SDHs was categorized under individual, social and environmental, and health systems dimensions. A summative content analysis using QDA Miner was conducted to assess the frequency of information on SDHs and its contextual meaning in the reviewed literature. The role of each SDH in dengue mortality was assessed using content analysis results.ResultsFrom a total of 971 documents retrieved, 78 met the criteria. Those documents were published in the Americas region (50.0 %), Asia (38.4 %), Europe (9.0 %) and Africa (2.6 %). The described SDHs related to dengue deaths included, in the individual dimension: age, ethnicity, education, type of infection and immunological status; and in the social dimension: poverty and care-seeking behavior. The health systems dimension included access, opportunity, and quality of care, as well as health staff knowledge. Ethnicity was considered a determinant that depends on cultural and socioeconomic conditions.ConclusionsAlong with biological factors, there are several SDHs related to dengue mortality. However, only a few of these have been systematically analyzed, suggesting the need for more studies on this subject to inform the design and implementation of sustainable interventions to decrease dengue mortality. These findings nevertheless provide a better understanding of the non-biological factors involved in dengue mortality.Electronic supplementary materialThe online version of this article (doi:10.1186/s12879-015-1058-x) contains supplementary material, which is available to authorized users.

“…Over 1.7 million cases were reported across America and the Caribbean [ 61 , 62 ]. Two main factors may have enhanced virus transmission in the northern Caribbean Sea, one may have been low population immunity against the circulating serotype (types 1 and 4), as in the French West Indies [ 62 ], and climatic conditions. 2010 was one of the warmest years since 1850 in San Juan [ 63 ] and in the Caribbean Sea in general (SST 1 °C above the average between 1978–2012).…”

We test the hypothesis that climate and environmental conditions are becoming favorable for dengue transmission in San Juan, Puerto Rico. Sea Level Pressure (SLP), Mean Sea Level (MSL), Wind, Sea Surface Temperature (SST), Air Surface Temperature (AST), Rainfall, and confirmed dengue cases were analyzed. We evaluated the dengue incidence and environmental data with Principal Component Analysis, Pearson correlation coefficient, Mann-Kendall trend test and logistic regressions. Results indicated that dry days are increasing and wet days are decreasing. MSL is increasing, posing higher risk of dengue as the perimeter of the San Juan Bay estuary expands and shorelines move inland. Warming is evident with both SST and AST. Maximum and minimum air surface temperature extremes have increased. Between 1992 and 2011, dengue transmission increased by a factor of 3.4 (95% CI: 1.9–6.1) for each 1 °C increase in SST. For the period 2007–2011 alone, dengue incidence reached a factor of 5.2 (95% CI: 1.9–13.9) for each 1 °C increase in SST. Teenagers are consistently the age group that suffers the most infections in San Juan. Results help understand possible impacts of different climate change scenarios in planning for social adaptation and public health interventions.

“…Both peaks in this study were caused by increases in the numbers of people returning from Asia, the Americas, and Africa, and probably resulted from a combination of a higher rate of local transmission at travel destinations and choice of travel destination and season. Examples are the high numbers of cases after travel to the French West Indies, which was hit by its largest outbreak ever in 2010 [26], and to Suriname in 2012 (http://www.paho.org/hq/index.php? option=com_docman&task=doc_view&gid=17247&Itemid=).…”

During 12 years of surveillance in Belgium, dengue virus (DENV) infection was diagnosed in 676 of 7771 (8.7%) returning travellers by the use of ELISA, RT-PCR, and/or antigen detection. Men and women were equally infected. The mean age of the patients was 36.78 years (range, 3-77 years). Most of the infections occurred after a stay in Asia (55.9%), followed by the Americas (31.8%), Africa (7.2%), Oceania (1.0%), and Europe (0.4%). The number of patients coming from Africa increased as of 2009, to reach a proportion of 17% in 2011. The most prevalent serotype was DENV-1, followed by DENV-2, DENV-3, and DENV-4. Two remarkable increases in dengue incidence were noticed in 2010 and 2013.
