Mapping the Outbreaks of Dengue and Chikungunya and Their Syndemic in India: A Comprehensive Analysis Over the Past Decade Utilizing the Data From the Integrated Disease Surveillance Programme (IDSP).
Article in Cureus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThis study examines the geographic distribution, temporal trends, and syndemic interactions between dengue and chikungunya outbreaks in India from 2014 to 2023, using data from the Integrated Disease Surveillance Programme (IDSP). Understanding trends offers critical insights to enhance public health responses to co-occurring vector-borne diseases.
objectivesThe study analyzes the trends, geographic distribution, and syndemic interactions between dengue and chikungunya. It highlights patterns, high-burden areas, and seasonal dynamics to inform public health interventions for mitigating the dual burden.
methodsThis secondary data analysis used IDSP records from January 2014 to December 2023. Temporal trends in outbreaks were analyzed, and districts were categorized by severity through spatial mapping and bivariate analysis, employing statistical quartiles to assess the co-occurrence and syndemic nature of dengue and chikungunya.
resultsDengue outbreaks increased significantly from 2014 to 2017, peaking at 175 outbreaks, followed by fluctuations until a peak of 200 outbreaks in 2023. In contrast, chikungunya outbreaks peaked in 2017 at 77 outbreaks and subsequently declined to 19 outbreaks by 2023. Geographic analysis indicated a high dengue burden in districts such as East Siang (Arunachal Pradesh), Birbhum (West Bengal), and Pune (Maharashtra), while chikungunya was most severe in Thanjavur, Theni, and Vellore (Tamil Nadu). A bivariate choropleth analysis identified regions with significant syndemic, such as Pune (Maharashtra), Tumkur (Karnataka), and Kamrup (Assam), which were classified as high-high. Additional districts such as Sangli and Satara (Maharashtra) were categorized as high-moderate, while Puducherry and Junagadh (Gujarat) were noted as moderate-high for dengue and chikungunya, respectively.
conclusionsThe findings underscore significant variability in dengue and chikungunya syndemic across India, highlighting regions with severe dual burden. Enhanced surveillance for close watch on syndemic occurrence and its impact needs to be studied, which is essential to reduce both the incidence and study its compounded public health impacts.
